At Monty Mix Concrete, we supply specialist road foam concrete mixes designed for highway, roadworks, and infrastructure projects. We have supplied thousands of m3 of it! Foam concrete is a lightweight, free-flowing, and versatile material that is widely used across the road construction sector for its speed of placement and long-term performance.
Foam concrete is produced by mixing cement paste or slurry with a stable pre-formed foam. The result is a lightweight concrete with excellent flow properties, making it easy to place and self-compacting. For roadworks, it provides a cost-effective and efficient solution for a variety of applications.
