Soakaways & Pervious Pavements

Dealing with excess rainwater in urban developments

Permeable paving allows for the passage of water from the surface into managed drainage, reducing the increasingly regular risk of flooding.

Using Enkadrain ensures a consistent flow volume of water, even under loading.

If the permeability of soil is low, you can use attenuation crates to store water before it drains, to reduce the risk of flooding at the surface. Enka-Tex forms a separation and filtration layer to stop soil or other particles that would reduce volume or the performance of the crates.

OUR SOLUTION

Soakaways and pervious pavements are examples of Sustainable Urban Drainage Systems (SUDS) that deal with excess rainwater in urban areas or proposed developments.

Use of soakaways

  • Often as drainage crates placed under a pavement.
  • Holds water as it permeates into the natural soil.
  • Can also create a pathway to a soil with higher permeability.
  • Enka-Tex is used to wrap the crates as a filter to stop the ingress of soil.
Use of soakaways
Pervious pavements

Pervious pavements

  • Control water running from surface to drain on hard-surfaced areas.
  • Often used for car parking areas or concrete cellar roofs.
  • Enkadrain drainage mat allows flow under substantial load.
  • Enkadrain's filtering fleece prevents any aggregate from entering the core.
Functions
  • Drainage.
  • Separation.
  • Filtration.
