Everything you need to know about Augers

An earthmoving auger attachment is a very specialized piece of equipment that is only ever used for one purpose, drilling holes.  Most other pieces of equipment that we own can be used for multiple purposes, making them efficient.  But there are times when a specialized piece of equipment is needed that only does one specific thing, and in the case of drilling holes, that’s an earth auger.  These precision tools help us to save time, which means that they also help us stick to the timetable that we commit to.

Augers Are Capable of Drilling Deep, Narrow Holes

An auger attachment is very useful in the construction industry because it allows for holes that are narrow and of varying depths to be dug.  Without an extension an auger can usually dig a hole that is anywhere from as shallow as a 200mm, up to as deep as 5 metres.  If you need to go deeper an extension can, be added to tunnel deeper into the ground.  Now that you see what an auger can do, you probably have a better idea of why it is such a valuable piece of equipment and how useful it can be.

When Would an Earth Auger Be Used?

Earthmoving auger attachments are ideal for drilling narrow holes, pier holes, such as for a column, fence post, pipe or footings.  While you can use an excavator or other tools to accomplish the same things, it’s much more difficult, and involves much more work than simply choosing the right tool for the job.

Can a Drill be Used Instead of an Auger?

An auger can drill much deeper than a drill and is far more versatile.  Now, if you only need to drill down a foot or two, then using an auger is overkill.  But, if you need a deep hole that is narrow as well, then an auger is the way to go.


Do we Have Personnel Trained to Use Earth Augers?

One thing that you can count on is that if we have equipment that we use, we have personnel that are highly trained in how to use it.  Our people are experienced in using all of our equipment. They can use it efficiently, and most importantly safely.  While there’s no way to be certain that we’ll need to use an earth auger when working on your property until we do an inspection, if we do, you can trust that the auger will be used by an experienced and qualified professional.

Bobcat vs excavator: What are the differences?

A bobcat or skid steer as they are known as, Bobcat is actually a brand name, skid steer is what the machines are, they can be hired in different sizes, in many different brand names, they either have tracks or tyres, most popular at present is the tracked skid steers, as they are more moveable, can travel over any terrain, and do not need to worry about punchers, as they have tracks not tyres. They come with a bucket on the front, which you can have a 4 in 1 bucket, meaning the bucket opens and shuts, this is a very versatile bucket, as you can pick up items and materials with a grabbing action. You can also level with this 4 in 1 bucket.

An Excavator is a completely different machine, It, has a boom like an arm extension, which has the bucket attached to it, you can use this attach different buckets/hammers/argues/ripper attachments etc, like the bobcat you can hire these excavators in different sizes. They are mainly tracked, you can hire with wheeled if required.

What Are Excavators Used For?

The excavators are versatile machines, as they can sit in one position and swing around to operate, plus they move forward and back, they do not move as quick as a skid steer, as skid steers are more for levelling/picking up materials and loading, as any excavator can do all this also, but they are more useful when digging service trenches/dams/pools/pier holes/septic holes/soak well and leach drain holes etc, where a skid steer is unable to on its own.

There are times when a shovel might work, but if you are digging anything major, then earthmoving equipment is going to be in order.  Large projects might include digging a trench for a pool or digging a trench to lay the foundation of a building.  Anything like that is going to require Earthmoving equipment if you plan to stick to any type of reasonable time frame and come in various sizes such as mini excavators.

Why is the Bobcat brand so well known?

Bobcat (Skid steers) has been around for more than 60 years and accounts for over 35% of the entire market of skid steers.  In that time they developed a reputation for producing tough, reliable equipment that performs well, even in less than ideal conditions.  But now there are so many manufactures now that are just as competitive as Bobcat is.

Skid steer Bobcats, are sold now with John Deer, Hi tachi, Komatsu, Case, CAT, Volvo, etc,   At Dobson Excavations we purchase different brands of machine, as different brands can handle different types of job sites, so this is why our excavators and bobcats we have are in multiple sizes so we can use the equipment that’s best suited for the job.…

What is the best time of the year to excavate a pool?

If you are thinking of building your dream pool, you’ve probably thought about the best time to build it. While there is no wrong time to excavate a swimming pool, there are several factors that you need to consider when deciding the best time to plan and build your pool.

