Basement is the most sensitive part of house as it lies beneath the ground and therefore gets affected often by the pressure from expansive soil, resulting in cracks on internal walls of the underground room. If left unrepaired, the small crevices turn into larger cracks. Once the crevices get bigger, they allow radon gas, moisture, rainwater and melted snow water to get into the cellar.
Moisture infiltration in basement causes the growth of mould, mildew and fungus. Prolonged contact with water and moisture not only spoils the furniture and wood items but also makes clothes smell musty. Also, basement cracks arising due to expansive soil pressure pose a critical threat to the structural reliability and integrity of the property.
The only way to save the underground room and property from getting wet, damp and cracked is to waterproof the whole basement. This process of making a basement dry and watertight is known as basement waterproofing. Furthermore, there are 4 distinct methods of carrying out basement waterproofing. Below are details for each of the method.
Sealing of cracks
In this method, small leaking cracks or crevices in cellar floor and walls are sealed with waterproof coatings and sealants. However, for large structural cracks, the following method (injection repair) is used.
Crack injection repair
In this repair method, liquid polymer resin is injected into horizontal structural as well as leaking cracks in cellar floor and walls. Once the resin enters the crack, it completely seals off the crack and prevents it from seeping water and moisture.
This method is also known as water control solution for the reason that it controls or diverts the flow of water. In this method, weeping tiles are installed to direct the flow of water from the cellar walls to a sump pump system that further sends the accumulated water to storm sewer.
It involves excavation around house, application of hydraulic cement to support the affected portions and installation of drainage tiles. It is also known as positive side waterproofing for the reason that it directly takes care of the hydrostatic pressure and puts a stop to water infiltration.
Each method is different and requires distinct materials, techniques and tools that are properly operated by the technicians of DryShield, a specialized waterproofing company. The technicians of DryShield specialize in sealing and injecting cracks in underground room, installing weeping tile, sump pump & drainage tiles and carrying out interior and exterior basement waterproofing in Toronto. They know the very best ways to keep the basement dry, clean and watertight.
