Frozen French Drain
CAUSES OF FROZEN EXTERIOR DRAINS
With the onset of winter and temperatures dropping below freezing, pipes and water mains can freeze.
In the Greater Montreal area, due to the clayey nature of its soils, the movement of the soil, accentuated by freeze/thaw periods, can increase the risk of movement of your foundation and its installation (especially the French drain).
An important part of the drainage system, the exterior drain can freeze if
- The drain is not buried deep enough
- The slope of the drain is not well respected, causing water retention
- The drain passes through a cellar downspout or a driveway
HOW DO YOU KNOW IF YOUR FRENCH DRAIN IS FROZEN?
To make sure that your French drain is not frozen, you can do a test to run water in the access stacks.
If you still have doubts, you can call a Lesage Excavation specialist. He will come and inspect your installation to detect a possible problem (either with an infrared thermometer or a camera).
DEFROST AN EXTERIOR DRAIN
If your French drain is frozen, we will have to excavate it in order to gain access. Once the excavation is complete, we use a high-pressure jet of hot water to thaw it out. Once the drain is thawed, we can inspect it with a camera to determine the cause of the freezing. In order to get through the winter period without worrying if the cause cannot be remedied immediately, we can install a heating wire in the drain to maintain a constant water circulation in the drain.
REMEMBER TO CHECK YOUR INSTALLATION DURING A THAW
During a winter thaw or heavy rain, the French drain should be draining water into the catch basin and the submersible pump should be working. If no water is entering the pond and there is no sign of activity, the drainage system should be inspected immediately.
