Building with cinderblocks has become less and less popular over the past few years. Once the typical material used in basements, newer homes and buildings are increasingly built with poured concrete. However, if you have an older building, you likely have a basement constructed primarily with cinderblocks.
One of the biggest drawbacks to cinderblocks is their perceptibility to moisture and water seepage. Because they are so porous, water easily finds it way underneath the surface, sitting in the numerous air pockets to fester and eventually spawn mold, mildew, and other issues.
The best way to prevent this type of problem is by sealing your cinderblocks. Cinderblocks are extremely porous materials, featuring small holes and air bubbles of many different sizes. A silane/siloxane-based sealer is a far better option for sealing cinderblock its blend of large and small particles, designed specifically for porous material, penetrate the surface and chemically react below the substrate to form a water-repellent barrier. As the barrier is actually below the surface, it cannot crack, peel, fade away, or yellow over time, ensuring that your cinderblock looks beautiful regardless of actual age.
