The best materials for stopping water from flowing are impermeable substances such as clay, concrete, and certain types of plastic or rubber. These materials have low permeability, meaning they do not allow water to pass through easily. In addition, geotextiles can be used to enhance drainage control, while steel or other metal barriers can also effectively block water flow. Properly designed and installed, these materials can create effective barriers against water infiltration.

Sand can stop water from flowing through by creating a barrier due to its dense and compact nature. The small particles in sand pack tightly together, which reduces the ability of water to pass through easily. The interlocking grains of sand create a barrier that slows down or prevents water from flowing through.
