Which Sand Do I Need?

Sand is loose particles of hard broken rock comprising of grains from disintegrated rock. The diameter of grains range between 0.06mm and 2.0mm in size and vary in shades of brown, orange and down to white in colour. Sand provides bulk, strength and other properties to construction material, helping make asphalt and concrete and can also be used as a decorative material in landscaping. Specific types of sand are used in the manufacture of glass and as a moulding material for metal casting. Other sand is used as an abrasive in sandblasting and to make sandpaper. Sand is a significantly important material for the construction industry, but this important material must be purchased with all care and vigilance.

Premium Washed Sand

Also known as white washed sand or sand pit sand, Triple Washed Sand is a high quality sand which is perfect for children’s sand pits. It is also the perfect base when laying paving and installing retaining wall systems and joining between pavers. Triple Washed Sand may also be used in concreting, fine rendering and plastering projects.

Uses for premium washed sand:

  • Children's Sand Pits: Our premium washed sand is a child friendly product, certified, washed and screened and is the ideal sand for kids sand pits
  • Under Paving: Sand can be used as a base for paving in areas where there is pedestrian traffic only. Allow a 30mm depth for the sand base making sure the sand is leveled to a smooth even finish, checking the fall with a level
  • Top dressing instant turf: Top dressing newly laid turf with washed sand adds weight to the turf, improving root to soil contact, it also stops the edges from drying out too much. Keep in mind that the top dressing should be no more than 10mm thick
  • Concreting: when using for concrete mix use the ratio 1 part concrete, 3 parts sand and 3 parts 14mm aggregrate
  • Rendering: To get the best results from a render coating, it is important that the mix is suited to the background surface, use the following guide to find your perfect mix

White Brick Sand

Also known as fatty sand. ‘Fatty’ refers to the high clay content in the sand, which repels water (like fat) allowing the sand to become stickier and more workable when mixed with cement. It is easy to work with when laying bricks, as it is compressible and oozes out of the joints.

This sand has the same fatty qualities as the yellow brick sand but is an off-white colour. Because of the clay content in the sand it is useful as mortar in block and bricklaying, as well as in bagging for walls. Like the yellow, its good compacting properties make it suitable for use under pools, although the cleaner white colour is more usually sought for its off-white colouring effect.

Uses for white brick sand:

  • Brick and Block Mortar: SoilWorx White Brick Sand is blended with cement and hydrate lime (6:1:1) which form the perfect builders sand. It is a light, grey coloured sand and is used when a light coloured mortar is desired. 1m3 of our white brick sand is enough to lay approx. 1000 bricks
  • Bagging for Walls: Bagging is done with a pre-mixed mortar made with cement, sand and a plasticiser, such as hydrated lime. Lime makes the mortar more workable and improves its ability to deal with heat and moisture once applied. Mix 6 parts sand, 1 part cement and 1 part lime, but mix in a bucket to achieve a creamy texture
  • Base for Above Ground Pools: Before your pool can actually be installed a level surface must be created that will allow for support of the pool shell. This surface is created with sand. Use a 1 inch layer as buffer only, do not use sand to level

**Brick sands are generally a naturally occurring material and colour variation will occur. The sand supplied to any job should be delivered in one load or lot as there may be variation over time or even day to day as different areas of a quarry are mined producing sands which could affect your projects.

Concrete Sand

Concrete sand is a naturally occurring material with a nominal size of generally less than  5mm. Typically washed and screened during the production process, the sand has a larger particle size with aggregrates through it which means it significantly improve drainage and soil structure when mixed through heavy soils.

Uses for concrete sand:

  • Perfect for all sorts of concreting and kerb projects

Concrete Mix Ratios:

Concrete Mix Ratio-1

  • In propagating and potting mixes: Concrete Sand is often the best rooting medium to use as it makes cuttings easy. When mixed through heavy soils, it can permanently improve the structure and drainage

Packing Sand

Typically a naturally occurring material that has a high clay/fine silt content. It is a fine, compactable fatty packing sand with some clay content in it.

Uses for packing sand:

  • Mainly used under concrete slabs: Create a barrier between the concrete and the soil by pouring a 50mm - 100mm layer of sand or gravel into the bottom of the frame, this will prevent the clay soil from absorbing moisture from your concrete
  • Base for water tanks: The most suitable base for a water tank is made of concrete or boxed in and compacted sand. Ensure base is compact and sturdy prior to laying down the sand. Base should be anywhere from 25mm to 50mm high when compacted

Silver Sand

A fine white sand used in gardening consisting largely of quartz particles that over time, through the work of water and wind, has been broken down into tiny granules

Uses for silver sand:

  • Overlay for synthetic grass: The main use for Silver Sand in landscaping is as an overlay for synthetic grass. Decorative artificial grasses generally have blades ranging 25mm to 45mm which need support in order to stay upright. After installation, use a broom to brush up the lawn and spread silver sand as evenly as possible aiming for a depth 5mm-10mm depending on the pile height of the lawn. Don't forget to brush again to distribute the sand evenly

A2 Filter Sand

A washed, well graded sand meeting VIC Road specifications. Generally a coarser sand with minimal fines to allow the free drainage of water through the sand layer. It is predominately used in drainage applications that requires the free drainage of water through the sand profile.

Uses for A2 filter sand:

  • Transistion Layer for Raingardens: The transition layer conveys water to the drainage layer while preventing the finer particles migrating from the filter media and clogging the drainage layer. The depth of A2 filter sand will depend on the composition of raingarden.
