Porous concrete is made using large aggregates with little to no fine aggregates. The concrete paste then coats the aggregates and allows water to pass through the concrete slab. Porous concrete is traditionally used in parking areas, areas with light traffic, residential streets, pedestrian walkways, and greenhouses. It is an important application for sustainable construction and is one of many low impact development techniques used by builders to In the presence of clayey soil, water can be percolated through providing borehole at every 1-2km with the help of drainage system. Water can be filtered and stored as the freshwater below the ground. We can also give direction to water specifically according to need. By providing the certain angle to the flaky aggregate water which gets drained will make its way to the slope going down towards the sewer line or any other drainage arrangement. This could be useful where soil strata have less water absorption capacity.
