Why Waterproof? Keep your building watertight & upright. By Val Williams f a building shows disturbing signs of water intrusion, its facility manager must take the necessary steps to mitigate the problem. Water damage can weaken the structural integrity of your building, threaten the health and safety of occupants, and expose the facility to the risk of building code violations. I Why Waterproof? Let’s remember that no other surface in a building takes more abuse than concrete floors and surfaces. These surfaces are subjected to just about every kind of abuse—impact, abrasions, water intrusion, chemical attacks and thermal shock. And, although we think of concrete as a solid material, it still needs waterproofing since concrete itself is not watertight. Plus, concrete surfaces tend to crack due to shrinkage, movement, and wear and tear. If it’s left unprotected, long-term corrosion of the reinforcing steel can occur. Waterproofing with the use of membranes and coatings acts as a barrier between the water and the surface and structure. It also protects buildings against elements such as chemicals, moisture, salt and other contaminants. Waterproofing products are specifically designed to be a lasting remedy for maintenance problems. They effectively protect against moisture and other corrosive elements, while prolonging the life of the concrete beneath it. Waterproofing Waterproofing should be done during regular building maintenance, when the facility conducts inspections, tune-ups and re-servicing. Otherwise, it can be applied during construction, retrofits and renovations. Facility and property managers can spot waterproofing problems through these visible signs: • Wet basement walls and floors are a sign of continuous moisture seepage coming from above or below ground. • Mold and fungi growth indicate a source of moisture. • Rot: Decaying wood or concrete is a sign that excessive moisture is changing the room temperature and humidity. • Pools of water: Water brought in by foul weather disappears in time. If pools of them remain, this means there is a failure in the building’s waterproofing system.
