How Moisture Damages Concrete Floors

When Small Cracks Lead to Big ProblemsMany homeowners know hardwood floors and water (or more accurately, moisture) do not mix. Liquid and moisture can weaken the wood surface, causing it to stain, warp, and, with the right pressure, break.

This phenomenon, however, is not exclusive to wooden floors, as concrete floors are also vulnerable to excess water and moisture. Whether it is during construction of the floor or maintenance, too much moisture here and there can put your concrete slabs at risk.

When Small Cracks Lead to Big Problems

Concrete contains moisture—you cannot mix cement with gravel without water. When water seeps into the tiny cracks and holes in the floor, it stays there until it can find a way out, usually through evaporation.

As the moisture evaporates, it will push through any barrier on top of it until it can rise freely into the air. Outdoors, this evaporation often results in potholes. This is evident indoors, meanwhile, through the presence of large cracks on the floor and other surfaces.

Concrete floor solutions provider VisionInstallations.co.nz explains this is where waterproofing and moisture barriers become of great help. More than protection from stains and spills, waterproofing your floor minimises the moisture that seeps deep into the concrete, which then minimises possible damages from extreme heat and vapours.

When Hot is Not… Acceptable

Water vapour from the floor and other surfaces of your home can make rooms more humid, which could pose a problem for new tighter home construction. It can make the indoors uncomfortable and may even promote mould growth.

When Moisture Becomes a Beauty Problem

Certain concrete floor slabs are also more vulnerable to staining. Slabs with high moisture movement can easily blacken or discolour, especially if the stain has copper salts. Moreover, too much moisture can exert enough pressure on the concrete surface to delaminate coatings or overlays.

Too much of anything can be bad, and when it comes to moisture, it can definitely wreak havoc on homes and buildings. It’s always best to protect your floor any way you to make it last longer.
