CellPave™ GT40 Gravel Reinforcement Grid

CellPave™ GT40 is a high-performance interlocking cellular paving system engineered for demanding ground reinforcement applications where strength, permeability, and sustainability are essential. Manufactured in the UK from 100% recycled, UV-stabilised polypropylene/polyethylene, this 40mm gravel reinforcement grid delivers exceptional load-bearing performance while maintaining a fully permeable surface that meets SuDS (Sustainable Urban Drainage Systems) standards.

Independently certified by Lloyd’s British, CellPave GT40 achieves a compressive strength of over 810 tonnes/m² when infilled with angular gravel, making it one of the strongest 40mm cellular paving solutions available. Even unfilled, the grid maintains excellent structural integrity, ensuring long-term durability under repeated vehicle loading. Its anti-slip nodules enhance traction for vehicles and pedestrians, while the integrated anti-migration lattice prevents gravel loss and rutting, even on sloped or heavily trafficked surfaces.

Designed for efficiency, the innovative push-fit “walk-in” locking system allows installation rates of up to 100m² per hour. Perfect for estates, farms, stables, golf courses, and commercial projects, CellPave GT40 creates a low-maintenance, visually appealing surface that blends seamlessly into rural, heritage, and landscaped environments. Whether reinforcing overflow parking, estate roads, or pedestrian areas, this system combines extreme strength, sustainability, and simplicity for lasting performance.
