Waterproofing 101: Diverting Water Away From Home

One of the most effective ways to waterproof your home is actually to divert water away from your foundations. Poor drainage and surface run off can cause water to pool near your home, and eventually let water into your basement. This can be further perpetuated if there are improper gradings on the site.


  • Make sure downsprouts and gutters carry water effectively away from your home. You can attach extensions to the end of downsprouts to carry water a safe 10 to 15 feet away from your home.
  • The grading around your home should ensure that water flows away from the structure, and should be sloped for at least 10 to 15 feet. Low spots that collect water should be evened out, or french drains installed to carry water away.

Waterproofing 101: Interior Drainage & Water Control

Interior drainage and water control systems are one of the best treatments for a wet basement, and are highly cost effective. The basic approach is as follows:

  • Dig a trench around the interior basement wall.
  • Install a drain that diverts water outside of your home.
  • The drain can sometimes be connected to a sump pump system, to pump the water outside.
  • The drainage and trench are covered up.

Waterproofing 101: Filling Cracks & Gaps In Walls

This is one of the ways in which you can prevent leakages in your basement. Cracks and gaps in the walls of your foundations can be a major point of entry for water. As well as installing interior drainage, defects in the concrete should be filled in with an adhesive that helps to support the structure of your home. You can do this using a sealant or hydraulic concrete.

Waterproofing 101: Waterproofing Interior Walls

An effective way to solve your wet basement, is to waterproof the interior walls. Professionals tend to do this with delta membrane, but as a home treatment you can apply sodium silicate, or waterproof paint. This stops water from coming through as damp, and combined with drainage can stop your basement from getting too wet. Applying the waterproof paint is pretty much the same as applying any paint, whereas the silicon takes more precaution.

  • Clean the walls to expose the bare concrete.
  • Apply a thick coat, taking care not to get it on your skin.
  • Wait 20 minutes, then apply another coat. Three or four coats of paint is preferable.

Waterproofing 101: Exterior Waterproofing

Exterior waterproofing is one of the most troublesome solutions to tackle on your own, and if you get it wrong it could be tragic! You have to excavate down to the footings of your foundations on the outside of your house, and then install waterproof membranes to the walls. Then, you install drainage systems to carry water away from your foundation, and bring the levels back up to flush.

Put simply, this is one type of basement waterproofing treatment that you should leave to the professionals.

Waterproofing 101: Is It Better To Call In The Pros?

For exterior waterproofing, it is always recommended that you call in the professionals. The treatment requires heavy work, and needs to be conducted accurately in order that a decent result be achieved. Failing to do it well could be very costly, as excavation would again be required.

The rest really depends on the scale of the problem, and how competent you feel tackling it on your own. There are, however, many advantages to working with professionals like Direct Waterproofing.
