Moisture In Concrete Slabs Problems

These problems are not only disrupting functions of the building due to maintenance operations but also costly.

Moisture in concrete slabs problems.

Many adhesives used for installation of floor coverings are more water sensitive than in the past due to restrictions on the use of volatile organic. Having a breathable carpet originally you may not have noticed anything. This could potentially be problem related to moisture in the concrete. High shrinkage leading to excessive random cracking and curling and uncontrolled vapor transmission.

Concrete moisture and flooring materials. Concrete slab moisture can cause problems with the adhesion of floor covering material such as tile sheet flooring or carpet and bond related failures of non breathable floor coatings. How to do a moisture test for concrete slabs. If there is too much moisture in the concrete and an impermeable layer is placed over it the moisture migration can delaminate the coating sealer or overlay.

Concrete moisture is more problematic in below grade basement locations where conditions are naturally humid but it can also be a problem for on grade slabs as well especially when they are new. Older slabs of this type probably don t have an intact vapor retarder below the slab so moisture is able it get into the slab from the soil below. Duct tape an 18 inch square piece of plastic onto the exposed concrete and leave it for 16 hours. We have it within our power to produce and place concrete in a way that will help solve the two most egregious problems associated with slabs on ground.

Thanks for the question. Added to that beneath continuous flooring moisture can also cause floor darkening or discoloration efflorescence deposits and other. Commonly concrete floors are vulnerable to moisture and suffer from different detrimental influence of moisture such as lifting tile off the floor rotting hardwood damping carpet coating delamination and many more. For instance lifting tile off the floor rotting hardwood damping carpet and coatings delamination.

Concrete slabs on grade and basement slabs are weak and vulnerable to the detrimental effect of moisture which may lead to various problems. But the biggest problem for decorative concrete with a lot of moisture moving through a slab is the pressure it exerts at the surface. One of the simplest most economical test methods for determining whether there may be moisture in concrete is the astm d 4263 concrete moisture test. A concrete slab on ground is the heart of an industrial facility.

Moisture problems with concrete slabs by peter craig moisture related floor covering and coating problems have in recent years become among the most common and costly issues being faced by design professionals contractors manufacturers installers and building owners. The means are at hand to thwart operational disruption in these buildings.
