Paving: Permeable Paving Permeable paving is a paved surface through which water is able to pass between the blocks. The benefits of a permeable paving system are: It assists stormwater drainage systems, natural breakdown of pollutants and water harvesting, while preventing soil erosion. The Bosun Waterwise Paver™ has four different installation techniques allowing for optional levels of permeability. With the correct design, water could either infiltrate the subgrade (ground), or be channelled to an underground storage facility, which has proved to be an extremely effective means of water harvesting.
Reality check It is far more expensive and requires much more skill to install permeable paving.