Each season has its advantages and disadvantages when it comes to pool construction. You need to weigh each option before making a final decision carefully. This article explores each option and concludes the best time of the year to excavate a pool.


Spring is one of the busiest months concerning pool construction. This is probably because most homeowners target the warm summer months to enjoy their pool.

On the downside, homeowners will not get to enjoy off-season sales. The reason for this is that suppliers and pool builders have great demand. Also, the high heat and humidity can delay the entire process.


An advantage of digging your pool during summer is that the ground is dry, making it easier for contractors to get the job done with ease. Like spring, summer is also a busy season for suppliers and pool builders as they complete projects that begin during the spring months.

If you still want to build during these months, consider scheduling the excavation process at the end of the season when it’s not that busy. However, this means that you will only get to enjoy your pool in the warm summer months.


The most preferred time for excavating a pool is during Autumn, but before the rain starts. This is because months in the Autumn season have steady weather, making the pool installation process easy and less overwhelming. With the perfect temperature in fall, the contractors are capable of starting the project and completing it even quicker.

Furthermore, prices for pool excavation are cost-effective in Autumn months compared to those in summer or spring. Autumn months offer seasonal sales of the low cost of materials, shipping, transportation, and easier workdays. It is also easier to start and complete the project in the Autumn. The other benefit of excavating your swimming pool in the Autumn is that you will get to plant trees and vegetation for your backyard. You can plant and grow the plants before winter hits. This means that you will have a luxurious backyard by the time your pool is ready for use. Your swimming pool will probably be ready to use by summer when you start work in the fall or winter months.

Winter months

Besides fall, winter can also be a good time to excavate your pool. This is especially true if you have a low budget. Winter months also offer seasonal sales where prices of building materials are on the lower side. Besides, it is also a good time to negotiate the best deals with pool builders.

However, a downside of the winter months is the cold weather. It can be difficult and risky to dig a pool with frequent …

Top ways to improve a driveway with potholes

Whether your driveway is made of gravel, limestone, asphalt, or concrete, potholes are likely to be a nuisance. Since potholes will not fix themselves, you will need to find a way around them or risk damaging your car. Don’t wait a long time before setting this issue. The longer you wait, the worse the situation may become.

This is the job for wet hire companies, including a reputable one from Perth, Dobson Excavations. You can rest their equipment and staff to improve your driveway with potholes by doing the following:

The preparation phase

Since gravel and dirt potholes result from trapped water beneath the surface, you should work on improving the underground drainage quality to avoid future recurrence.

At Dobson Excavations we will rip the surface, scarify and roll the surface, if more product is required then they will lay more material over the areas.

Gravel and Limestone driveway pothole filling

All areas of where the potholes are would be ripped, the area scarifies with a bobcat, if gravel or limestone is required then this would be laid over the areas and a vibrating drum roller would complete the job to smooth out the area.

Asphalt and concrete driveway pothole filling

For potholes in Asphalt and concrete driveways, would be done completely different to Gravel or Limestone. With Asphalt you can use an asphalt filler, clean the area of all debris and dirt if the area in the pothole is dry soil you may want to dampen the area. Then fill in the potholes with either crushed limestone/rock or concrete to about 2 inches below the pothole, then fill with asphalt filler. Compact with small areas with a plate compactor, and then let the sun dry it, if rain is expected you will need to cover the area.

As for concrete, you will still need to remove any debris and dirt from the pothole. You will need a concrete mix to fill in the hole, you can buy ready made products where you just add water and mix. You fill the hole level with the concrete driveway, scrap off any excess concrete and allow to dry.…

Why is a sand pad required before constructing a shed or house?

You may be already used to seeing sand at the beach and may think that it has no important part in people’s lives. But did you know that the houses you live in and the streets you walk on are built using sand?

When talking about sand in building, it usually refers to the material that’s much firmer than the sand grains you’d find on the shoreline. It should also be clear of stone blocks and other contaminants.

Understanding the sand pad can be tricky for a first-time homeowner. Continue reading to learn everything there is to know about the sand pad.

Why is a sand pad required before constructing a shed or house?

