MauerwerkImprägnierungen

MauerwerkImprägnierungen, also known as masonry waterproofing or impregnations, are chemical treatments applied to porous building materials like brick, stone, and concrete to reduce their water absorption. These treatments work by creating a hydrophobic barrier within the pores of the masonry. When water comes into contact with the treated surface, it beads up and rolls off rather than soaking in.

The primary purpose of MauerwerkImprägnierungen is to protect masonry from the damaging effects of moisture. Water penetration can lead to a variety of problems, including freeze-thaw damage, efflorescence (salt deposits), mold and algae growth, and structural degradation. By preventing water ingress, these impregnations help to extend the lifespan of the building material and maintain its aesthetic appearance.

Common active ingredients in MauerwerkImprägnierungen include silanes, siloxanes, and silicones. These are typically applied as liquids, either by spraying, brushing, or dipping. The product penetrates the pores and reacts to form a water-repellent film. It is important to note that most impregnations do not create a completely impermeable barrier; they reduce, but do not eliminate, water absorption. This allows the masonry to still "breathe," meaning it can release trapped moisture.

The effectiveness and longevity of MauerwerkImprägnierungen can vary depending on the product used, the type of masonry, and environmental conditions. Regular inspection and reapplication may be necessary over time. Proper preparation of the masonry surface is crucial for optimal performance.
