Subbase

Constructing a proper sub base before fitting the actual artificial grass surface is very crucial for outdoor pitch. Together with the right sand and rubber infill, it guarantees a superior quality artificial grass pitch, with less maintenance, safe to play on and available whenever needed.

This permeable and reliable drainage system sub base consists of several layers. At the bottom, flexible drainage pipes are installed, bedded in a layer of coarse sand, levelled and stabilised. On top of this comes a stabilizing and draining layer (commonly using lava, crushed stone or asphalt). Then a sports technical layer can be installed under or in the artificial grass surface to keep the pitch’s dynamic properties intact. Depending on the sport activity, certain degree of slope is strongly suggested to help the flow of heavy rain water.

Proper sports technical layer also allows for better and more constant ball behavior (ball roll and bounce) combined with excellent shock absorbent qualities. Different constructions of the sports technical layer are possible. It is recommended to install a geotextile to ensure a balanced pressure of the construction, whilst protecting the artificial grass layer as well as the sub base.