You need the help of specialists, such as the Dobson Excavations in Perth, to make a proper sand pad. We work with reliable sand suppliers and certify the sand pad before putting up any structure. This is important since it will lay the foundation or groundwork for the project. You need something solid and durable for this purpose.

Different types of sand for sand Pad

Numerous varieties of sand can be utilised in construction, each for a distinct purpose. Therefore, it’s critical to understand that not all sand is the same.

Clean Fill Sand

Sand for House pads has to be certified to build the house on and must be free of any debris, Fill sand is straight of the face, which means it is Natural with small granules, and just the right amount of clay for compaction for sand pads for houses, sheds, water tanks etc.

Plaster sand

Also known as rendering sand used for exterior wall rendering, once combined with the ratio of water and cement has great adhering characteristics, it can also be used to set paving.

Brickies sand

This sand has a content of clay and fines for a more workable sand, it is used in mortar for brick laying and also can be used in Limestone Block construction.

Paving sand

Used in shaping, screeding and sculpting, compromise between both Plaster and Brickie sand. Has strong compaction and setting strength, without even using little or no cement or bonding products.

Compacting the sand pad

In a construction project, sand compaction involves using mechanical force to densify a soil by minimising the space between sand grains. The key objective of the procedure is to create a solid working foundation, so experts must complete it with the appropriate skills and equipment.

Soil compaction equipment comes in a variety of styles and combinations, such as the number of drums and vibratory system. All types result in increased soil density, which boosts the supporting power of the soil.

These machines have rubber tyres that are separated and have varying air pressure. They usually have ballast mechanisms that adjust weight as needed to achieve compaction requirements.


Used to compact sand pads, it has a metal compactor plate, which in combination with the vibration of the plate compacts the sand. Used on each layer of sand to …

Safety precautions to take in an excavation project

Many accidents have been witnessed during excavation due to the earth caving in or sliding away. In some accidents, workers are buried, and there is a loss of life due to suffocation. On the other hand, when excavating next to existing structures, they can come tumbling down if you are not careful.

Excavation is the first work that is done on any site. You do not want accidents to be the first occurrence in your project. This is why you must know about the safety precautions necessary for any excavation project.

Here are some safety precautions to remember when doing an excavation project:

Proper planning

Proper planning is essential to implement the right worker safety precautions. Several things need to be addressed by a professional in advance.

The first step is to evaluate soil conditions for the right preventive systems to be determined and implemented. Other planning activities include planning for the excavation site’s traffic control and establishing the proximity of any nearby structures.

It is also vital to ensure that the workers have the right protective gear.

Plan for a safe entrance and exit

The entry and exit into the excavation should be included in the protective system to keep workers safe. You could provide ladders, ramps, stairways, or any other safe means for exiting from the excavation. Sometimes, when dangerous conditions happen at the excavation site, survival depends on how fast the workers can get out.

Undertake potholing and Underground Service Locator

Since using diggers is considered a risky activity, it is advisable that you first take the time to do potholing before you commence the actual excavation. Potholing involves digging small test holes to check for underground obstructions like pipes or lines. It is a reliable way to locate underground utilities so that the excavation operators can bypass them.

Another option is to hire an Underground Service Locator, they use Ground Penetrator Radar equipment. They will also obtain all the Dial as You Dig information. This is most efficient and time saving way to locate underground services.

Surface safety

An excavation site should be properly protected. This can be done by placing barriers around the excavation site. All spoils and excavation equipment should be placed a far distance from the edge of the excavation dig site.

Spoils refer to the excavated material, and it can be dangerous if it is placed too close to the edge of the site. The weight of the spoils or excavation equipment can easily cause a cave-in. They can also roll back into the excavation site causing life-threatening injuries or even death to the workers.

Routine inspection

A trained professional should inspect the excavation every day. The inspector should look for any possibilities of collapse or cave-in before work begins in the morning. Inspection work should also be undertaken immediately after a natural event such as a rainstorm. It is also advisable after impactful works such as blasting of rocks at the excavation site.

Have proper safety signs

The importance of …

Is it possible for an excavator to operate on a slope?

Excavators are commonly used in construction projects due to their ability to dig trenches, pits, and foundations. Also, they are available in different types and sizes, offering you more alternatives for using an excavator that is ideal for your needs.

