Does My Artificial Grass Need a Kiln Dried Sand In-Fill?
19th May 2016 | by Burts Grass | posted in News
None of our ranges require a sand in fill but there are many advantages of choosing this method of finishing your artificial grass.
If you do not sand fill you need to provide a firm and stable perimeter edging to fix the grass to. We would not recommend putting a sand in fill on artificial grass that is either a single colour or has a pile height of less than 15mm. However there are benefits of applying a kiln dried sand layer to your new synthetic turf installation.
It is important to note that you should only ever use kiln dried silica sand that is best purchased at a local DIY store. Do not be tempted to use other inferior products such as builders sand as this will be difficult to apply and also lead to problems such as weeds growing, etc. The approximate coverage is 4 to 5kg per sqm.
- Large areas of non-sand filled systems can expand with heat during hot weather. This creates sagging and ripples in the turf that look unsightly and can cause tripping hazards.
- Sand infill stabilises the installation without needing to install a perimeter frame to fix the grass to. Frameworks to which the grass is fixed to pose problems when the newly installed ground works settle.
- Non-sand filled areas might not lay as flat as you would like in contoured or uneven areas but a sand in-fill will weight down the grass holding it in place.
- Some longer piled surfaces without a sand fill will have limited fire resistance.
- Dogs and Cats – non-sand filled surfaces are more susceptible to damage due to the base of the grass being clawed at by your pet.
- Generally there is no reason not to sand fill the surface. The only benefit to non-sand fill is to the installer, as he does not have the issue of transporting the heavy sand, enabling the installer to cut out a timely process to gain on margins and appear to install at a cheaper price than competitors who sand fill.
