When exterior foundation waterproofing fails—or is simply too costly to repair—SUPERSEAL’s Interior Basement Waterproofing System offers a smart, affordable solution to keep your home dry and protected from the inside.

In many homes across North America, foundation walls are aging, cracking, or were never properly sealed from the outside. Excavating to fix exterior issues can cost thousands. That’s where SUPERSEAL comes in.

Our Dimpled Membrane System is designed to permanently divert water and moisture to your sump pump, controlling interior seepage and keeping your basement dry—without expensive digging or disruption.

Why Choose SUPERSEAL Interior Waterproofing?

✅ Cost-effective alternative to exterior excavation
✅ Diverts water away from walls and insulation, reducing risk of mold
✅ Protects your insulation—just 7% moisture can reduce its thermal efficiency by up to 70%
✅ Improves indoor air quality by reducing dampness and musty odors
✅ Ideal for finished or unfinished basements

Whether you're finishing a basement, dealing with seepage, or simply want a drier, healthier home, SUPERSEAL Interior Waterproofing is your trusted solution.

Engineered for Long-Term Protection

Installed on the inside of your foundation walls, our dimpled membrane creates an air gap that channels moisture directly to your sump system. This process not only protects your home’s structure but also ensures your insulation and interior walls remain dry and efficient.
