PRODUCT GUIDES

Sand Types

At Centenary Landscaping Supplies you will find a range of sands that will allow you to complete a wide range of jobs… from laying bricks and pavers, to building a sandpit.  There are a few important things to know about our sand types: as with all landscape and building products, cleanliness is extremely important and to that end, all sands products are stored in individual concrete bays with a concrete floor to reduce the chance of contamination. Secondly, whatever the size of the job at hand, you can purchase exactly the right amount. All products can be bought in amounts as small as a shovel; through to bags, trailers and ute loads right up to full truckloads, when that’s what is needed.

What do you need your sand for?

We have a wide range of sand types available. Below we will outline the most popular projects you may need sand for and outline the suggested type. You can be assured that if you have a job to do; we will be able to supply the sand you’ll need!

 

Bedding Sand
Bedding sand is a washed and screened coarse river sand, which is easy to screed (level) and use under pavers. It comes from a freshwater origin so it is not laden with salts which can cause Efflorescence on the paving surface.

Brickies Loam

This product is used by many local bricklayers and is actually a blend of clean fine washed sand and a loamy (clay) sand that sticks or adheres to the bricks. This makes it easier to use when laying bricks and is specifically for this job. If you are going to be laying some bricks then the following pointers will be helpful:

  • Mix brickies loam and grey cement in a 4:1 mix (about 12 – 14 bags of cement per cubic metre of loam). Consistency should be like clotted cream. Always use a plasticiser (just ask us) to make the mix “smoother” and easier to work – adding lime also makes the mix more pliable and stops the sands and water separating (ratio should be 4:1:1 approx).  It is often asked if dishwashing liquid can be used instead of plasticiser. The answer is basically, “Yes, but is not recommended”.
  • Finally, you will need approx 1.5 Tonne of sand for every 1000 bricks, although it will depend on the brick being used and how neat you are!

Washed Pit Sand

As the name suggests, this is a clean, fine, washed sand that is used when laying the “heavier” concrete or Besser type blocks. It is often preferred to brickies loam as it isn’t squashed out of the joints as easily by the heavy blocks.

  • Use Washed Pit sand, lime and grey cement (about 14 bags per metre) in a 4:1:1 mix, again using plasticiser. This time the mix should be drier so that the weight of the blocks doesn’t squash the mix out the sides. The consistency should be like smooth peanut butter.
  • For both blocks and bricks, if you need the colour of the mortar to be white, then you will need to use White Sand mixed with an Off-White Cement but be aware that it doesn’t mix as well as the two other sands above making the use of Lime and Plasticiser even more important.
  • Other colour mortars can be achieved by mixing a coloured Oxide (powder dye) in with the mix. There are a number of basic colours available but trying a small batch first would be advisable.

Washed Pit Sand

While rendering is spreading a thick layer over the wall, bagging is just a smear.  Use washed pit sand, cement, and lime in a 2:1:1/2 ratio with a plasticizer.  Wet the wall before starting… but do not soak it. The mix should be quite runny.  Use a sponge and smear the mix on, making sure you wash the sponge out every 3 or 4 applications so it doesn’t get clogged up. Bagging is much easier to do than rendering and if it’s going to be painted it will look good too.

Washed Pit Sand (often called Plasterers Sand)

  • It must be stressed that rendering is not an easy task and should be approached with caution.
  • The biggest risk with rendering is that as the render dries, it shrinks and separates from the wall, creating a small void. It may even be worthwhile getting a professional to give you a quote first. If you decide to continue yourself, you will need to mix the washed pit sand with grey cement and lime in a ratio of 2:1:1/2. (Approx. 24 bags of cement per metre of sand) with the consistency being that of clotted cream.
  • The wall needs to be painted with a bonding agent which should also be added directly into the mix itself.  A bonding agent will help the mortar or render “stick” to the wall. So how much do you need? Well, at 10mm thick, you will use 1.5 Tonne per 100sq metres of wall.

White Sand

This is the cleanest sand available and is used extensively in the local schools and day care centres often for that very reason.

Some other points to note:

  • If you are filling a “Clam Shell”, then 3 bags of White sands will be enough for one half and they will easily fit in the boot of the car.
  • A fairly standard size for a Sand Pit would be 1.8m x1.8m x 15cm deep. To fill this area would take a half a cubic metre (or 750kg) which will comfortably fit in a ute or a trailer. To give you an idea, this would probably equate to about 6-8 wheelbarrows full…..so it won’t take you too long!

Jumping Pits (at schools)

Washed Pit Sand, Certified Play Sand or other specialist sands such as Soft Fall Sand are generally used for these applications. If you are looking for a specialist sand for such an application, please speak directly with a team member. 

Washed Pit Sand or USGA Sand

If you have a particularly fine lawn and use a cylinder mower then this is what you need and this product is used by Bowling and Golf Clubs alike. USGA Sand is (United States PGA certified sand) specified for use on Golf Courses around the world.

Medium Bedding Sands

If you have a lawn laid on a very heavy clay and you are trying to improve the drainage, then either of these two will help. The best way to start is through lawn aeration (punching hundreds of holes in the surface) and then top dress, letting the coarser sands particles drop into the many holes, thus improving the drainage of the area.

Slab Fill Sand

In most cases (e.g. irrigation, stormwater, and electrical conduits) the sands to use here is basically the most economical which is Slab Fill Sand. All that is required is a screened product that will fill in around pipes and not clump together. Please be aware that if a plumber is working on your property, they may well require a specific grade, especially if laying sewerage pipes, so always check with your plumber first. The plumber may well ask for coarse sand or even a 5mm sand and this request matches with our 5mm Drainage Gravel.
