Waterproofing a basement is important if a building is constructed at or below ground level. If construction is taking place where the water table is especially high, masonry is at great risk of cracking damage due to the tremendous amount of pressure. A combination of adequate draining and waterproofing strategies will help prevent many foundation problems. New homes can benefit greatly from exterior waterproofing.
Homes built before 1980 received only a degradable covering to help prevent dampness. This method provided only temporary protection and much better techniques and products exist today to safeguard a house from the outside in. Polymer products can completely protect an exterior wall, effectively preventing water from entering a basement. Unlike the earlier products, the polymers are not affected by different levels of pH in the soil, and will last for the lifetime of the structure.
Solid waterproofing in the first place will help prevent costly repairs later. Water leakage in the basement can ruin insulation, drywall, framework, and any other expensive finishing. Sometimes, however, there are factors that can combine to create cracks despite preventive measures. In that case, it is imperative that the building owner pinpoint exactly what has caused the problem and then take immediate action to repair the problem before disaster occurs.
Many conditions can lead to cracks in foundations, basement floors, or a masonry foundation wall. Some cracks result from leakage or the initial settling of a home; sloppy construction can be to blame or the foundation may be subject to undue pressure. Before any attempt is made at waterproofing a crack for repair purposes, it is probably best to consult a professional. A professional can diagnose the cause of the crack and offer the best solutions so that the problem will not recur.
It is essential to keep water from creeping into the basement through the crack and do further damage; waterproofing will repair the fissure quickly and efficiently. One way to waterproof is to use polyurethane foam injections. The foam is injected into the crack in liquid form, allowing the material to fill in the space completely. The liquid interacts with the existing water in the crack, creating foam with up to 30 times the volume of the original liquid that was inserted. Once set, this foam is able to withstand enormous amounts of pressure and bonds securely to the concrete.
The importance of prevention of or timely repair of basement or foundation wall crack repair cannot be overstated. Waterproofing either before or after damage happens saves money and heartache.
