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.

Resin Mill Resin Bound Pro (15–20mm)

• This is the top decorative and functional surface layer, made from natural
  aggregates bound together with a high-performance UV-stable polyurethane resin.
• It creates a smooth, durable, and aesthetically pleasing finish that is fully
  permeable, allowing water to drain through.
• Designed for pedestrian and light vehicular traffic, it offers slip resistance, low maintenance, and long-term resilience against weathering.

Resin Mill Crack Reduction Membrane (100kN strength)

• A heavy-duty, high-strength reinforcing membrane that acts as a flexible layer between the base and the resin surface.
• It helps prevent reflective cracking from movement or settlement in the sub-base
  or base layers from transferring to the resin surface.
• Made from polymer-based geogrid or geotextile material, it enhances the structural integrity of the system.

Asphalt AC10 or Porous Concrete (50–80mm)

• This is the structural base layer that supports the resin-bound surface, typically composed of either asphalt concrete (AC10) or open-textured porous concrete.
• It provides a stable, load-bearing platform while still allowing water to pass
  through if porous variants are used.
• The choice between AC10 and porous concrete depends on required strength,
  permeability, and site conditions.

MOT Type 3 or Similar (150–200mm)

• A sub-base layer made from crushed, graded aggregates with reduced fines content to improve permeability.
• It offers high load-bearing capacity and allows water to filter through to lower
  layers, making it ideal for SUDS-compliant systems.
• Commonly used in permeable paving setups, this layer supports the layers above while ensuring structural integrity and drainage.

Geotextile Membrane

• A permeable fabric layer placed between the subgrade and the sub-base to prevent soil migration and mixing with the aggregates.
• It acts as a filtration and separation layer, aiding long-term system performance
  and stability.
• Made from synthetic polymers such as polypropylene or polyester, it is rot-resistant and designed for ground contact.

Soil/Subgrade

• The native ground or prepared earth surface on which all other layers are built.
• Its role is to support the entire paving system; it must be compacted and assessed for bearing capacity and drainage suitability.
• Varies in composition depending on location, but typically includes clay, silt, sand, or combinations thereof.
