Investigative Foundation Monitoring

The sensors we use for concrete monitoring

Concrete Crack Monitoring

With concrete wall moisture investigations, leaks often show signs of water ingress from staining and concrete discolouration. When a leak occurs, you often want to know when it happened, how long has it remained at the location, is the moisture seasonal, does the moisture correlate with weather events (ie. condensation), or is the leak periodic?


By installing sensors, you easily gain information about the moisture to determine how you can solve the problem. The following sensors are what we would install:

Moisture Detection Tape (MDS)
  • Can be put along the crack or inserted into the crack

  • Cut to length

  • records when and how much moisture is detected when water bridges the stainless steel hardware.

  • Discrete and flexible

  • Can easily be put in different locations for a when/how wet measurement.

Point Moisture Monitoring Sensor (PMM)
  • Two screws that can be screwed into the concrete crack.

  • Used if you are looking for presence of water and when/how wet the concrete is.

  • Measures the resistance between the two screws

  • More localized moisture measurement versus the MDS Tape.

Embedded Moisture Sensor (EMS)
  • Installed by drilling and inserting into the concrete, (then filled with dry grout)

  • Gets the moisture level of the concrete surrounding it - not just water on the surface.

  • When two EMS sensors are installed at different depths in a slab, you will be able to see the different moisture levels in each.

  • Can show which way the water is travelling and which surface the water is drying to.

Concrete Moisture Sensor (CMS)
  • Once calibrated the sensor can give very accurate moisture level and moisture content readings in concrete.

  • Measures the capacitance and dielectric change of moisture in the concrete.

  • Can be “cut” in the slab, or poured in place.
