PERMEABLE BLOCK PAVING

COST EFFECTIVE SOLUTION

Recent extreme weather events have highlighted the need to manage the water flow.

It has been recognised that impermeable surfaces contribute to the accelerated water flow into the drains, and a solution to this problem has been the development of CBPP (Concrete Block Permeable Paving). With CBPP surface water rapidly disperses down into the substrate below - which acts as a water reservoir during extreme weather conditions, thus reducing the pressure on the drainage system.

A properly designed and implemented SUDS system has been shown to be a cost effective alternative to traditional drainage systems.

ADVANTAGES OF PERMEABLE PAVING

• Lower peak flows to the watercourse, which reduces risk of flooding downstream.
• Compliance with PPG25 'Development and Fold Risks.'
• Cost effective, compared to gulley’s, pipework and associated products that are required for conventional drainage systems.
• Maintenance is minimal.
• Like standard paving, they can be uplifted and re-instated without any detrimental affect. This means it can be re-laid leaving the area without any ugly scarring. Also giving a saving in using the existing materials and not having to dispose of the old surface and purchase further surfacing materials.
• Improved water quality, filters the waterflow, removing heavy metal and hydrocarbons at source.
• Able to handle direct drainage from roof water.
• Reduces need for further retention in system.
