Capillia™ is a range of Sustainable Urban Drainage Systems (SuDs) sub-base aggregates that are used in and compliment the variety of systems available in the market today. Rainfall drains through the pervious pavement and filters into the sub-base, either slowly draining into the ground below or stored in the sub base for reuse, preventing pooling on the surface..
Capillia™ sub-base materials for SuDs are widely available. Thanks to its network of sites and locations, Lafarge provides:
- 0-40mm (Open Graded).
The sub-bases are laid in a 150mm-450mm thick layer under a variety of pavement offerings:
- Paving slab,
- Asphalt and concrete for parking spaces,
- Pedestrian foot paths,
- Pedestrian walking areas
- Roads for light vehicles.
The 2-6mm has dual purpose as this can also be used as brushing-in grit.
