Sustainable Drainage Systems (SuDS) with High-Performance Permeable Aggregates
Holcim’s SuDS solutions manage storm water, reduce flood risk, and protect waterways for sustainable, resilient developments.
Sustainable Drainage Systems (SuDS or SUDS) provide an alternative approach to traditional systems that use pipes and drains. By temporarily retaining and slowly releasing rainfall back into the waterways in a controlled manner, permeable aggregates diminish many of the adverse impacts of storm water run-off on the environment.
Holcim has been at the forefront of SuDS research and solutions in the UK since 2010, working with the Transport Research Library and CIRIA. With Holcim's SuDS solutions, communities can embrace a more resilient future while protecting our ecosystems and enhancing biodiversity.

Benefits of using SuDS Solutions
The Key SuDS Principles
Our SuDS Offering
SuperFlow is our high-performance permeable aggregates product range. Well graded, crushed angular particles mean optimal void retention and compaction for your project.

- Residential home zones
- Pavements and paved areas
- Sports pitches and stadiums
- Car and lorry parks
- Pathways
- Drainage channels and swales
- Sea defence

When used within a succession of management practices, control structures and strategies, permeable drainage like SuDS can efficiently and sustainably drain surface water while managing the water quality of local rivers, lakes and streams. Working hard to mitigate flooding and erosion while lowering surface water pollution. Join us in building a sustainable urban environment that safeguards both our cities and our waterways.
