Foundations are designed to keep out moisture, provide insulation, and give a stronghold of the structure. They should stay in tact to keep a home healthy and resilient. When surveying your foundation, look for cracks that appear potentially harmful. They could allow water, gas, and humidity inside which leads to expensive repairs and damages.
The most common remedy of fixing these gaps is by injecting a sealant into the whole fissure. A contractor will simply attach injection ports along the crack then apply a surface sealer. Once it hardens, the contractor will then inject the main sealer through each port. These sealers can reach all the way through the crack to the outside, preventing anything from getting in.
Types of Sealants
- Epoxy – This sealer is great for multiple horizontal or wide cracks that could interfere with the structure. Epoxy bonds well with concrete and has been used for many years to properly waterproof foundations. However, any shifting of the home could cause the rigid sealant to crack itself.
- Urethane – For leaky, wet cracks, urethane is ideal because it expands with water to fully fill the gap. This sealant is also flexible so structural shifting won’t matter since it moves with the concrete. Urethane is now the more popular material because of its plasticity.
If a foundation is at risk for damage because of cracks, filling them should be essential. This easy injection repair process will ensure that the structure remains in-tact and long-lasting.
