How do artificial lawns drain water?

Our artificial grass drains water and is often chosen as an alternative for a lawn with poor drainage. Poor drainage may occur in a lawn that does not face the sun, has a high clay content, or is mostly rubble as is the case on a lot of new builds. We install our lawns with a sub-base to keep the lawn stable and to allow for the drainage of water into the ground below.

After the existing lawn is removed to a depth of between 55 and 70mm, a sub-base consisting of type 1 limestone then a layer of grano dust is distributed. Limestone is the most porous type of aggregate as it is made from permeable materials. This covers the entire lawn area at an even and consistent level ensuring a stable draining base for years to come.

The roll of grass is manufactured with a holed backing that is concealed within the pile height and not visible when laid. Water simply drains straight through these holes and into the aggregate base below. As you might expect, after heavier rainfall the grass may take longer to dry than with a light shower.

Please note if you intend to lay your grass on top of a surface such as decking, tarmac or paving which has poor drainage then artificial grass will not improve the drainage as there is no change to the existing base.
