Basement Waterproofing Repair

interior footing drains

The SuperDry sub-floor drainage pipe and stone are next to the foundation footing.

We engineered the SuperDry waterproofing system to eliminate water at the source.

Our system uses perforated, corrugated drainage pipe placed at the proper depth and angled with a carefully calculated downward pitch toward the sump pump station.

During heavy rainstorms, water moves quickly through the pipe, eliminating groundwater and lowering the hydrostatic pressure around your house.

The pipe is perpetually self-cleaning and never clogs with mud giving you one less thing to worry about.

The SuperDry System

interior basement drainage and sump pump

The SuperDry system is designed to remove a high volume of water beneath your basement slab floor.

American Dry Basement Systems installs the best waterproofing systems using advanced, customized, effective engineering solutions. After 25+ years, our systems still have the lowest service requests in the industry. It's that good.

We don't use cookie-cutter, rigid, on-the-footing drain channels for a good reason.

The only way to remove groundwater before it turns your basement into a damp sauna is 12 to 14 inches beneath your floor. That way, water will never perk up or rise and touch the bottom side of your floor.

The rigid, on-the-footing drain channels only start working when water is already touching the underside of your floor and sitting in water. It's too little, too late.

Our approach is genuinely powerful, effective, and configurable to any foundation, whether poured concrete, cement/cinder block, or stone wall foundation.

Our interior waterproofing system protects your basement using two distinct parts:

A maintenance-free, self-cleaning drainage system capable of moving water to your sump pump station without touching your walls or floor.

A dependable sump pump station that removes water fast enough to keep you dry during the rainiest seasons. Also, during the winter season, our optional Freeze-Free vent will stop the discharge line from freezing, allowing water to continue flowing out of the house during the coldest winter months.

Our American Dry Basement Systems installers installed over 50,000 sump pumps and battery backup systems. We know a winning combination that will end your water problems.

Key features of our sub-floor drainage installation:

Structural Integrity

We create engineering tabs around your floor to maintain the outward pressure to support walls.


Original floors are 3.5 to 6 inches thick & building code compliant. We replace what we take away, which improves resale value.

Concrete Repair

Our proprietary SuperCrete for floors & SuperSlurry for walls has a crystalline component that grows into concrete, strengthening and waterproofing it.


Our drainage pipes are perpetually self-cleaning & never clog. Other systems have costly annual maintenance requirements.

Lifetime Warranty

We guarantee that you will never require an annual flush maintenance program, get mud-clogged drainage or cracks in your treated floor or walls, or we will fix them for free.
