Exterior Basement Waterproofing
MOISTURE IS THE ENEMY OF BASEMENTS
|Waterproofing the exterior foundation walls will give you a structurally sound foundation and eliminates the amount of deterioration that will occur to your foundation walls. This can save your home thousands of dollars in repairs. Sometimes belongings can be ruined by leaky basements where too much moisture buildup damages property and leads to mold infestation.
Basement moisture or water problems can reduce the value of your home, most realtors will advise their customers to fix their basement before offering their homes for sale. By doing so, your property value will increase immediately once it has been sealed and waterproofed.
Waterproofing your basement from the exterior is highly recommended because the water problem is addressed from the source. Waterproofing your home from the exterior allows you to restore the foundation to its natural state as well as allowing you to gain maximum drainage around your property by installing new weeping tile.
Exterior waterproofing is a system that requires excavation around the perimeter of the building. The excavation depends upon the depth of your basement; most excavations typically range from 4 to 8 feet deep and approx 2 1/2 feet wide. Excavation to the footings where the old weeping tiles are, is necessary; the tiles are removed and new 4 inch weeping tile with gravel is installed. Foundation walls are then cleaned and inspected for any voids or structural cracks which are then filled.
We then apply a rubber membrane which will be the main ingredient to waterproofing your foundation; this product elongates, which allows the product to expand if any further settlement occurs in your foundation. Then we apply a dimpled sheet of drainage membrane which is fastened to the wall, this membrane will act as a protection board and a drainage membrane.
Once the waterproofing and membrane has been installed a layer of 3/4″ clean gravel is placed over the weeping tile to maximize the drainage to its fullest potential. Then the area is backfilled with its native soil. Once this system is completed your foundation is waterproofed and will have no further issues with water penetrating from walls into your basement.
