Types of Foundation Waterproofing Services We Offer
We offer a range of waterproofing services to protect your home’s foundation from water infiltration and damage. Whether you’re looking for exterior solutions, basement protection, or crawl space sealing, GAMCON has tailored services for you. Here’s a closer look at what we do:
Exterior Foundation Waterproofing Solutions
Exterior foundation waterproofing is one of the most effective methods for keeping water out of your foundation. By addressing the problem at its source, we ensure moisture doesn’t even get a chance to enter your home. Our process involves excavating around the foundation, applying a durable waterproof membrane and setting up drainage systems to direct water away from your property. This approach prevents water damage and extends the life of your foundation.
Interior Foundation Waterproofing for Basements
If water has already managed to get into your basement, our interior waterproofing solutions can help. We install drainage systems like French drains or sump pumps to capture and redirect water before it can cause damage. We also add vapour barriers to reduce moisture buildup. This method is especially effective for finished basements or homes where an exterior excavation is not possible or feasible.
Crawl Space Waterproofing and Sealing
Crawl spaces are among the most overlooked parts of your home despite being particularly prone to moisture problems that can lead to mould growth, structural damage, and even poor indoor air quality. At GAMCON, we offer crawl space waterproofing that includes encapsulating and sealing to protect these areas. It safeguards your home from water damage and improves its energy efficiency.
