A moisture problem in your crawl space can attract mold, dust mites, insects, and other pests. Excess moisture can also cause wood rot and damage insulation. Mold spores and dust mite droppings can travel up from your crawl space into your main living space and make allergies and asthma symptoms worse.
Ohio Basement Systems can help solve and prevent these problems by lining the ground and walls inside the crawl space with a vapor barrier to help keep out moisture.

But it’s down below the floor, not where I live
Wrong. Up to 40 percent of the air we breathe on the first floor of our homes comes from the crawl space or basement!
This air gets into the first floor because of what’s called the stack effect (think of a chimney).
Warm air in the upper levels of a home rises and is expelled, typically through the attic. But nature abhors a vacuum so that air that’s expelled must be replenished.
The source? Some of it comes in through windows and doors but much of it is sucked up from the crawl space or basement.
Telltale signs of excessive crawl space moisture
- Standing water or mud on dirt floor after a heavy rain
- Efflorescence on crawl space walls
- Signs of rot and rust in crawl space
- High radon levels
- Unpleasant musty odors
- Respiratory discomfort, headaches, and illnesses, such as allergies and asthma
- Insect and other pest infestations
- Mold and mildew on walls and floors of first-floor closets
- Peeling paint on home exterior
How a crawl space vapor barrier helps
A CrawlSeal® barrier blocks moisture from evaporating into the crawl space, keeping it dry and reducing heat loss.
A vapor barrier slows or prevents the evaporation of ground moisture into the crawl space air. If coupled with a waterproofing system, moisture and water can be expelled from the crawl space before it can cause problems. This will curb issues with rot, rust, mold, and odors, and insects and other pests will have a difficult time getting inside.
A vapor barrier, by its nature, resists the passage of air. By stopping air movement from the ground, it can also turn your crawlspace into a semi-conditioned space – one that is close to the temperature of the living spaces above. When that occurs, your floors feel warmer in winter and your energy bills go down.
A vapor/air barrier can also slow or block most of the movement of harmful gases, such as radon, from the soil. Coupled with a radon mitigation system (in the event that radon is present in higher than acceptable levels), a vapor barrier can significantly reduce radon levels in the home.
The CrawlSeal™ vapor barrier
CrawlSeal™ 20–mil vapor barrier is puncture and tear-resistant. An anti-microbial agent is blended into the liner to kill mold and bacteria.
For a vapor barrier to be effective in the long term, it must be durable. That’s why Ohio Basement Systems developed the CrawlSeal™ crawl space liner.
Made of a 20-mil 7-ply sandwich of high and low-density polyethylene with polyester-cord reinforcement, the liner is treated with an antimicrobial finish that protects against mold and mildew growth on or under the CrawlSeal™ liner. There are also 10 mil and 12 mil vapor barrier options for certain applications.
The CrawlSeal™ liner significantly outperforms thin and easy-to-tear 6-mil liners that are commonly used as vapor barriers.
The CrawlSeal™ liner is also UV resistant as opposed to 6-mil liners that typically crumble and disintegrate in a short period of time.
