Basements

Basement waterproofing should always be considered as a 3-dimensional problem. It is important to establish whether the system is required to provide or has failed to provide resistance to water pressure and whether additional controls on water vapour are also required (see Georgian basements).

Failures can result from a number of situations, including leaks, poor installation, damp penetration (see Typical failures).

The types of system available are tanking, integral, or drained (see Types of systems).
