Invisible Structure's Grasspave2 is an exciting "invisible' porous paving technology that unite eco sturcture engineering with horticultural methods to allow living turf grasses to be used as traffic bearing surfaces. It comprises a specifically engineered porous base supporting a fully interlocked flexible matrix. This maintains soil aeration by preventing deadly compaction. Surface integrity is maintained by preventing lateral migration of root zone medium. Hence it enables the grass root system to remain intact and functional, allowing continous healthy turf under traffic.Invisible Structure's high percolation rate of the Grasspave2 system reduces storm water runoff while promoting ground water recharge. It creates a free draining surface, which prevents the damage commonly seen when drainage is poor.
