SteelSuDS is an environmental SuDS solution. By reducing the volume and rate of runoff, it prevents overwhelming drainage systems during heavy rainfall.
Ideal for lowering runoff and increasing the effectivenes off your drainage system. From driveways and carparks to footpaths and industrial and retail units, SteelSuDS is available in both surface and binder layers for a complete SuDS system.
SteelSuDS is a highly durable porous asphalt. It possesses outstanding drainage characteristics, exceptional resistance to surface scuffing and excellent noise-reduction properties
The local authority approached SteelPhalt for a porous asphalt solution, originally specifying a natural aggregate asphalt.
SteelPhalt offered its 10mm SteelSuDS product because its porous and high fatigue-resistant properties made it ideal for rain to drain through to care for the roots of the trees.
55 tonnes of SteelSuDS were laid in 2024, and the material is performing as expected.
