Cracks and water ingress: What can be done?

The only solution to eliminating any doubt about the significance of a crack is to use the water ingress testing technique. This simple technique requires the use of a garden hose to establish conditions conducive to water infiltration. Ideally, the crack should be visible from the inside of the basement or be directly accessible from the concrete floor, near the wall where the crack is located so that you can assess the problem.

The water ingress testing procedure

Here is the procedure for carrying out the water ingress test; it reproduces the initial conditions responsible for water infiltration:

  1. Use a garden hose with the water jet pointed directly at the visible crack of the foundation;
  2. Wait 30 minutes, the time required to confirm that the crack is indeed the cause of the water ingress;
  3. Note that in most cases the waiting time for water infiltration is 2 to 5 minutes;
  4. Pay attention to the result after 30 minutes of waiting time. If no sign of water infiltration is visible along the crack or on the floor, this indicates that the crack is not a problem, but does not necessarily mean that there is no problem. Further investigation is needed to find the real cause and ensure that it does not pose a risk to the building structure.

Although a visible crack is not always the sole reason for water infiltration, it remains one of the major causes. Consider performing a water ingress test as soon as possible to determine the severity of your cracks. The assessment of a crack will allow you to avoid subsequent degradation of your walls or your foundations and to proceed with repairing and sealing the foundation cracks.
