Product Details

CBGM is a Hydraulically Bound Mixture (HBM) produced by blending quality aggregates with cement and water, creating a robust, uniformly bound material that provides a stable and durable foundation.

This engineered HBM offers greater stiffness and bearing capacity than traditional unbound sub‑bases, enabling reduced build‑up thicknesses and faster construction programmes.

CBGM can be installed using conventional paving equipment and is typically trafficked within 24 hours, making it well suited to projects where time and performance are critical.

The material is suitable for use in sub‑base and capping layers, as a replacement for base and binder asphalts, and in adoptable roads, haul roads, laydown areas, car parks, and footpaths.

Produced to SHW Series 800 / CC 201 and BS EN 14227‑1 standards, HBMs provide a compliant, sustainable, and reliable solution for demanding infrastructure works.

Product supply may be subject to geographic availability.
