Understanding Foundation Wall Wraps: How They Work and Why They’re Necessary

The home you and your family live in represents one of, if not the, biggest investments you will ever make. Just as a savvy stock broker helps an investor protect his investments, you too need things in place to protect your home investment.

From the ground up, the foundation of your home is a great starting point when considering different solutions to protect your home from the ever-present threat of water damage. Homeowners that invest in waterproofing solutions for their foundations are taking proactive steps that can not only protect their home’s foundation but can also improve indoor air quality, enhance energy efficiency, and increase the home’s value!

You can check all of those boxes by installing something called a foundation wall wrap. Wondering how these work? Hopefully, by the end of this article, you will have a better understanding of what this technology is, how it works, why you need one, and how to choose the right product for your home.

What is a Foundation Wall Wrap?

As the name implies, a foundation wall wrap essentially ‘wraps’ the walls and floor of your home’s basement or crawlspace as a means to protect your home from water damage seeping up through the foundation wall.

Just as you would place items into a resealable plastic bag to protect them from water, this technology seals the foundation walls and floor of your home to protect them from the same.

Simply put, a wall wrap acts as a waterproof barrier that keeps water from getting into your home through the foundation walls.

Why You Need a Foundation Wall Wrap

Perhaps the single biggest reason to install a wall wrap is to eliminate basement flooding and moisture issues.

This technology is ideally suited for;

  • Protecting your home’s structure from water damage
  • Addressing high humidity levels in your home
  • Addressing poor insulation issues in your home

It’s like having an active insurance policy in effect 24/7/365 to protect your home’s foundation walls.

Advantages of Using a Foundation Wall Wrap

In recent years we have become more aware and more diligent in pursuing improved air quality in every area of our lives. A foundation wall wrap is a great way to do just that in your home!

By preventing water damage, you are also preventing moisture build-up—moisture which could lead to mold growth, complicating any efforts to improve the indoor air quality of your home.

A home with such protection in place operates more efficiently and increases in value.

Wall Wrap Types

Now that we know what a foundation wall wrap is and why we need one, let’s take a look at the different types and give you a short breakdown of each one.

Polyethylene Foundation Wall Wrap:

High-Density Polyethylene Plastic (HDPE) foundation wall wrap (or wall membrane as it is often referred to) is a high-density black plastic sheeting that is usually affixed to the outer walls of your home’s foundation. Interior installations are also common.

This product features a dimpled design that allows the sheeting to essentially breathe as the backfill material is being applied. This feature also allows any incoming water to be successfully diverted to a weepage point located along the foundation wall’s outer perimeter.

It can be installed with or without any additional waterproofing agents and is suitable for almost any climate.

This sheeting can be backfilled immediately after installation when choosing the exterior installation method.

Bituminous Foundation Wall Wrap:

A bituminous foundation wall membrane is also known as asphalt. This sticky, black, and highly viscous liquid is a form of petroleum that maintains high waterproofing qualities.

A bituminous membrane is perfect for waterproofing basements or any below-the-surface structures.

Hybrid Foundation Wall Wraps:

Hybrid foundation wall wraps can get a bit technical so let’s just see what one of the industry leaders has to say about this foundation wall wrap solution.

From an April 2015 article in Waterproofing Magazine;

Hybrid below-grade water-proofing membranes combine active polymer barrier technology with conventional passive-bonded product technology to counter failure trends. By incorporating multiple barrier materials in a single waterproofing membrane, the new active polymer hybrid membranes compensate for the shortcomings of traditional materials regarding workmanship and dependence on perfect installation to prevent failure. By recognizing modes of failure in traditional membranes, new active products are being engineered to prevent failure by combining different material layers that increase the failure modes that must occur at a specific location for water ingress to occur. The common trend among all emerging active waterproofing systems is a recognized need to adapt to current construction techniques and perform at a higher level to prevent water ingress.

The hybrid wrap provides a multiple-layer waterproofing membrane for your home!

Choosing the Right Option for Your Home

Knowing a bit more about foundation wall wraps and how they affect your home is just the beginning. Now you need to assess your home’s current condition and decide on which type is going to provide the solution you need.
