One of the recurring problems in basement floors is that of moisture seepage. However, moisture is always not easily detectable. Often, it is observed only when extensive damage has already been done to the flooring and wall surfaces. One of the easiest ways of avoiding this problem is testing the basement floor for moisture.
Tools and Materials
- Duct tape
- 2x2-inch piece of aluminum foil
Step 1 - Cut Foil
Use a pair of scissors to cut a piece of aluminum foil, measuring 2x2 inches.
Step 2 - Position Foil
Locate a spot on the basement floor that you suspect of containing moisture. Using the duct tape, stick the piece of foil upon the chosen spot. However, don’t tape every side of the aluminum foil. Leave one of the 4 edges slightly open to allow some air to seep inside the foil.
Step 3 - Inspect Foil
After 24 hours, pull away the foil to inspect it. Assess the side of foil that was against the basement surface. If there is any moisture on this side of the foil, there is some moisture within the basement floor. This indicates problem of improper ventilation or drying of the basement floors or water seepage from a surrounding source. This suggests that you might need better water-proofing for the basement.
If the moisture is present on the outer side of the foil, the problem lies in condensation of moisture within the basement area. Here, the solution lies in using a dehumidifier.
