What are Permeable Systems?
Resin bound gravel surfaces allow water to drain through them. Because the gravel (or aggregate) is bound in resin it remains porous. That means the surface is what is termed as SUDS compliant (Sustainable Urban Drainage Systems).
The water drains through the surface like it would through a natural grass surface and then flows into the water table. This is an environmentally friendly option for surfacing and SUDS compliance reduces the risk of flooding, even more so when used on large scale projects.
The Environment Agency have, for a while, encouraged resin bound surfaces to help tackle the growing threat of flooding in many urban areas. This is why it’s such a great surface for parks, play areas, large drives, paths and playgrounds.
