Concrete Moisture Remediation Services

It is natural for moisture to seep up through concrete slabs. This is known as Moisture Vapor Transmission, or MVT. Typically, this can be a result of several conditions, such as water trapped in an absorber in the slab, concrete drying, or concrete coming into contact with soil. Moisture or vapor is drawn out from the bottom of the slab by capillary action and up to the surface where it condenses. While it is natural, the water that collects on the surface of the flooring can have devastating effects, and is often the reason why flooring system failures occur.

To prevent the failure of flooring systems, simple techniques for moisture control can be applied, and doing away with the damaging aspects of concrete can help as well. For instance, there is high pH liquid build-up under coatings which weakens epoxies. Quality epoxy coatings will last longer, so these are more practical over the long haul. Some additives can also play a role in the occurrence of MVT, and determine whether a slab is safe to coat or not. A concrete slab’s porous nature and wet weather conditions can be a dangerous combination, so this must be considered and dealt with when applying the concrete mixes for flooring.

Core testing was designed for use in the identification of flooring systems that are best suited for different facilities. Lower concentrations of salt and calcium chloride are needed for safe coating. The typical water to cement mixture ratio is also best since this prolongs the life of the concrete, decreases capillary action, and averts MVT problems. MVT can be a very serious concrete flooring problem if not dealt with immediately. One reason is because the seepage is not noticeable, and so the floor deteriorates before the problem becomes apparent. With core testing early on, it becomes easier to pinpoint the levels of additive content needed for different preventive measures and/or contingencies. Measures of relative humidity and MVT are the most important numbers to look at when assessing the concrete flooring to determine whether it is in danger. If the relative humidity is found to be above acceptable levels, an MVT test is recommended. If the weight goes over the recommended, RH testing is needed. These simple precautionary procedures will secure your investment because having the right kind of flooring system for the existing conditions in your facility will help you avoid untimely costly repairs.
