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.

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 compact the pad, so that when a penetrometer is used it will determine the compaction and if it is suitable to build on.

Smooth rollers

These machines use static pressure to compress dirt, sometimes in combination with vibration. Smooth rollers are most likely used to generate a smooth construction area in the finishing compaction process. Can be used on smaller sand pads and driveways.


If you’re sand pad is not correctly compacted then you foundation of sand could cause house movement after building, or concrete slab issues where it could crack.
