Weeping tiles are pipes with drainage holes located underground around the basement foundation. Usually they are located on the exterior next to the footing. In homes that have had an Internal Breakout retrofit, the tiles are next to the footing on the inside of the basement. When it rains, water filters into the ground. These pipes capture the water and take it away from the foundation walls to prevent groundwater from entering the basement. Weeping tile systems are sometimes called foundation drains, perimeter drains or simply drain tiles.
Over time, weeping tiles can become clogged with soil, tree roots and other debris. Blocked tiles are a leading cause of wet basements. This water has to go somewhere and will always take the path of least resistance. Often a homeowner will think that the water in the basement is due to a crack in the foundation wall or floor when it is actually the result of a drain blockage.
Most houses built prior to 1970 have a drain system consisting of short sections of clay tiles.
These tiles have a tendency to shift, especially when surrounded by heavy clay or other types of soil with poor drainage. Our annual freeze and thaw cycles will aggravate the problem further.
After a thorough inspection of your home and surrounding lot, your DryBasements.com Estimator will recommend the best course of action based on the age of your house, previous tile problems if applicable, and the location of outside structures and landscaping. In some cases, a test dig outside the home will be recommended in order to ascertain the type and condition of the tile. A video inspection may be required to check the condition and location of the tile runs.
This service should always be considered a temporary remediation. The condition that led to this problem still exists and eventually the weepers will become plugged again.
Scoping, also known as a video inspection, may allow us to see an obstruction, collapsed or damaged areas, the intrusion of roots, or at times to map the location of connections to or from the weeping tiles.
In some homes built prior to 1985, the weeping tile was hooked up to the sanitary drain. This leads to a hazardous situation if the sanitary sewer ever backs up from the street—not to mention the experience of having your basement and possessions destroyed by raw sewage.
Fortunately, many cities, including London and Stratford, have a special subsidy program to help affected homeowners disconnect their drainage system from the municipal drain and to install a backflow valve to prevent sewage from entering the basement. Your DryBasements.com Estimator will give you full details on our Basement Isolation Program.
Window well drains are an important component of any weeping tile drainage system. If these drains become plugged, or if you have an older home without drains, rain water and moisture from the soil can seep into your home through the basement wall or window frame. Left unchecked, this can lead to loss of structural integrity as well as mould and mildew buildup. Make sure your window well drains are working properly. Contact DryBasements.com.
