Exterior excavation and membrane waterproofing is the most effective way to stop water infiltration at its source for Michigan basements. This proven method involves excavating the soil around your home’s foundation and applying a seamless, flexible polyurethane membrane to the exterior wall. Unlike traditional sheet materials, polyurethane membranes cure into a continuous barrier that eliminates leaks at seams, providing superior protection against water intrusion and foundation damage.
This exterior waterproofing solution is ideal for homes experiencing seepage above the foundation wall, porous masonry walls, or finished basements where interior demolition is undesirable. The process includes trench excavation, thorough cleaning and repair of the foundation wall, professional membrane application, installation of drainage boards, and careful backfilling. By stopping water before it reaches your basement, this method safeguards both your foundation and valuable living spaces.
Although exterior excavation is more invasive than interior waterproofing systems, it offers a long-term solution for persistent basement leaks, especially in homes with stone or brick foundations. Experienced Michigan waterproofing contractors ensure safety by marking utilities, using proper shoring, and grading the soil away from the house. For lasting basement protection and peace of mind, exterior membrane waterproofing is the trusted choice for Michigan homeowners seeking reliable, permanent results.
