Steel slag sustainable drainage system (SuDS) benefits both the environment and water management.
SteelSuDS™ is a sustainable porous asphalt solution consisting of 95% steel slag aggregate that will reduce surface water to allow effective drainage that meets even the toughest of design requirements. Its porous properties make it ideal for a variety of applications such as driveways, carparks or sports grounds where a porous asphalt solution is specified.
Reduce flood risks, cost and your carbon footprint.
SteelSuDS is an environmental SuDS solution. By reducing the volume and rate of runoff, it prevents overwhelming drainage systems during heavy rainfall.

Application opportunity
The local authority approached SteelPhalt for a porous asphalt solution, originally specifying a natural aggregate asphalt.
Recommended product
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.
Results and benefits
55 tonnes of SteelSuDS were laid in 2024, and the material is performing as expected.
