The EcoGrid system reinforces or “paves” the ground surface without sealing it. This means that even with high surface loads (800 t2 / m, depending on soil type) the rainwater/surface water can easily infiltrate the ground, usually without additional complex drainage elements. This also means in some cases (depending on government) there is no storm water tax per surface area. Because the EcoGrid system can be filled with different materials it allows total design freedom for landscaping. EcoGrid ensures safe access and parking/turning of emergency vehicles.
Once the surface has been excavated and prepared, the grids are swiftly laid on the screed level, curves are formed with our unique curving piece. A retaining edge strip and secure anchor system is available to form a barrier, impeding the travelling of infill material away from the surface (only necessary if you want to ’override’ the grid surface with stone. It should be noted that the fill material should be sharp angular stone and range from 10-20mm. River bed or rounded stone can be used but this material doses not lock together as well as angular.
We also have a unique curving piece to ensure continuous curving of grid based surfaces without the need for cutting. We have a variety of UV stable markers to delineate parking bays.
A drainage layer is laid, the depth of which corresponds to the type of traffic which will access the surface. This is generally classed as type3 reduced fines. This means 20mm stone mixed with smaller stones to create a firm foundation but the difference between this and type 2 is that the ‘dust’ content is removed which makes the sub-base as permeable as possible. It is also possible to use clean 10-20mm stone.
