Expert Answer
Waterlogging and percolation are the major problems which occur due to overconcretisation of main roads as well as the internal roads. Lack of proper drainage system in place, waterlogging issue takes place. The interlocking of blocks allows only five percent of water to percolate, as compared to 40-45 percent of water with a mud track. With cement concretisation, there is minimal rainwater seepage resulting in a reduction in groundwater levels.
