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 sub-base consisting of type 1 limestone combined with a layer of sharp sand 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 aggregate base is especially important if play equipment or trampolines are being used.
