    The document provides a guide for the level of protection needed for different types of basement usage based on how dry the environment needs to be. It lists 4 grades of protection from 1-4 with grade 1 requiring some seepage protection and grade 4 requiring a totally dry environment. For each grade it provides comments on groundwater, acceptable usage, and the type of construction recommended according to British standards for reinforced concrete and damp proof membranes.
