Discover Resin Bound

Resin bound surfacing is a modern, durable, and aesthetically pleasing paving solution created by mixing natural 1-5mm aggregates with a clear two part polyurethane resin. This resin and stone mixture is then applied to a prepared base and hand-trowelled to form a smooth, seamless finish. It’s a popular choice for driveways, pathways, patios, and public spaces thanks to its attractive appearance and long-lasting performance.

Unlike loose gravel or traditional tarmac, resin bound driveways are fully bound, meaning every stone is coated in resin before being laid. This ensures a solid, stable surface that is both slip-resistant and highly durable. Purchasing your resin bound materials from Resin Mill over other suppliers ensures you have access to our advanced products, which guarantee the highest quality surfaces to ensure years of lasting beauty. 

A high-quality resin bound surface starts from the ground up...literally. The foundations and build-up beneath your resin bound installation are crucial for ensuring long-term durability, proper drainage, and a smooth, crack-free finish. Cutting corners at this stage can lead to costly issues down the line. To understand what goes into a professional resin bound job, check out the diagram below for a clear breakdown of each layer.

Our preferred resin bound build-up

Bound Base PRO is Resin Mill’s preferred base system for new resin bound driveways, paths and patios. It combines a single-part resin binder with carefully graded aggregates to create a stable, permeable base beneath the decorative resin bound surface.

Designed as an alternative to a traditional asphalt or concrete base course, the system uses 50kN reinforcement mesh above and below Bound Base PRO. A typical overlay time of 2 to 6 hours helps installers progress to the decorative finish, depending on temperature and site conditions.

Resin bound surface: 15 to 20mm

The decorative top layer combines natural aggregates with UV-stable resin to create the finished surface. The installation depth must suit the intended use and follow the decorative surface specification.

Reinforcement mesh: 50kN

A layer of 50kN reinforcement mesh sits between Bound Base PRO and the decorative resin bound surface. It works with the second mesh layer below the base to reinforce the system and improve crack resistance.

Bound Base PRO: 15 to 30mm

The permeable base course provides a stable foundation for the decorative surface. Pedestrian applications use 1–5mm aggregates at a finished depth of 15mm. Vehicle, heavy traffic and commercial applications use 6–10mm aggregates at 30mm.

Each batch combines 4.5kg of binder with 100kg of aggregate. All heavy traffic and commercial applications also require 5kg of Binding Quartz per batch.

Reinforcement mesh: 50kN

A second layer of 50kN reinforcement mesh sits beneath Bound Base PRO, over the prepared capping layer or sub-base. Both mesh layers are essential.

Order enough mesh for two layers, plus 10% extra for overlaps, offcuts and waste.

Capping layer: optional, up to 25mm

A compacted layer of suitable 5–10mm angular aggregate provides a level surface beneath the lower mesh.

Kit coverage assumes a capping layer is used. Without it, coverage will be approximately 10–15% lower. The product calculator does not adjust for this reduction.

MOT Type 3 sub-base: 150mm+

A properly compacted, free-draining aggregate sub-base supports the construction above. Its depth and drainage design must suit the ground conditions and intended traffic.

Geotextile membrane

A permeable separation layer helps prevent the subsoil and sub-base aggregate from mixing. This is separate from the two layers of reinforcement mesh.

Subsoil

The prepared ground supports the complete construction. Its stability, bearing capacity and drainage must be assessed before installation.
