More often than not, concrete repairs are made before they become a more serious or costly issue, but there are measures that you can take to actually prevent future damage. This expansion causes distress on the concrete, which can lead to fractures that will continue to grow exponentially as saturation of the material increases.Ī wide range of restoration, repair and reinforcing services are offered by certified, specialty contractors who can repair cracks, spalls, rust spots, deterioration, pot-holes and heaves in concrete and masonry. When water infiltrates concrete, it can freeze, causing the water to occupy nine percent more volume than in its liquid state. In the winter, freeze and thaw cycles can cause big problems with concrete structures. Elastomeric breathable wall coating systems.The amount of sealant needed on a new or existing structure depends on exposure and expansion/contraction problems that may be identified. ![]() All wall penetrations provide easy access for water, bugs, field mice, birds or other unwanted pests to enter the building and cause damage.Ī structure's first line of defense against the elements is above-grade waterproofing, which includes the use of caulks and sealants to seal the perimeters of windows and other openings. There are also unplanned holes caused by aging brick joints that need re-pointing, vanishing sealants, damage from acid rain and settling cracks. It's easy to forget how many openings are required in commercial building walls-from plumbing and irrigation connections to lighting, HVAC system elements, exhaust vents, air intakes, joints around windows and doors, and fire alarms, to name a few. The exterior walls of a building can be a significant source of unwanted water leakage. Be sure to consult with an experienced specialty contractor when deciding which type of waterproofing to use. ![]() If there is a breach in any part of a structure's envelope, water is sure to find its way in.īelow is an outline of various types of waterproofing used for specific areas of a building or structure. ![]() Water is moved through a structure via any number of forces including hydrostatic pressure, capillary action, wind/air currents, surface tension and natural gravity. These small areas of a building’s envelope can cause the greatest damage and should be closely monitored and maintained consistently to protect the overall building. If the sealants, glazing or caulk joints at these transition points are failing or absent, water is sure to seep in and cause damage over time. Where the metal frame meets the surrounding wall.Where the glass of a window meets the metal frame.The one percent area of a building that causes most of the moisture problems is the gap where one component transitions into another. ![]()
