Key Challenges

The designers had to choose between a hard paved surfacing or select a paving system that is more environmentally in keeping with the surrounding landscape.

A porous paving system using a recycled plastic gravel block was specified which would remove the need for conventional drainage systems and to provide an aesthetically pleasing finish to the car park.

Solution

The chosen solution was to design the sports pitches in such a way so as to attenuate the rain water within the aggregate sub-base of the pitches. Rainfall falling on the sports pitches percolates through the porous surfaces into the open voided aggregate sub-base below.

The client and contractor contacted Infra Green and decide to choose Slimblock 50 as their preferred product. The 500mm x 500mm x 50mm Slimblock units were selected for the following reasons:

• Ease of installation
• Load bearing capacity
• Aesthetic appearance
• Mechanical interlocking and durability.
