A basement may contain habitable space, although more commonly the basement area of a multi-storey structure is set aside for parking and utility rooms. This is in contrast to the foundation of the building and differs in some respects from a structural service pit such as a lift well. The substructure will be in contact with the surrounding earth. There will be penetrations for ventilation and other services.
The great basement challenge is waterproofing.
Not only is it crucial to keep the usable space dry, it is also imperative to maintain the integrity of the structure itself.
What are the risks?
Is there a process that will protect the structure from the outset?
Waterproofing structures below grade is a very broad subject. To focus on the concrete itself, the construction methods vary to some degree, and there are a variety of approaches to its protection from moisture. For optimum results, controlling concrete’s porosity will provide long-term protection for the structure.
Ideally, concrete’s porosity should be permanently sealed …
… against moisture movement within the matrix. This provides a barrier against seepage which is not dependent on membranes or tanking.
