5 Handy Calculators To Help You Install Artificial Grass


best artificial grass

We always recommend to customers that they use the services of a professional installer to lay their artificial grass for them.

But many people still choose to install their own fake lawn.

If you have the correct materials, the right tools for the job, a couple of spare weekends, plenty of patience and some help from a friend or family member, it is possible to achieve excellent results.

In a typical artificial grass installation, you’ll need to install a weed membrane, a sub base (typically comprising of MOT Type 1) and a laying course (0-6 granite dust or Grano) prior to laying the fake turf.

Before attempting an artificial grass installation, it’s useful to calculate the materials you’ll need and contact your local builders merchant or aggregate supplier to obtain prices.

Aggregates are typically supplied in what is referred to as, a bulk bag or ton bag, so we have rounded up quantities to the nearest bulk bag.

Usually, a bulk bag contains somewhere around 850kg and not a ton (it’s always advisable to speak to your supplier for more accurate information regarding the size of their bulk bags)

Bear in mind that as you’ll probably be buying your aggregates in bulk bags, you’ll more than likely have a surplus left over at the end of the job.

If your lawn is a large area, it may be more cost effective to have your aggregates delivered as a ‘loose load’.

This means that the aggregates will be tipped onto your property with a tipper vehicle. As this may be an option for you, we’ve also included the quantities in tons, as well as bulk bags.

Calculating the necessary materials can be a difficult task, but to make your life easier, below you will find 5 handy calculators that will help you calculate the qualities of everything that you’ll need.

Please remember that these calculators are intended as a guide only.



1. Weed Membrane Calculator

A weed membrane is used to prevent weed growth. On a typical installation, we recommend a double layer of weed membrane. One directly underneath the grass and another directly underneath the sub base material.

In some instances, such as when installing on top of concrete, you’ll usually only need a single layer, therefore we have allowed for both single or double layers on weed membrane below.

Rolls come in 2m widths as standard and can be purchased via our online store here.

2. Sub Base Calculator

This will calculate the quantities of MOT Type 1 required for the sub-base installation. We generally recommend this is installed to depth of 50mm (2″).

The calculator rounds up to the nearest bulk bag.



3. Laying Course Calculator

This will calculate the quantities of 0-6mm Granite Dust (or Grano) required for the laying course installation. We generally recommend this is installed to depth of 25mm (1″).

The calculator rounds up to the nearest bulk bag.



4. Joining Adhesive Calculator

The below calculator will calculate how many tubs of joining adhesive you will require if your lawn will have joins. It will calculate quantities in 5kg or 10kg tubs.



5. Sand Infill Calculator

To finish your installation, you’ll need to apply kiln dried sand to your newly laid lawn. The sand will support the fibres, add ballast and help to regulate the temperature of your artificial grass.

You can also buy silica sand infill that has been designed specifically for use on artificial lawns here.



Please remember that these calculators are intended as a guide only and quantities are estimated based on perfect working conditions. We cannot take responsibility for excess materials.

      Morning Danny,
      We take it you are referring to the MOT & Granite Dust?? If it is, then unfortunately we don’t sell these items. They can be bought from any good builders merchants.
      We do however sell the weed membrane, grass, joining tape, glue etc.

      Hi Derek,
      The sand really does need to be applied when you know there is a couple of good dry days, otherwise you risk the chance of it clumping together before it drops to the bottom layer.
      We recommend distributing the sand ideally with a seed spreader and at a ratio of 4-5kg’s per m2 of grass.
      Please be aware that the standard builders kiln dried silica sand is cut as a diamond shape which means the edges are quite sharp and can potentially cut through the grass fibres.
      Our silica sand is specifically produced for artificial grass and is produced as a rounded sand. Also our sand contains 97% silica as opposed to the builders sand which contains only 95%.
      If you wish to purchase from us, all details can be found on our website.
