Basement Wall Vapor Barrier

Water in your basement not only compromises the structural integrity of your property but can cause mold growth, putting your family’s health at risk.

The AquaStop™ WallSeal™ Basement Wall Vapor Barrier, provided exclusively by The Basement Guys, safeguards your basement against water damage and ensures the safety of your home. Using this product alongside our other basement waterproofing solutions provides peace of mind by removing unwanted moisture from your downstairs space.

WallSeal™ is an essential piece of kit for homeowners across Ohio. But how does it work? And when would you need it? Learn more below.

What Is WallSeal™ Vapor Barrier?

Essentially, WallSeal™ is a 12-mil thick barrier that fights against moisture intrusion in your basement. It attaches to a basement wall and drives water leakage to our exclusive AquaStop™ BasementGutter™ interior drainage system, instantly removing moisture and dampness.

Using a vapor barrier like WallSeal™ with an interior drainage system, sump pump, and dehumidifier protects your property against water damage.

Signs You Need a Basement Wall Vapor Barrier 

A wall vapor barrier like WallSeal™ can help if you notice any of these problems in your basement:

  • Distinct musty smell 
  • Mold growth 
  • Efflorescence on concrete walls or floors
  • Damp walls
  • Cracks in walls
  • Elevated humidity levels
  • Leaks and water accumulation
  • Leakage around windows

Ignoring the signs of water in your basement could affect your property’s structure and your family’s health. So contact a professional like The Basement Guys to solve the problem.

Is a Basement Wall Vapor Barrier Necessary?

Even if your basement walls seem dry, they can easily succumb to moisture. Using a wall vapor barrier as soon as you notice water issues can prevent further problems.

We strongly recommend our WallSeal™ Basement Wall Vapor Barrier to maintain a dry and safe home.

How Our WallSeal™ Vapor Barrier Works

Our certified technicians use tried-and-tested methods to ensure the longevity and effectiveness of the WallSeal™ system. After a detailed inspection, we’ll install our vapor barrier in a few simple steps:

  • Cleaning and preparing basement walls. 
  • Adhering durable WallSeal™ sheets to fit the length and width of your basement walls.
  • Installing an interior drainage system and remaining components.
  • Determining the basement’s lowest point and installing a sump pump system.
  • Connecting interior drains to the sump pump.
  • Adding an energy-efficient basement dehumidifier.

Here’s how a fully integrated WallSeal™ system keeps your basement safe and dry:

  • If moisture seeps in through cracks, it runs behind the WallSeal™ barrier.
