Our Approach to Basement Waterproofing and Foundation Repairs

At Oosterveld, we believe in clear communication, expert workmanship, and transparency at every stage. Here’s what you can expect when working with us:

1

Evaluation & Assessment: We perform a complete inspection of your basement to detect signs of water intrusion or foundation instability.

3

Interior Waterproofing Systems: We install weeping tiles, moisture barriers, and other advanced drainage solutions tailored to your home.

Foundation Crack Repair: We seal any cracks using durable epoxy or polyurethane to prevent future leaks and reinforce the structure.

4

Structural Reinforcement: Where necessary, we reinforce weakened foundation sections to restore long-term strength and stability.

Reliable Waterproofing and Foundation Solutions for a Safer Home

Without proper waterproofing, moisture from surrounding soil can enter your basement through porous concrete or cracks—especially during seasonal shifts in Guelph’s weather. As water freezes and expands, small issues can quickly become serious damage.

Oosterveld Heating and Air Conditioning delivers interior waterproofing solutions that stop the problem at its source and keep your home protected.

Crack Repair for Foundations

We identify foundation cracks and seal them using high-strength materials designed to stop water penetration and strengthen the surrounding structure. These repairs help restore your foundation’s integrity while preventing further water-related damage.

Interior Drainage Systems

Even without visible cracks, water can still enter your basement through pressure points like pipe penetrations, window wells, or the concrete slab itself. We install interior drainage systems that redirect water away from your basement and prevent pooling on the floor.

Sealants and Coatings for Waterproofing

We apply waterproof membranes and vapor barriers to basement walls to block moisture and reduce the risk of leaks and mould. These protective layers keep your space dry and your home safe.
