Concrete Moisture Testing

Moisture-Detection-and-Humidity-ReadingsMoisture infiltration is often associated with wood or drywall but it can also occur in concrete surfaces. As a result, whenever humidity testing is done in a Toronto home, the concrete needs to be checked for moisture as well. This is essential when looking for hidden damp pockets and to ensure the proper removal of moisture. Concrete moisture testing is also used to determine when an area can be considered properly dried in accordance with industry standards. It is only after concrete moisture testing shows proper results that the emergency drying phase of remediation can end and the repair and renovation stage can begin.

What Causes Dampness in a Home?

“Damp”, when used in a structural context, basically means the presence of any moisture that isn’t supposed to be there. Dampness usually comes from either condensation or infiltration and can arise from both external and internal sources.

External Sources of DampnessMoisture-Map---Where-Water-Comes-From

  • From Above: Rain or melting snow and ice can leak through the roof of your home.
  • From the Sides: Wind-driven rain or snow can buffet and infiltrate the walls of your home and air movement in general is capable of bringing in moisture, particularly during rainy seasons.
  • From Below: Flooding can arise from rainwater flowing towards your foundation or if storm drains become obstructed and unable to remove water faster than it arrives.
  • From Extra-Below: Water molecules like to stick together and water likes to stick to other things. These factors combine to cause “capillary action” that allows water to climb up narrow tubes in what seems like a defiance of gravity. Capillary action can allow ground water to infiltrate any crawlspaces underneath your main basement.

Internal Sources of Dampness

  • High indoor relative humidity and limited mechanical ventilation can allow for vapor diffusion, the transport of moisture droplets through the walls.
  • Condensation from showers, baths, cooking, and other sources of evaporation can cling to and infiltrate walls if not cleaned up properly.
  • Any other spill or pipe leak.

How Is Concrete Moisture Testing Performed?

Without getting too technical, we stick a probe in the floor or wall to get a reading of how much moisture is passing through that section of concrete. It usually takes a series of readings, each in a different location, to get an estimate of how much moisture is within the floor or wall of an entire room. These readings are then compared to the relative humidity of the air to see if anything is out of the ordinary. Generally speaking, the moisture level in the concrete should not be higher than that in the air and localized damp patches are particularly concerning.

If there is still high levels of moisture in the concrete, structural drying equipment such as air movers and/or dehumidifiers will be installed or (if already in use) repositioned to ensure they have a better effect on the concrete.
