Waterproofing
Waterproofing is defined as the treatment of a surface or structure to prevent the passage of water under hydrostatic pressure. Water exerts a pressure of 62.4 pounds of force per foot (1000 kg per meter) of depth. Therefore, water lying against a barrier exerts a steadily increasing pressure as the depth increases. The waterproofing treatment must keep the water from penetrating into the building interior.
