One of the main reasons to buy artificial grass is to save yourself from muddy messes. Trulawn always lay an aggregate sub-base when installing to ensure easy and free draining.
After the existing lawn is removed to a depth of between 60mm and 80mm, a stabilisation geo-textile is laid to prevent any materials migrating into the ground. A sub-base consisting of type 1 limestone is then installed to a depth of between 40mm and 60mm. Limestone is a porous type of aggregate, which allows for reliable drainage. Then a layer of grano dust is installed to a depth of between 15mm and 25mm. Both of these layers are compacted individually and smoothed off at an even and consistent level ensuring a stable draining base for years to come.
