Our products are one of the best Sustainable Urban Drainage Solutions available.
A SUDS compliant subbase build up should contain nothing smaller than 2mm in its construction, this is referred to as a ‘no fines’ or ‘reduced fines’ build up. By using a reduced fines subbase material such as type 3 or 4-40mm clean aggregate, below a grit bedding layer, the water is able to infiltrate through the complete build up and back into the subsoil.
Whilst all of our grids are completely porous and can therefore form a SUDS surface course, the free moving loose aggregate layers required to form a truly SUDS compliant surface can prove difficult to compact adequately to provide a sufficiently stable subbase.
Our CORE Commercial grid is ideal for projects where a truly SUDS compliant surface build up is required. The perforated HDPE base provides maximum stability whilst allowing the water to flow freely through the surface course.
The moulded ground spikes improve the structural integrity by anchoring the grids into the aggregate bedding layer, the perforated HDPE base forms a structural layer between the aggregate bed and the aggregate within the grid forming the wearing course.