In most cases, the topographical condition of the project will often define the type of excavator you will need to use. Nevertheless, you don’t always get to operate on flat, smooth terrain; sometimes you have to deal with hills or even sharp angles.

Working with any type of machinery on some steep terrain will surely demand specific abilities and perhaps additional tools. Continue reading to learn everything you need to know about working with an excavator on a slope.

Critical factors while operating an excavator on a slope

Gravity is the most crucial thing to consider in this scenario. As we all know, the machine’s centre of gravity alters as it turns from side to side. As a result, the risk of overturning and rolling increases on a higher incline.

Obviously, you would want to avoid the danger of toppling large machinery down a steep hill. This is why you must ensure that the operator thoroughly understands how to maintain the machinery’s centre of gravity and proceed with caution throughout the procedure.

Lubrication is the second most significant component. Oil, fuel, and lubrication keep the excavator engine going while it shifts and moves around on a hillside. Unfortunately, if the inclination is too great, the engine may fail to consume the liquids, potentially resulting in malfunction or damage.

How to successfully operate an excavator on a slope

Working with an excavator on an inclining ground is a dangerous task, as illustrated above. Here are some suggestions to help you avoid any possible risk or even a life-threatening circumstance.

Using the right excavator

A long reach excavator is the best choice for the job. The machine’s long arms allow it to stay steady on flat ground, while the extra-long digging arm allows it to reach awkward spots on the slope. This makes it possible for the machine to successfully dig on slopes and at an angle.

Examine the hill’s condition

The solidity of a slope is affected by a variety of factors, including loose gravel, dirt, and also rain. When operating on unstable ground, a heavy engine like an excavator may slide or slip because of its own weight.

If there is a risk of falling material, consider clearing the area first before proceeding with the job. Also, keep an eye on the weather forecast and wait a day or two for things to improve.

Most importantly, keep in mind that excavators are not designed to be used on slopes steeper than a 35-degree angle. If you are uncertain, consult the project team’s surveyor to determine the slope’s inclination.

Carefully plan the working direction

Finally, instead of working sideways, it would be best to plan your working direction up and down. This is because you want additional weight behind to balance …

Can you operate a bobcat without experience?

Can you operate a bobcat without experience?

Are you wondering if you can operate a bobcat even if you don’t have any experience? The quick answer is yes. You can definitely operate it without any experience. However, these are the reasons why you shouldn’t:

Damage to properties

Bobcat machines, also known as skid steer loaders, are commonly used for excavation, demolition, and debris removal. All of these tasks require a precision operation to ensure safety and efficiency. However, a person with a lack of experience is bound to make mistakes. In these cases, the mistakes can cause serious damage to property.

For example, the inexperienced operator might be able to control the machine into the right dig site, causing damage to the concrete or land. They might also steer the machine incorrectly or damage the fence.

All in all, operating a bobcat is not as simple as driving a car. It requires precision which is only possible with the right skills and experience.


People with no experience in operating a bobcat might cause it to overturn, injuring themselves as a result. Worse, they could run over other people causing death or injury due to having no experience.

Another reason why you should not attempt operating a bobcat when you have no experience is that you might cause an accident. There are tons of things that might go wrong, like not manoeuvring the attachments properly or not being able to drive the vehicle safely.

The solution

If you think that operating a bobcat on your own is risky due to your lack of experience, then what are your alternatives? Well, the best solution is for you to get in touch with a wet hire company such as Dobson Excavation.

A wet hire company is a service provider that allows you to hire heavy equipment along with a qualified operator. Here are the top benefits of hiring a wet hire company instead of operating a bobcat on your own without experience:

Experience bobcat operator

The main benefit of a wet hire company is that they will connect you with a qualified operator for the machine that you will be renting. These operators are trained and have years of experience operating various construction types of machinery under their belt. From large excavators to mini bobcats and mini excavators.

Safety and efficiency

If you don’t have experience in operating a bobcat, chances are you will spend a significant amount of time figuring out how to make it work. If you are renting the machine, that amount of time you are learning how to operate it is not only consuming your time but is also literally causing you money every minute. On the contrary, if you opt for a wet hire company, the machine, and the operator can go straight to work to speed up your tasks.

