Underground waterproofing refers to the process of preventing water from penetrating underground structures, such as basements, tunnels, and foundations. Underground structures are particularly susceptible to water intrusion due to the high pressure exerted by the surrounding soil and groundwater.
There are several methods of underground waterproofing, including:
Cementitious Waterproofing: This involves the application of a cement-based waterproofing coating to the surface of the underground structure to create a barrier against water.
PVC Waterproofing: This involves the application of a PVC-based waterproofing membrane to the surface of the underground structure.
Bituminous Waterproofing: This involves the application of a bitumen-based waterproofing membrane to the surface of the underground structure.
Liquid Applied Membranes: This involves the application of a liquid waterproofing membrane, such as polyurethane or epoxy, to the surface of the underground structure.
The choice of underground waterproofing method depends on several factors, including the type of underground structure, the surrounding soil and water conditions, and the budget. It is important to consult with a professional waterproofing contractor to determine the best method for your specific needs.
