Tests conducted by the United States Department of Agriculture (USDA) wea4.gif (12161 bytes)on wood stakes treated with Osmose CCA preservative have shown a resistance to termite and decay damage for over 40 years. This independent and impartial testing agency predicts a service life for wood treated with Osmose preservative of 5 to 10 times longer than untreated wood.

How wood is treated

The nine steps to quality wood treating:

  1. Common species of wood are harvested from managed forests with minimal disruption to the environment.
  2. The logs are transported to sawmills where they are cut into lumber, timber, poles, posts, etc.
  3. The lumber, timber, and plywood are graded, kiln dried, and then moved to the pressure treating plant.
  4. The wood products are placed in a treating cylinder which is designed similar to the hull of a submarine, capable of withstanding high pressure (see graphic above).
  5. The cylinder is sealed and a vacuum is applied to remove air from the wood cells.
  6. A mix of OsmoseŽ high purity oxide CCA preservative and water is forced under high pressure into the wood.
  7. After the wood has absorbed the proper amount of preservative, all excess preservative is removed from the cylinder and returned to storage tanks for reuse and recycling.
  8. The wood is removed from the cylinder and tested for preservative penetration and retention.
  9. The wood is stored on an EPA approved containment area while a preservative reaction takes place which bonds the preservative components to the wood making it highly leach-resistant.

Properly processed CCA pressure treated wood products are clean, odorless, and safe to use in a wide variety of applications when used as recommended. CCA pressure treated wood, through preservation technology, saves trees, requires less energy to produce than alternative building products such as concrete, steel, and plastics, and is manufactured with renewable and recyclable ingredients.

CCA pressure treated wood is often the choice for products that allow people to enjoy nature without damaging the habitat. Such projects include camping and viewing platforms, walkways, pedestrian bridges, dune crosswalks, fencing, nesting platforms, and many others.

Let us help you build a system that will bring a sense of accomplishment. We're here to help make that project strong, safe, economical and yet still blend into a natural habitat.wea11.gif (24735 bytes)
