The foundation contractor might have installed a bordering drain system while the building basement of your house and waterproofed the walls. But sometimes contractors, instead of using waterproofing methods, use damp proofing methods, which cannot resist ground water. In fact damp proof sprays are not as thick and effective as waterproofing materials. Another reason your home may need waterproofing is improper installation of perimeter drains around it. Some of the contractors, instead of excavating the soil for proper drainage system, use corrugated pipe to build a perimeter drain.
You can recognize the need of exterior waterproofing in your home is you observe following internal and external signs.
- Peeling of paint
- Buckling of wall or panel covering
- Musty smell
- Damp walls or/and floor
- Cracks on walls or/and floors
- Weakened baseboards
- Mildews or molds on walls
- Windows and doors are hard to open and close
- Non-working or clogged drains in stairwell region
- Cracks in foundation
- Cracks on external bricks of the home
In order to waterproof your home externally, most of the professional waterproofing and plumbing service providers will excavate around your home to prepare its foundation by exposing it properly. The professional will then wash the walls containing the crack with a concrete sealing solution to close the sources of dampness and wetness in your basement.
