Grasspave2 was specified in the design by the City of Hamilton and installed by CRL Campbell. Designed to withstand heavy vehicle loading and permit rainwater percolation, Grasspave2 also provides a greener appearance compared to impermeable surfaces, such as asphalt and concrete. Prior to installing the rolls of Grasspave2, CRL Campbell prepared the subgrade, followed by placing and compacting the road base course with granular ‘A’ material. Hydrogrow, a mixture of polymer and fertilizer supplied with Grasspave2, was applied over the road base. Rolls of Grasspave2, which are 2m x 20m in length, were unrolled with the side hole fasteners aligned and connected with the side pegs of adjacent rolls. The cells were then filled with clean sharp concrete sand using rakes followed by hydroseeding. A total of 2,350sqm of Grasspave2 was installed. Within a few days, the root system began to establish itself with the grid. It is recommended that there is no traffic loading on the grass until approximately a couple of mowings after installation. Manufactured from 100% recycled flexible HDPE resin with UV inhibitors, Grasspave2 withstands repeated freeze-thaw cycles and continuous subzero temperatures without cracking. Additionally, HDPE can resist aggressive chemicals such as road salts, motor oils and fuels. Combined with a standard compacted road base material and sand that fill the cells, Grasspave2 can support 15,940psi of loading.
