Basement Wall Vapor Barrier

Ohio Basement Authority and The Basement Guys have now merged.

Basement wall vapor barriers, coupled with other basement waterproofing solutions, keep moisture where it belongs—out of your basement. As a leader in moisture management, Ohio Basement Authority installs the AquaStop WallSeal™ Basement Wall Vapor Barrier as an effective way to protect your home from water damage. 

By reading this page, you’ll gain valuable insights into solving your basement moisture issues for good. 

What is the WallSeal™ Vapor Barrier? 

The WallSeal™ Vapor Barrier is a 12-mil thick, high-quality barrier designed to prevent moisture intrusion in your basement walls. 

It is permanently fastened to the wall, directing any wall leakage down into our BasementGutter™ interior drainage system. This method offers immediate relief from wet walls. It is a finish-ready vapor barrier, making it part of a more extensive whole-home solution for optimal living conditions. 

Combining our vapor barrier with other basement waterproofing solutions—including a sump pump and dehumidifier—creates a comprehensive system that protects your property and enhances your home’s value. 

Signs You Need a Basement Wall Vapor Barrier 

Your home could benefit from a vapor barrier, especially if you notice these common basement problems: 

Ignoring these warning signs or delaying their repair could lead to structural damage and health risks, making timely intervention crucial. Contact a local basement waterproofing professional like Ohio Basement Authority when you notice any of these problems in your basement. 

Is a Basement Wall Vapor Barrier Necessary? 

Yes, a basement wall vapor barrier is essential to a comprehensive basement waterproofing solution. 

Even if basement walls don’t have visible cracks or leaks, moisture can still seep through them over time due to water vapor transmission through the porous concrete. This “invisible” moisture leads to the signs of dampness listed above. 

Ignoring the problem allows more water damage to occur and makes repairs more complicated and costly down the road. 

Get ahead of the issue now by installing a vapor barrier. The AquaStop WallSeal™ Vapor Barrier is a cornerstone in our whole-home solution, ensuring that every part of your home remains dry and healthy. 

What Are the Benefits of the WallSeal™ Vapor Barrier? 

Our durable vapor barrier offers several advantages, including: 

  • Long-lasting Protection: Our barrier is made from high-quality materials that stand the test of time, offering reliable, long-lasting protection. 
  • Healthier Living Space: By reducing humidity and preventing mold growth, you create a healthier environment for you and your family. 
  • Eliminate Musty Basement Odors: The WallSeal™ vapor barrier blocks moisture and water vapor, preventing the source of that damp, humid odor. Our barrier, coupled with a dehumidifier, helps refresh basement air quality. 
  • Protect Your Possessions: Flooding isn’t the only basement moisture damage. Dampness also corrodes storage items, ruins valuables, and warps wood over time. WallSeal™ maintains a dry environment to keep your belongings safe. 
  • Enhance Property Value: A dry, well-maintained basement can significantly enhance your property’s resale value. 

To get the most out of the WallSeal™ vapor barrier, it must be installed correctly. Our certified technicians use the proprietary products and techniques perfected by Ohio Basement Authority to give you the driest, healthiest basement possible. 

How the WallSeal™ Vapor Barrier Works 

After an Ohio Basement Authority expert inspects your basement and deems the WallSeal™ Vapor Barrier necessary, it is installed along with our other basement waterproofing solutions. 

The process includes these steps: 

  • Clean and prepare walls. 
  • Securely fasten sheets of WallSeal™ to the walls. 
  • Install interior drainage and the remaining components. 
  • Install a sump pump in the basement’s lowest point. 
  • Connect interior drainage to the sump pump. 
  • Install a basement dehumidifier. 

Here is how the complete system works: 

  • If water leaks in through basement walls, it automatically runs behind WallSeal™. 
  • WallSeal™ directs leaking water to the interior drainage system. 
  • Water in the drains flows into the sump pump. 
  • The sump pump removes water collected in its basin. 
  • The dehumidifier removes any remaining basement moisture. 

When Ohio Basement Authority installs these essential water management components, you receive a professional installation you can trust.
