10-20 mm SuDS Gravel Mulch (Cotswold Chippings)

10-20 mm Cotswold chippings are a permeable angular limestone aggregate suitable for use as SuDS gravel mulch in rain gardens, swales, and bioretention areas.

Its porous structure facilitates water infiltration, reducing surface runoff and aiding natural drainage. The chippings also contribute to erosion control by stabilising soil in SuDS features.

As a mulch layer, it helps regulate soil moisture levels and suppresses weed growth, supporting low-maintenance landscaping.

It’s durability and resistance to compaction ensure long-term performance in sustainable urban drainage applications.
