Permeable pavements constructed using pavers from Island Block & Paving allow surface water to infiltrate through the pavers, into the sub base and sub grade below, to provide obvious benefits to the environment.
Permeable pavers are becoming more popular due to increasing water restrictions and drought conditions. Designers are now getting influenced by various authorities to use storm water management options that go beyond the conventional practice of collecting storm water run-off and draining it off site.
By installing a pavement using permeable pavers, water is encouraged to infiltrate through the pavement surface and substructure to the ground below. Permeable pavers are installed so a series of drainage holes are formed in the pavement surface. These drainage holes are filled with a small aggregate (2 - 5mm) to allow water to pass through the surface to the layers below. These layers then allow the water to infiltrate into the sub grade to be drained or stored to a suitable location.
Island Block & Paving have 2 types of permeable pavers available in 50mm and 80mm thickness.
Key Benefits of Permeable Paving:
- Environmentally responsible
- Reduces the load on existing drainage infrastructure
- Similar load bearing capacity as interlocking pavers
- Cost effective
- Reduces moisture evaporation from soil sub grade
- Better surface run off control
