Rock Crete Sub Base – Durable, Permeable Foundation for Resin Bound Surfaces

A strong surface starts with a strong foundation, and Rock Crete Sub Base is designed to deliver exactly that. Engineered specifically for resin bound driveways, patios, pathways, and public spaces, Rock Crete provides a durable, permeable, and flexible base system that supports long-term performance from the ground up.

Unlike traditional sub bases, Rock Crete is created to work seamlessly with resin bound surfacing systems, helping form a reliable and stable foundation that improves overall strength, drainage, and longevity. Its 100% permeable structure allows water to drain naturally through the surface, making it an excellent choice for projects that require a SuDS-compliant, drainage-friendly solution.

Why Choose Rock Crete?

  • Strong and reliable for both pedestrian and vehicular traffic
  • 100% permeable to help prevent standing water
  • Flexible and durable for long-lasting performance
  • Eco-friendly and designed with sustainability in mind
  • Ideal for driveways, footpaths, patios, and public spaces
  • A smarter alternative to traditional tarmac and concrete-based foundations

Built for Performance

Rock Crete is more than just a sub base - it is a high-performance foundation system developed to improve the success of the entire installation. With its combination of strength, permeability, and easy installation, it helps create resin bound surfaces that are more stable, more functional, and built to last.

600% Higher Flexural Strength Compared to Asphalt

Provides significantly greater flexibility and durability, making it a superior choice for high‑traffic and heavy‑duty applications.

Benefits of Rock Crete

100% Permeable

Rock Crete is designed to allow water to drain naturally through the system, helping reduce standing water, improve drainage, and support SuDS-compliant installations. This makes it a smart choice for projects where permeability and long-term surface performance matter.

Strong & Reliable

Built for both pedestrian and vehicular traffic, Rock Crete provides a dependable sub-base that delivers the strength and stability needed for driveways, pathways, patios, and public spaces. The page also describes it as suitable for vehicle weights and tracked areas.

Flexible & Long-Lasting

Unlike rigid traditional bases, Rock Crete is designed to be flexible as well as durable, helping create a more resilient foundation for resin bound systems. Resin Rock also describes it as having up to 600% higher flexural strength than asphalt, reinforcing its durability under demanding conditions.

Monolithic Bond for Better Performance

When installed within the recommended intercoat period, Rock Crete forms a monolithic bond with the resin surface layer. This creates a more unified system that improves overall strength, stability, and long-term performance compared with traditional foundations not designed for resin bound applications.

Quick & Efficient Installation

Rock Crete is presented as a faster, more efficient solution that can be installed in just one day, helping reduce disruption on site and speed up project completion. The page also highlights that it can avoid the need for traditional heavy base construction.

No Tarmac or Concrete Required

Because Rock Crete is engineered specifically for resin bound systems, it can remove the need for conventional tarmac or concrete bases. That means a cleaner, more efficient installation process with a system built specifically for resin bound performance.

Eco-Friendly Solution

Rock Crete is described as an eco-friendly foundation system made with a lower environmental impact in mind, including the use of selected recycled aggregate in its composition.

Rock Crete Composition & Features
