This will not work for a couple of reasons.
How to lay permeable block paving. In free draining applications a suitable geotextile should be placed at formation level overlapping joints by 300mm below the drainage aggregate sub base. Concrete block permeable paving cbpp relies on the use of modified blocks and selected free draining aggregates to deal with surface water at source rather than send it into the already overworked sewer systems of our towns and cities. Always begin laying block paving from the bottom of a slope preferably starting from a right angle or a straight edge.
Concrete block permeable paving cbpp differs from conventional block paving because it allows water to soak through the driveway preventing water from amassing and flooding. The following diagrammatic instruction for laying block paving is intended to be used in conjunction with the detailed methodology given on the flexible construction page. Place the blocks on top of the laying course ensuring blocks are around 10 15mm above the desired finished level.
Permeable pavers are used to allow rainwater to be absorbed into the ground rather than run off into the storm drain system where it can contaminate local water supplies and interrupt the natural water cycle. This page details the construction methods and materials for a typical cbpp project using forterra formpave. Using a permeable or porous paving system has many advantages over and above being environmentally conscious including durability stability and ease of maintenance repair.
