Abstract: A system is provided that improves basement sustainability in regards to a building's sub-ground level foundation hydrostatic pressure modulation, waterproofing and interior air control and that yields sustained clean and dry interior space.

Abstract: A temporary safety box for assistance in excavation of an associated below grade foundation wall is placed in an associated trench located adjacent the associated foundation wall. The safety box comprises a wall member including an inner surface, an outer surface, a first end face and a second end face. The inner surface faces the associated foundation wall and includes a reinforcing element for providing strength and rigidity to the wall member. The outer surface abuts a wall of the associated trench and is configured to assist in removal of the safety box from the associated trench. The first and second end faces abut the associated foundation wall. The safety box and the associated foundation wall together substantially surround a worker in the associated trench to protect the worker from excavated debris.
