Both systems use resin and aggregates to form fixed surfaces, but the differences are how water permeates through the surface.
|Description||Resin Bound||Resin Bonded|
Yes, the porous surface of a resin bound system allows water to pass through to the ground beneath. Providing it is laid onto a permeable base, a resin bound system is a SUDS compliant external surfacing solution.
Resin bonded gravel is a system where the resin is spread across the base, and the aggregate is scattered into it. Most of the aggregate will adhere to the resin, while some will remain loose. This gives the appearance of loose gravel, with less aggregates to move or replace.
No, because the aggregates are scattered on to a complete layer of resin, water cannot pass through; this means a resin bonded system is not porous.
