If you ever wondered why your concrete surfaces crack, sink and wear out, moisture is the most common culprit, damaging the slabs and creating the need for costly repairs. Not only does moisture cause problems, but it also slows down other construction works such as installing additional floor coating. Here are some basic facts about moisture!
Why are moisture problems so common?
Most construction-related problems are caused by rushing the natural processes, such as drying and settling of concrete, by busy construction companies. Tight schedules often do not allow sufficient time for the concrete to dry before installing the flooring or applying coating materials.
Another common problem is the lack of necessary moisture-protective materials that should be installed below the slabs. The materials used instead often do not provide the required protection, are not installed in the right manner or can be damaged during the construction.
How does the moisture reach these areas?
There are several types of moisture that cause damage to concrete flooring. One of them is “the water of convenience” or free water that is actually within the material itself, used to hydrate the cement particles and form the concrete mixture used in construction. This water does not become a part of concrete but instead stays present within the pores and capillaries of the material.
Another sort of moisture causing damage is the one rising from below, underneath the concrete slabs. To avoid continuous contact of concrete with this kind of moisture, usually, a low-permeance and vapor retarder materials are installed first. The lack of this protection makes the flooring susceptible to damage from moisture, no matter the depth of the underground water source.
What if there is not enough time for a natural process of drying?
Accelerated slab-drying techniques can be used if necessary in specific situations, but only if effective moisture protection is installed beneath the concrete to help control the moisture.
