The process of exterior basement waterproofing in Hamilton is a crucial aspect of building maintenance as it helps to maintain the structural integrity of a building. By excavating around the foundation, any cracks or defects in the foundation walls can be identified and repaired. Once the repairs are complete, a waterproof membrane or coating is applied to the outer side of the foundation walls to prevent water from penetrating the basement. This process not only protects the basement from water damage but also ensures that the building remains structurally sound and avoids the need for costly repairs in the future.
