Clay becomes hard and if upgrading or maintence is required, then to dig it up will be hard digging which could cause damage to cables.

Pool Removal or Installation Perth-Keysbrook-Harvey-Bunbury

Pool Removal or Installation Perth-Jarrahdale-Bedfordale-Armadale

Is the pool in your back yard not being used?

Kids moved out or no help to clean the Pool?

Decided you require more room and pool taking up the space?

We at Dobson Excavations will assist with your pool removal or fill in. There are 2 options to consider,

  1. Removal of a pool all together is where the fibre glass or concrete is broken up and trucked away, the pool is then filled in, once completed a certification certificate can be supplied if a building is to be built on the old pool site.

2. Fill in of a pool is where the fibre glass or concrete has holes hammering in the bottom of the pool for water to drain then filled with material, this is a less cost effective way but the only                    downside is your unable to build over it.

Pool Installation

Dobson Excavations can excavate your hole for any size pool, if Rock is a problem then we can hammer the rock out, our 6ton and 21 ton have rock hammer attachments.

What a Bobcat with Tracks is used for Perth-Mandurah-Pinjarra-Harvey-Bunbury

What a Bobcat with Tracks is used for Perth-Mandurah-Pinjarra-Harvey-Bunbury

Wanting to Hire a Bobcat for site works?

Operation of a Bobcat on site Constructions.

Wheeled Bobcats are very limited, they are used for rocky areas, Bobcat with Tracks does not fair well in rocks but basically that is the only terrain they can not work in. Tracked Bobcats are more versatile as they are used in Sandy/Muddy and Soil sites. They compact the ground more sufficiently than a Wheeled Bobcat. Their tracks glide through muddy site where Wheeled Bobcats slip and bog down, causing more mess and becoming stuck.

Tracked Bobcats can lay and compact sand pads quicker than Wheeled, Track Bobcats have smoother results, as the Tracks allow more moveability.

Tracked Bobcats can complete the following site works.

Sand Pads, Loading Trucks, Driveway Construction, Soil/Sand/Mulch, etc which they spread/Lay and move around sites, Level sites etc

To Hire a Tracked Bobcat contact Bruce on 0144 755306 at Dobson Excavations who are fully licenced and insured.…

Why we use only quality materials on our driveways and some of our competitors do not Perth-Bedfordale-Roleystone

Why we use only quality materials on our driveways and some of our competitors do not Perth-Bedfordale-Roleystone

Constructing a new Driveway?

Wishing to use Gravel either in red or blue, or maybe Limestone is required for the new Driveway?

At Dobson Excavations we can supply, lay and compact the driveway, as we use only use quality grade materials. Only quality products will give your driveway a much better finish and last many years. You may think by saving a few dollars on lower grade materials will save money but in the long run, you will only have to either repair or replace your driveway in a short period of time.

There are a number of different grades of gravel and limestone, limestone is usually used to construct a driveway for building sites so trades can access the site, later on when building is completed then gravel can be laid over the top.

The key to a driveway lasting longer is the definitely the materials used, but it is must at the end of the job to compact the driveway. If it is not compacted then the gravel will move and not last long at all. If too much rain gets on the driveway if not compacted the materials will just wash away. The other important key is drainage of the driveway, either using roll overs to divert water or drains. It all depends on your block whether it is flat or sloping. But if you contact Bruce at Dobson Excavations he can assist in advice on these concerns.

So if you require your driveway to last for years to come with a Professional and Quality finish then contact Bruce on 0414 755306 for a free quote.…
