What is waterproofing?
Waterproofing is needed anytime structure is located below grade. Your walls can be susceptible to basement leaks through several different ways, causing moisture, mold and damage to your property. Exterior waterproofing prevents water from entering foundation walls from the outside by hydrostatic pressure or cracks in the foundation, and is the only adequate method to prevent water penetration. This may be augmented by new or enhanced weeping systems and sump pumps to move water away from the foundation walls.
How does that differ from Interior Waterproofing?
Interior waterproofing is for minor dampness due to condensation and is usually addressed by coatings or coverings. In extreme cases where the exterior walls cannot be accessed, internal drainage and weeping systems may be required.