At the same time, since the operators are trained and experienced with the machine, there are fewer chances of them getting into an accident, making …

Auger holes: What are they and why do you need them?

If you have an upcoming project, you may have already come across an Auger machine. But what exactly is it, and do you need it for your project?

What are auger holes?

An Auger hole is a hole drilled by a rotating column or metal shaft with blades that circles the edge. It is commonly used for drilling holes and works by rotating into whatever material you want to drill a hole into. Its outer edge blades can cut through tough materials and pull them up so that the hole is clear and empty.

The main components of an Auger hole equipment are:

  • Tang: This refers to the topmost part of the Auger that attaches to the machine that powers it.
  • Shank: This is the part in between the blades and tang.
  • Twist: This part of the Auger refers to the series of twisting blades that cut and pull up the material you are drilling a hole into.
  • Spur: This is located at the bottom of the Auger holes.
  • Cutting Tip: This part is most commonly found on smaller Augers holes.
  • Feed Screw: Same with the spur and cutting tip; this is located at the bottom of the Auger hole and is more common on smaller Auger holes.

Auger holes are commonly used for the following projects:

  • Planting trees
  • Building foundations
  • Installing telephone Poles
  • Fence Posts
  • Test Holes

It is also commonly used for projects that require bigger holes to be excavated. However, take note that the drilling power of the Auger hole is not its blade but rather on the machine which powers it. So, you can consider it more of an attachment than a stand-alone machine. The more powerful the machine is, the less effort for the Auger hole to pull up the soil.

Benefits of auger holes

The Auger hole is not just a fancy attachment because it does come with plenty of benefits. These include the following:


Manually drilling holes can be time-consuming and punishment for your whole body. It can also take days to dig the depth and width you desire. But, Auger holes allow you to get a deep hole in a matter of just a few minutes.

In addition, other drilling machines require you to get your hands dirty because you have to remove the dirt inside the hole manually. Again, this can be a time-consuming and tedious task. But, with an Auger hole, the dirt is pulled up, allowing you to get a clear hole.

Quiet operation

The problem with other drilling machines is that they can be quite noisy. As a result, your construction project can inconvenience neighbors and other nearby establishments because of the noise pollution that it creates. Compared to other drills, an Auger hole is relatively quieter because it does not use a pounding action to drill holes.


Auger holes can be economical because they cut back working hours, allowing you to keep deadlines. Aside from that, less manpower is required, so you don’t have …

Reasons for Using a Roller in Driveway Construction

A driveway gives access to homes, garages, or parking lots. It also adds appeal to your home’s exterior. A well-built driveway ensures the safety of the people and vehicles while utilising it. In constructing a driveway, you have several choices for the primary outlay material. You can choose from finishing it with concrete, limestone, gravel, bitumen, asphalt, or pavers.

Building a strong base

Whatever your choice of construction materials, how you establish the base of the pathway matters the most. The bottom base determines the strength and durability of the driveway against the daily load it has to support.

In building a solid base for your driveway, you have to deal with the bottom surface, and top surface or overlay of your driveway. With every stage of construction, employing a roller is significant in building up a strong base and ground for the driveway.

Here are the advantages of using a roller in constructing your driveway.

Level the ground well

Upon cleaning the soil and marking the area for your driveway, it is time to level up your space. You may need to add more soil or excavate a little to take the dirt out. After that, you have to compact the ground sufficiently. It’s better to use a roller since it provides sufficient weight to compact the bottom layer. Another advantage of a roller is that it spreads out the soil evenly within your marked area.

It compacts stones and aggregates

When you are done compacting the bottom layer of the driveway, your Excavation business will supply and install the gravel you require, depending on the site they will drop loads off in the area which requires the material and spread with a bobcat. Then the surface will be rolled to compact the surface, watering maybe required if completed in warm weather. The water helps to keep the material moist, binding the material together when rolled. Rolling gravel driveways makes for a much smoother surface, the gravel adheres together prevents tripping for people walking over it and unexpected events where rock loses from the pavement.

It creates a solid ground for asphalt or concrete overlay

If you choose to lay some asphalt or concrete on the surface of your driveway, the layers you have paved with rollers make excellent foundations for the surfaces. A vibrating double drum roller compacts and flattens the …
