STONEmaster

STONEmaster is a patented process used to refurbish roadside filter drains.  By recycling the filter media in-situ, only material not conforming to Type B specification is removed from site, whilst drains are left functioning fully. 

Fewer HGV transfers, minimal import from quarries and loads to landfill ensure this is both an environmentally sustainable and cost-effective method of prolonging asset lifespan.

Filter drains operating at their optimum performance level effectively remove surface run-off and sub-base moisture, to ensure roads are safer and last longer.
