includes the sealing and prevention of water seepage, condensation, and moisture into your basement or crawlspace. Different materials and methods are available to coat your basement and seal off the source of water seepages. Depending upon the location of your residential unit and the cause of seepage, our waterproofing company
can suggest several waterproofing basement methods. Understand the ways and choose wisely. Exterior waterproofing method:
An exterior waterproofing
method is a long-lasting approach to coating your basement walls and prevents complete water leakages from or inside the basement walls. Exterior waterproofing is commonly possible during the construction of commercial or residential units. This process is long and often requires heavy machinery and tools. However, manual excavation might be performed if the space is limited for a machine. Therefore, you need to hire a professional, experienced, trustworthy service for exterior waterproofing.
The process involves the excavation of the foundation around the basement of the building. The trench dug by the excavator removes the dirt from the surrounding foundation wall and creates a pathway to allow the water to flow away from the foundation. Once the soil is removed surrounding the building, the exposed foundation walls are supposed to be wiped with steel brushes and the coating applied to the basement walls. After the line is cleaned and dried, the coating is applied on the wall to cover the entire foundation wall. The coat seals off the walls permanently, and the leakages cannot occur as long as the building is there. The coating creates a waterproof barrier and prevents water seepage. After this, gravel is laid into the trench. Our technicians ensure that the process of gravel installation is even and does not damage the coating. We also install the weeping tiles. Weeping tiles are porous pipes of approximately 4 inches that redirect and discharge water from the underground. The tile designed like slits is effective for taking the water away from the underground. After the gravel is poured and weeping tiles are placed appropriately, then we backfill the whole trench surrounding the foundation wall. After the complete process, we compact the ground. Compacting refers to applying pressure on the soil or ground to restore the original landscape. Exterior waterproofing is a long-lasting method. The steps in the process ensure that the water does not seep into the basement and prevents flooding of the basement as long as the building is standing. Interior waterproofing method:
Interior waterproofing includes installing a system that channels away the water that leaks in the basement. Interior drainage installation or interior vapor barriers are the two ways of interior waterproofing the basement. The interior waterproofing system prevents the flow of water inside the basements and removes the water before it even touches the floor slab. In interior water control, we dig a trench of about 6 to 10 inches alongside the leaking foundation wall
. After digging a trench, we install a perforated weeping tile pipe. The weeping tile channels away the water from the underground to the outside. The foundation walls are covered with a high-density polyethylene waterproofing membrane, which redirects the water toward the drainage network beneath the floor slab. Usually, the pipes are connected to the sump pump, which is a basin that collects the water and discharges it outside away from the building. This method is highly effective and prevents the flooding of the basements.
The vapor barriers are another waterproof membrane effective for interior waterproofing basement
. The vapor barriers are waterproof and made up of plastic sheets. They are installed within the interior foundation wall. The membrane works by sealing off the moisture and preventing the dampness of the wall. Additionally, the membrane seals all the holes and cracks that might let the water into the basement.
Interior waterproofing is effective when the water is started entering the basements or is about to enter. Hence it becomes necessary to remove and redirect it towards the sump pump before it floods the basement. The water flooding inside the basement is due to the poor drainage system, the wetness of the ground surrounding the foundation wall, or damaged pipes. Therefore, waterproofing the basements is an effective method to prevent any future damage. Drainage system:
The cause of wet basements is commonly a problem with the drainage system. Due to the poor installation of a drainage system in the house, the water instead of going out travels back into the house or stands in one place. The water stands, and it starts to seep inside the basement walls. Various drainage systems are depending upon the location of your building and the soil surrounding your foundation. A sump pump or backwater valve is installed to remove the water surrounding the foundation or prevent the backflow of water. A sump pump averts water flow back into the system and prevents the water in the basement walls. The sump pump collects water and takes it away from the foundation. Backwater Valve Installation:
A backwater valve prevents standing water in one place during harsh weather conditions such as heavy rainfall or even worse flooding. Usually, during downpours water from the toilet or shower might seep into the basement via sewer lines. A backwater valve prevents the flooding of your basement during immense rainfalls, consequently avoiding the dampness or wetness of the basement walls and thus waterproofing the basement. Foundation crack injection:
Foundation crack injection is a method to seal the cement cracks when the cracks are due to the contraction and expansion of cement. The cracks are sealed by epoxy injection or polyurethane injection. Foundation crack injection serves the purpose of strengthening the wall and preventing condensation or moisture in the basement. Epoxy injection seals the cracks permanently, whereas, Polyurethane injection seals the spots of moisture and seepage. Call us at 416-400-2685
