Take the 1:5:10:365 challenge: Do one thing – for 5 to 10 minutes – 365 days a year to make our home and planet environment better.

1:5:10:309 EcoTip: A radon gas mat system is sometimes installed under a concrete slab before it is poured to help control radon gas. If you have a crawlspace the same gas mat system can be installed on top of the crawlspace soil with the gas mat underneath a polyethylene moisture barrier to keep the radon exiting the crawlspace and entering the home. Other types of gases such as water vapor and pesticide treatments also seem to be controlled well by the gas mat systems.

Instructions and materials for the installation of a radon gas mat system under a slab foundation are available at: http://www.radonpds.com/Instructions_SM/Instructions_SM.htm. Using it in a crawlspace under a soil mat follows the same basic steps except the soil mat substitutes for the concrete.

Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet.

1:5:10:050 Tip: Placing a layer of polyethelene plastic on the surface of the soil can reduce crawlspace moisture levels ten fold. The barrier only helps with water vapor.

If you ever have standing water in your crawlspace you need tomorrows 1:5:10:365 tip.


Additional Information

Adding a soil membrane can go a long way toward keeping moisture from damaging a home. The following video of an installation is from Matt Leech at www.crawlspaceinfo.com

Crawlspaces can be dangerous places. During my career I have inspected over 1000 crawlspaces. Many had conditions that were extremely dangerous. Keeping your crawlspace clean and dry with the soil isolated from the building can go a long way towards making crawlspaces safer.

Here’s a photo from Matt of a completed installation.

If you don’t know how to safely enter and inspect a crawlspace, you should leave it to professionals.

Tomorrow’s post will discuss sump pumps – a necessity if your crawlspace is taking on water.
