Sealing a wall on the inside traps water within the wall and actually speeds up the deterioration of the wall, which could lead to foundation walls bowing and serious structural damage.
Water concealed below grade can get under the footings in a foundation, and destabilize the structural integrity of your home or business. This can lead to cracked foundation walls and footings, and very costly repairs. Standing water and heavy moisture behind finished walls can lead to an infestation of mould, mildew and fungus on the joists, studs, carpet and baseboards.
Not only can mould lead to wood-rot and costly repairs, the spores that can be released in the air can be quite damaging to your health. The key to controlling mould growth is keeping our environments dry and by maintaining a low relative humidity.
Waterproofing your exterior foundation will prevent any water from damaging your home and save you thousands of dollars in the long run.
