Basement Waterproofing Tips
There are several reasons why a basement develops cracks and holes such as earthquakes, constant pressure from the surrounding soil on the basement walls and an aging house. Over time, the structure will require repeat finishes and touches to ensure that water does not come in and all items and supporting components are properly maintained and kept. It's important to consider the different areas and methods on how to waterproof a basement to prolong the house's life.
1. Waterproof the walls with or without cracks. People who wish to know how to waterproof a basement waterproofing paints and compounds available to apply on the walls of the basement which will seal the area and prevent water from seeping in. A wet basement is generally triggered by cracks and holes on the basement floors and walls and should be filled using special mixes and pastes. Very small cracks measuring no more than a few millimetres can be patched first before putting in the mix. Use epoxy formula for filling in small cracks then coat the surface afterwards with waterproofing formula. Bigger jobs will require individuals to mix a unique mortar to fill in the gaps before coating the surface.
2. Use the mortar. The mortar is first mixed by the homeowner or professional and then used to fill in the holes and cracks to learn how to waterproof a basement.

3. Chipping a dovetail groove. A dovetail groove chipping with the help of a hammer and chisel might be required along the cracks. Making the crack bigger will make it easier to add mortar and repair. The same technique can be used to fix holes. The person will know if the groove has been made the right way if the mortar sticks and seals the area effectively. The type of groove created makes it easier for mortar to stick.

5. Getting help. Some people can learn how to waterproof a basement on their own or with an assistant. When fixing the surrounding soil outside, beginners are better off hiring a professional and observing how it's done the first time. It will take professional assessment and methods to adequately create the needed slope and identify how much earth should be taken out to relieve the pressure for waterproofing Toronto.
