Our Basement Waterproofing & Foundation Repair Process
We believe in transparency throughout the entire process. Here’s what you can expect when we waterproof your basement:
1
Inspection & Diagnosis: We inspect for foundation cracks and other areas where water is getting in.
3
Interior Waterproofing: When needed, we install drainage systems, waterproof membranes, and weeping tiles.
2
Foundation Crack Repair: We apply sealing methods to close gaps and stop further damage.
4
Structural Reinforcement: If foundation stability is an issue, we’ll reinforce it to restore long-term safety.
Waterproofing & Foundation Repair to Protect Your Home
Without effective waterproofing, the soil around your home can push moisture into your foundation. As the seasons change in Canada, water in those cracks can freeze and expand, worsening the damage and creating more leaks.
Boonstra uses proven interior waterproofing techniques to keep basements in Hamilton dry and protected from the ground up. Our services include:
Foundation Crack Repair
Hairline cracks can lead to larger structural concerns if left alone. We begin your waterproofing service by identifying all the visible and hidden cracks. These are sealed using polyurethane or epoxy injection to block out moisture and prevent further penetration.
Interior Drainage Systems
Water doesn’t always need cracks to enter your basement. It can come through pipe openings, window wells, or even the concrete itself under high hydrostatic pressure. If water is pooling along your basement floor, we can install a complete interior drainage system to collect and redirect it safely away.
Waterproofing Coatings & Sealants
To boost your basement’s moisture protection, we offer waterproof coatings and vapour barriers that are applied directly to your walls. These barriers help reduce moisture buildup, discourage mould, and offer long-term durability.
Prevent water damage before it leads to bigger problems. Call Boonstra now for professional basement waterproofing and foundation repair in Hamilton.
