‘Occasionally perceived as a precast concrete block, in truth it is far from that. GRASSCRETE is essentially a cast-on-site cellular reinforced concrete system with voids created by plastic formers.
Such a construction offers significant structural advantages over precast concrete and plastic paving systems.
GRASSCRETE is essentially a cellular reinforced concrete slab, the cells being created by casting around plastic void formers.
The plastic former, manufactured from recycled materials is the culmination of many years of study which has perfected the shape of the pocket and the form and draw of the vacuum forming process. It provides crucially, the strength to accept live concrete loads, yet is thin enough to enable the tops to be easily melted to reveal the voids.
Structural analysis of the finished concrete section is based upon the bending moment of the mesh reinforcement contained within the slab, relatively to slab depth, contact area with base and an assumed allowable ground bearing of 45kN/m2 for its base. By using combinations of depth and different mesh types, the system can be tailored to provide the most economical solution.’
