The invention relates to a permeable base (10) for a road, path or playing surface (100). The base comprises a geotextile (20), a layer of aggregate material (30) above the geotextile, and a geonet (40) above the aggregate material. The base also comprises a binder (50) which adheres the aggregate material together to form a cohesive aggregate layer and which also adheres the geotextile (20) and geonet (40) to the respective bottom and top surfaces of the cohesive aggregate layer. The resulting bound aggregate base is durable, permeable and is relatively straightforward to install compared to known systems. The invention also extends to a sports or playing surface, a path, a road surface for vehicles, and to a golf bunker, comprising a base in accordance with the invention and a surface dressing layer (60) above the base. It also extends to a method of constructing a base. |
