Resin Bound and Resin Bonded Aggregates

What is the difference between resin bound and resin bonded?

Both systems use resin and aggregates to form fixed surfaces, but the differences are how water permeates through the surface.

How does resin bound work?

  • The dried aggregates are mixed with the resin. The resulting material is trowelled onto the base for a smooth, flat finish with no loose gravel.
  • The porous surface of a resin bound system allows water to pass through into the ground beneath.

Is resin bound permeable?

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.

What is resin bonded?

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.

Is resin bonded permeable?

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.
