Two kinds of moisture problems can occur in the space under decks: moisture from humidity and flooding. If your home is located atop a steep hill or near a creek or river, flooding can occur.

Some decks are only capped on top, which can cause all sorts of trouble when excess moisture from the hot tub gets under or between the boards. And not all fully capped boards perform in the same way, either.
When your deck is over water or in particularly wet areas, allow additional clearance. A vapor barrier is necessary when deck installation is under 16 above ground to avoid moisture absorption on the decks underside.
Under-deck ceiling systems provide an all-in-one drainage and ceiling finish that is particularly suitable for areas beneath a deck that are high enough off the ground to provide a sheltered outdoor living space below. Special framing and moisture-protection measures can provide mounting points for overhead light fixtures and ceiling fans.
How to test moisture content in wood decks? Have you ever wondered if a wood surface is dry enough to paint or stain after a rainy couple of days? WHAT is this, and WHY do you want it under
Composite Decking. If there is mold on your composite decking, youve got a different mold removal problem altogether. When composite materials first came out, mold was a major problem caused by the use of certain recycled materials in the wood that fostered mold and mildew growth.

If the natural look of wood is tops on your list, use cedar for wood decking. The heartwood of the tree the deeper colored red part, not the white sap part is rot resistant.

I'd put in place a way for air to costantly move in and out. Humidity pooled there can certainly ruin wood decks but the way the wood is sealed has lots to do with it's stability.
When it comes to working with wood, it is particularly important to consider moisture levels. Installing outdoor tile over wood deck can potentially create a situation where moisture gets trapped beneath the wood deck tiles. With enough moisture, wood becomes vulnerable to decay and rotting.

Any water or moisture under a deck needs a means to escape or it has the potential to wreak havoc with the wood deck components and decking boards and become a breeding ground for moisture and mold to create rot and and decay.
Wood decking is subject to dimensional changes as the moisture content in the wood fluctuates with humidity in the air. Swelling, shrinkage, checking, and other movement of individual pieces are normal occurrences in wood decking.
The moisture content of air-dried decking depends on how much moisture is in the local environment and how long the wood has had to adjust to it. Thermally modified decking is the driest, with around 7% or 8% MC.
Rather than have a mound of exposed earth under the deck that would take in, and disperse through evaporation, a lot of moisture. Have a plastic liner on the ground to shed any water that got under there.
After steel and wood, concrete is one of the most common types of decks specified in the roofing industry. The material makes up 13 to 14 percent of the new and retrofit low-slope construction market, according to the National Roofing Contractors Association NRCA 20152016 Market Survey.
