Spatial solution to cushion the crawling: Polyethylene vapor barrier

If you have standing water on pipes and concrete wallscrawlspace, then you have a general problem. Ventilation holes are designed to let moisture out of the crawl space, but they usually don’t work except in dry climate locations. In fact, in humid summer conditions, they often make matters worse. Damp air carries moisture which condenses on cold walls, pipes and even under floors.

The best solution is to completely close the vents (or remove them in the case of new construction) and control the humidity in the crawl space by other means. The photo illustrates some key concepts. However, local and regional conditions vary and the exact details of this system may not work in all crawl spaces. Be sure to get approval from your local building inspector before taking any action.

  1. Create good drainage around the house to prevent rainwater from entering the house. A sloped floor about 1/2 inch/foot from your home is often the best thing you can do to reduce humidity in the crawl space.
  2. Cover the crawl space with moisture-proof polyethylene plastic. Overlap all the seams and glue them together. And put the plastic piece about 6 inches on the wall and fix it. Tie the plastic with a landscape canvas stake to hold it in place. Chances are someone will have to slip into the crawl space later to fix a pipe or run a new cable. A few holes won’t make a difference in performance and they will drain into puddles if heavy rain or leaky pipes leave water on the plastic.
  3. Cover exposed foundation walls with 1-1/2″ hard moisture resistant insulation. This not only insulates the walls, but also prevents moisture buildup in the concrete from entering the crawl space. We used the Thermax brand (available at sawmills) of polyethylene vapor barrier because it does not require an additional fire barrier. Other types may require drywall sheathing.
  4. Insulate the end joists. We used hard insulation and gaskets in place to prevent air leaks.
  5. Wrap the inside of the foundation wall with a layer of 6 mil plastic and galvanized corrugated iron to both block moisture and act as a termite barrier. There is no foolproof solution to termites; Building codes may require different details for termite control in your area.

How thick should vapor barrier be?

Vapor barriers should be at least 6 mil in thickness to effectively cover the area and create a moisture barrier. Triangle Crawl Space Solutions uses both a 6 mil material for simple vapor barrier installation and a thicker more durable 12 mil vapor barrier material depending on the budget and needs of the home.

What side of wall does vapor barrier go?
