Sustainable Drainage System (SuDS) Aggregate

Soils and Stone provide permeable sub-base aggregates and laying course sands for use on roadways, hard standings or driveways where a Sustainable Drainage System (SuDS) is required.  SuDS aggregates allow surface water to permeate through the sub-base into the underlying ground.

 

Why is SuDS important?

 

With increasing pressure on further urban development planners and developers alike need to take account of how water run-off is managed.

 

Using SuDS can

 

  • avoid excess water entering into the existing sewer systems
  • allow a more controlled draining away of water
  • help reduce and even avoid flash flooding
  • collect and clean storm water

 

 

How does SuDS work?

 

 

Angular in nature, when compacted down, the SuDS aggregate locks together to create a strong, stable and porous sub-base which allows water to be stored and then gradually released.   This is topped off with a laying course and permeable paving.

 

Available in limestone or granite, this material contains no fines.

 

Soils and Stone can supply 2 – 6mm, 4 – 20mm, 10 – 63mm permeable sub-base aggregate nationwide, in the loose or via industry standard bulk bags.  Our delivery options include grab, tipper or hiab crane off-load.  Call our team today to discuss your requirement.

2-6mm SuDS Aggregate

Our 2 – 6mm is an ideal top layer of any SuDS solutions.

 

Typically, a 50mm top bedding layer of 2 – 6 mm SuDS is placed on larger 250mm course of 4 – 20mm SuDS aggregate prior to laying permeable block paving.  This combination will allow excess water to slowly drain into the underlying ground and water systems.

4 - 20mm SuDS Aggregate

Our 4 – 20mm SuDS aggregate is an ideal upper sub base material when creating any permeable solution.   It’s larger size means it is often used as a base layer to our 2 – 6mm SuDs aggregate.  In addition it provides increased void space allowing even water storage.
