What Is Involved In Exterior Waterproofing Of My Home


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.

Internal 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

External signs

  • 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.

After washing the walls with concrete solution the plumber will wash them with a sealant like damp proofing compound so that moisture can surely not enter into your basement to keep it smelling and damp.

Next he will install a polyethylene plastic membrane based waterproofing material on the exterior walls. It will protect your walls externally from the flow of ground water to ensure the safety of your walls from the unwanted damages from water.

He can also install weeping tiles and connect them with drainage system available there to collect and remove the unwanted ground water efficiently.

After completing the whole exterior waterproofing process your plumber will bury the recently waterproofed foundation of your home again. The surrounding of your home will be graded again to ensure that rainwater build-ups can be avoided by maintaining the grade slopes away from the walls.

Keep the walls of your home safe from unwanted damages due to flowing ground water or seepage and leaks from rainy weather. Call a plumber to waterproof your home so you can enjoy every part, including the basement.
