Risks of not waterproofing the foundation
Structural damage: Foundation has wet soil underneath it, which can shift due to swelling or loss of strength. A dry foundation is critical since these shifts harm the building's structural integrity. If the foundation is not waterproofed, the changes can result in cracks in the floor and walls, which can further lead to expensive repairs.
Mold and mildew: Besides, dampness in the foundation presents a conducive environment for the growth of mildew and mold. While mold is a severe health hazard that can cause respiratory and skin problems, it can also lead to unpleasant smell in basement and surroundings.
Poor water flows: Conventional concrete may keep out water if there are no cracks in the foundation, but it is not entirely waterproof. Water vapor from damp soil can penetrate easily into the concrete. Preventing water from traversing the pavement and channeling it away from the foundation is crucial to maintaining structural integrity.
If adequate channels are not provided for water drainage, there can be ongoing problems with leaks and water seepage.
