Interior Basement Drainage Systems

The Perma Dry Waterproofing foundation drainage system is designed to lower the water level under the slab, helping to prevent water from rising from the edges or through floor cracks in the basement slab.

Exterior Basement Drainage

At Perma-Dry, we look both outdoors and indoors so we can properly assess and determine with clarity the conditions creating the water intrusion source.

Basement Wall Moisture Barrier

Our rigid Wall Guard system acts as a moisture barrier between the basement foundation wall and finished items in your basement (framing, insulation, sheet rock).

Drain Pipe Cleaning

Based on the age of the home or building the type of piping utilized when it was built may have simply exceeded its shelf life.

Basement Ventilation

Ventilation in your basement gets rid of the excess moisture and humidity that causes mold, dampness, musty odors.

We had had our basement flood twice in a couple of years. Perma Dry found a poorly sealed crack in a foundation wall and repaired it beautifully. Even with huge rainstorms, we haven't had a drop of water. Highly recommended.

We've had several very wet storm seasons since the installation three years ago, and the basement has remained bone dry, even while water covers large parts of our yard. We've doubled the usable space in our house.

These folks were EXCELLENT. I mean "first class". Perma Dry delivered on their promises. I've had perfect and wonderful dryness. Nope, they didn't pay me to write this. I'm just a genuinely satisfied customer.
