40 mm Aggregate

40mm stone aggregate is a heavy-duty material engineered for maximum load-bearing capacity and structural stabilization in massive infrastructure projects. Its large, sharply angular profile creates high-friction interlocking, making it the ideal choice for railway ballast, bridge abutments, and industrial foundations. The significant voids between the stones provide exceptional porosity, facilitating rapid water drainage in soak pits and trench lining to prevent waterlogging. Beyond structural support, its sheer weight and size offer a rigid, erosion-resistant solution for temporary access roads and heavy-vehicle hardstands.
