What is the difference between resin bound and resin bonded?

Despite having similar names, resin bound systems and resin bonded systems are completely different.

Both systems use resin and aggregates to form fixed surfaces, but the differences are numerous. This page will take you through the key differences between resin bound and resin bonded systems.

What is resin bound?

Resin bound is the fastest growing surfacing solution in the UK, and it is being embraced by landscapers, developers and contractors nationwide. It is a system of laying a hardwearing course of mixed resin onto a new or existing bitmac or concrete base.


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.

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. Our guide to SUDS compliance can tell you more about this.


We offer the widest range of aggregate colours in the UK, giving you near limitless design possibilities. A resin bound system is precise and flexible, allowing you to create stunning designs and shapes that would not be possible with other surface solutions.

At Derbyshire Specialist Aggregates, we believe a resin bound system is the highest quality and most durable aggregate-based surface solution currently available. No other system offers the same range of strengths, resistances, structural and aesthetic benefits as resin bound.

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.

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. A resin bonded system is therefore not a SUDS compliant solution.
