Understanding Moisture Content and Wood Movement ...

3. Moisture content of the wood at delivery. The only way to accurately predict wood movement is to know the MC of the material when you receive it. Moisture content is measured using a moisture meter. Failure to check your delivered material means you have no chance of anticipating movement problems.

Wood vs. Composite Decking: Let’s Compare

Invented in the late 1980s, wood-plastic composite decking (also called “composite wood decking”) is made of wood fibers encased in plastic. Composite decking is readily available at big box home improvement stores like The Home Depot and Lowe’s, as well as local lumberyards throughout the U.S.

Plastics & Composites Moisture Meters - Finna Group

Plastic films, powders and pellets are typically very low in moisture content. Finna Group has excellent plastic moisture analyzers that are up to the task.


Very low moisture content is required when processing wood and (MC) thermoplastics into WPCs, i.e. the wood component is normally dried to very low MC

How to Solve Moisture Problems Under Your Home | Today's ...

For extreme moisture problems, consider taping the seams in the plastic together, block the outside vents, and install a dehumidifier in the crawlspace to remove excess moisture from the air. Good luck with your project,

Moisture Meters - Complete List of Moisture Meters

Moisture Meters Models. Shore Durometers , or hardness testers, are used to determine the hardness of a material to deformation. Hardness measurements quantify the resistance of a material to plastic deformation.

Moisture Barrier and Underlayments: Don’t Leave It Out!

Floating Floor Installations – When installing laminate or other floating floors over cement, VCT, ceramic tiles, or kitchen vinyl, use 6 mil poly sheeting plastic as the moisture barrier. Omit plastic when covering bare wood subfloors thereby allowing the subfloor to breathe. Some underlayments have a built in moisture barrier. These are typically used for floating floor applications.

Moisture Barrier is a convenient and effective vapor blocker designed specifically for small to medium-sized flooring jobs. At just 100 sq. ft. per roll, Moisture Barrier eliminates the hassle of dealing with a giant sheet of folded plastic.

Moisture Test! Water & Wood Don’t Mix - Lumber Liquidators

The plastic film test can also be "accelerated" by using a heat source such as a 40 to 60 watt light bulb safely placed 18″? above the plastic. PHENOLPHTHALEIN TEST: This moisture test uses a 3 percent phenolphthalein solution (fig1) in water-free ethyl alcohol. Dime sized holes,1/4-inch deep, are drilled in various areas of the slab, particularly around walls.


Wood-plastic composites (WPCs) are used in a large variety of applications, most of which are for outdoor applications, e.g. decking, railing, and fencing (Smith and Wolcott 2006). When WPCs are used outdoors , they will be subjected to a climate with moisture- and temperature fluctuations, as well as decay fungi and ultra violet (UV) - radiation.

Crawl Space Vapor Barrier Myths and Problems

During construction, the vapor barrier is laid on the ground and 4″-6″ of pea gravel is dumped on top of the plastic. During the rainy season, water comes in from the walls and the ground floor and pools on top of the vapor barrier.
