Protecting Your Crawl Space From Moisture Complications

Damp crawl spaces are usually vulnerable to mold attacks. Any wooden support structures in such crawl spaces are also vulnerable to both rotting and termite attacks, something that may end up compromising the structural support system of a home.

While it is possible to dry a crawl space by taking advantage of dehumidifiers and large electric fans, the fact that most crawl spaces are hard to reach, poorly ventilated, and dark usually makes for a not-so-easy drying process. Making sure that you protect your crawl space from moisture invasion is the best option as far as preventing crawl space moisture complications is concerned. The following are crawl space protection tips that will come in handy in helping you do so.

Install an effective gutter system

Rainwater usually finds its way to the crawl space by seeping through a home's foundation. This problem usually arises in cases where rainwater accumulates around the home's foundation, leading to an increase in hydrostatic pressure that not only causes foundation cracks, but also leads to a damp crawl space. This is something that can be prevented by simply improving the drainage around the home.

An easy way of preventing the accumulation of rainwater around your home's foundation is to install a good gutter system. Maintaining the system by ensuring that any worn-out hangers are replaced and that any debris is removed will go a long way towards reducing the hydrostatic pressure around your home's foundation. Sealing any gutter holes, adding more hangers and applying a corrosion-proof coating on the gutters will reduce water spills and is something that is also recommended.

Add insulation to your foundation walls

When waterproof insulation is used on a home's foundation walls, it usually does more than reduce the rate of heat loss. The foundation wall insulation being waterproof usually helps to reduce the risks of water seepage and as a result reduces crawl space water infiltration. For the best results, taping the seams of the insulation is advisable. Caulking of the seams will also help and is thus something you should consider. You can also improve this moisture shield by adding a protective plastic sheeting on the interior of your home's foundation walls.

 Use a moisture barrier

If a crawl space falls below the water table, ground water can also infiltrate the space. To prevent this from happening, you should install a thick moisture barrier on the crawl space's floor. Using continuous sheets of the moisture barrier is advisable as it helps eliminate the need for joining the sheets. This usually helps to reduce possible water-seepage points.
