Lift pits

Lift pits normally extend below ground / slab level and, therefore, like basements are susceptible to water ingress under hydrostatic pressure.

In new-build situations, lift pits are usually waterproofed externally using the same methods employed to waterproof newbuild basements.

In refurbishment situations, the waterproofing options are more limited than those available when refurbishing basements. This is primarily because working conditions are usually very confined. Cementitious materials such as Drybase Crystalline Active Tanking Slurry and Drybase Universal Mortar are therefore usually preferred over cavity drainage systems.
