All basements, even those with basic basement waterproofing in Mississauga, can still develop hairline cracks when they are below grade making them wet. These cracks can become worse when there is a buildup of snow or water against them. You can also have flooding for other reasons some of which include debris in eaves troughs and downspouts and also in the window wells.
Before calling in a professional to check the basement waterproofing, be sure to check the eaves troughs and downspouts for any debris that might be blocking them. Be sure the downspouts extend at least three feet away from the foundation and the grade around the home should be sloped away from the foundation. Also check window wells and make sure they are free of any debris.
For basement waterproofing in Mississauga, all window wells should have a drain in order to prevent water from seeping into the basement. This drain will carry the water away from the foundation wall.
When basements are constructed, the window wells are installed below grade in Mississauga. This makes them very open to flooding from the trough spillover, heavy rain, snow buildup or a collection of debris. When the window well floods, the water goes into the basement but a plastic well cover helps to keep debris and water out of the window wells and helps prevent flooding.
When doing basement waterproofing, either outside or inside weeping tile can be used. The outside weeping tile prevents the ground water from building up under the basement and carries away any excess water from the foundation wall.
All basements in Mississauga that are built below grade must have perimeter weeping tile. This weeping tile is part of basement waterproofing and must also be done according to the building codes. The weeping tile is strong, light, round, plastic hose with about a four inch diameter.
The weeping tile for waterproofing is designed to carry water away from the foundation to a storm drain or sump box. To install outside weeping tile, the site must first be excavated and then have the footings installed. Then the foundationwalls are poured. The weeping tile is placed one to two feet below the finished floor, on the outside, and next to the footing.
To complete the basement waterproofing with outside weeping tile, it is covered with one to two feet of ¾” gravel. Then damp proofing and drainage board is applied to the perimeter foundation wall. The whole are is then backfilled to the grade level.
Basement waterproofing, when done with inside weeping tile, will give a 100% waterproof basement. If there is a block foundation, there will be cavities at either end of the concrete block to help contained water to sink into the ground. With a poured concrete foundation, the same process applies when installing the inside weeping tile.
Sump pumps are used in basement waterproofing to gather excessive ground water and send it to a ditch at the front or rear of the house. The sump pump has an automatic shut off in order to keep the water at the proper level and can also have an alarm system that warns you when water is getting too high too fast. A submersible sump pump will pump the water away from your foundation.
When there is basement flooding due to a crack in the foundation, it must be repaired in order to maintain the waterproofing. The crack is best repaired from the outside and is usually done with digging by hand to expose the crack. This is done the same way with both poured concrete foundations and concrete block foundations.
