Waterproofing Your Basement Foundation


Any homeowner who has been greeted by a musty odor and damp walls at the bottom of the basement stairs knows that keeping water out of the basement is no easy task. While it may sound like a major project, waterproofing your basement can save a significant amount in the long-term. Always contact a plumber to get the job done right.

Water In the Basement Foundation
One of the main causes for leaks in the basement is an issue with groundwater seeping into the basement foundation. This is fairly simple to diagnose, but a plumber could also be a helpful source of information when it comes to basement leaks. First, check outside around the perimeter of the house and notice the slope of the ground. If the land is sloping down from the house, rain water is able to drain safely away from the foundation. However, if the ground slopes back toward the home’s foundation, you will probably see some drainage issues as water flows down into the foundation, ending up in the basement.

How to Waterproof the Basement Foundation
It is recommended you contact a professional like plumber Toronto rather than tackle this yourself. The first step of waterproofing the basement is to keep water from getting there in the first place. If you notice that the ground around the foundation is sloping down toward the house, add enough dirt around the perimeter of the house to create a 2-inch drop for every foot away from the house. Also ensure that downspouts from the roof are letting water out at least five feet away from the foundation.

Next, waterproof the walls inside the basement by applying a waterproofing solution – there are several brands of solutions and sealants available. These products work by plugging cracks or holes that water may seep through and creating an airtight seal and work best when applied to unpainted brick or concrete. Be aware that you may need to repair larger cracks in concrete or holes where pipes or tie rods come through the wall before applying a sealant.

More Serious Basement Leakage
Depending on the situation, some homeowners may also consider installing a sump pump in the basement floor. A plumber service can let you know if this is feasible for your home. The sump is located under the floor, and pumps water outside the house when the water level becomes too high. Serious water issues could also benefit from a perimeter drain under the floor. This requires digging a trench around the perimeter, laying piping, covering with coarse gravel, and refilling around the pipe with concrete.

Waterproofing your basement is an effective way to increase the value of your home and prevent future water damage to your property due to leaks and moisture.
