To make a waterproof basement in your Toronto house vertical and horizontal waterproofing is used. In the first case an insulating interlayer is made between foundation walls and the environment, in the second case the drainage system is built that drains water from the building.
Basement waterproofing is organized in several cases:
If your house is built on clayey soil, loamy soil or any other soil with sandy interlayer;
There are deposits of compact soil at the bottom of the foundation pit and there is no surface water outflow and it leads to the rising of water level.
Basement waterproofing is the whole complex of works that includes the protection of floor, external and internal walls. In order to get absolutely waterproofing basement, the floor must be damp-proofed even in the case when soil waters are lower than the water level. If you don’t know what you are doing, it is best to hire Toronto basement waterproofing experts to help you out.
As a rule it’s enough to coat the floor with bitumen to prevent water penetration from below. If ground waters are higher than the basement foundation, the floor is covered with rich clay and cement plaster. After drying up it is papered by hydrophobic sheets. From above the foundation is covered with liquid bitumen or with polymer-bitumen mastic.
Next step of the basement waterproofing construction is wall protection. They can be plastered with hydrophobic materials, and hydrophobic sheets cam be stuck over the top. The joints can be closed up with the help of liquid polymers or bitumen.
The external walls of the basement and the foundation are protected by the same method. Besides hydrophobic plaster and roll materials, special waterproofing paint can be used here. The pain on rubber basis gained great popularity. It is elastic, watertight and easy in use. But there is one important moment: you will get waterproofed basement only in case if you before hydra isolating materials processing will clean all the surfaces from the dust, dirt and fat stains.
It is very important to choose right hydrophobic formula that corresponds to the following conditions: the level of ground waters bedding, type of the soil, material of the walls and the foundation. If you want to construct a waterproofing basement that is situated lower than the soil waters level, you need to use water-resistant and crack-resisting materials. Contemporary building market offers hundreds of waterproofing materials (plastic, penetron, calmatron). All of them have different level of protection. Before buying please, examine their characteristics carefully.
