Waterproofing is the process of treating masonry surfaces with chemical agents, to make them repel water. It is a common maintenance service which prolongs the life of masonry by minimizing its exposure to water damage. This is also a very effective way to stop existing leaks. Waterproofed masonry walls shed the water from wind driven rains, instead of absorbing it.

Any porous masonry surface (Brick, Block, and Limestone) will benefit from waterproofing.
