Water infiltration: Perform the water ingress test

Uncovering the nature of a water infiltration and determining solutions to the problem can seem complicated when we do not know where it came from.  To this end, you can use a water ingress testing technique to determine the severity of cracks in your facade or foundation.

Cracks and water infiltration: what to think?

Water infiltrates in many ways. It works its way through the smallest flaw at the first available opportunity. Water ingress in foundations can cause many problems for your home.

What causes water infiltration?

  • Evidently, one of the main reasons is the formation of a crack in the walls or on the foundation floor.
  • Concrete damaged or contaminated by pyrite.
  • Clogged gutters.
  • A backflow from public sewers or septic systems.
  • Non-existent, insufficient or defective waterproofing of foundations

A visible crack

You just discovered a crack on your house foundation and you have some doubts about it. The only thing that comes to your mind is: “Is this crack really an issue? ”

  • Nothing dramatic, it is too small;
  • The crack is only on one side of the concrete wall;
  • It does not go down to the base of the foundation wall.

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.
