Why Investing in Crawlspace Waterproofing Is a Smart Idea


Are you investing in crawlspace waterproofing? You’ll be faced with various decisions prior to beginning the waterproofing process. One of these decisions is which vapor barrier to use for your crawlspace.

Many homeowners get confused when it comes to choosing a vapor barrier for their crawlspace. With so many options available in the market, the decision-making process can quickly become overwhelming for homeowners who are not familiar with vapor barriers or crawlspace waterproofing.

The following are some questions to ask when going through the selection process. Answering these questions ought to make the selection process easier for you.

How Thick Is the Vapor Barrier?

Many homeowners go with the thinnest vapor barrier that meets their local building codes. This is because thinner vapor barriers are often more affordable. However, this is the wrong approach to take when it comes to selecting the thickness of the vapor barrier.

It is important to consider factors such as durability and moisture resistance when you consider the thickness of the vapor barrier. In general, a thicker vapor barrier will provide greater tensile strength and therefore greater durability. This is especially important if you will need to access your crawlspace for utilities or storage. You will need a vapor barrier that will not tear or puncture easily.

What Is the Vapor Barrier Made Of?

Vapor barriers are generally made from a plastic known as polyethylene. This thermoplastic polymer is widely used to make a variety of plastics. However, the particular composition and construction of different vapor barriers varies. While some vapor barriers are made from virgin polyolefin resins, others are made from recycled plastic that is blended and combined to make the sheets.

The problem with using recycled plastic is that the final product is more brittle and is therefore more likely to weaken over time. Vapor barriers that are made from virgin polymers offer greater structural integrity and durability. It is therefore worth taking the time to learn more about the manufacturing process of the vapor barrier you’re considering for your crawlspace.

What Is the Vapor Barrier’s Permeance Rating?

The lower the permeance rating of the vapor barrier, the better it will be at keeping your crawlspace dry. The permeance rating indicates how resistant the vapor barrier is to moisture. You should therefore pick a vapor barrier with a low rating.

Consult a crawlspace waterproofing professional to help with the selection process and ensure you select the best vapor barrier for your space.
