Am-cats provides a crew to install your treated wood multi-decking system to Approved plans.

All treated wood is now “ground contact”. “Ground contact” has a high chemical retention level and can be placed directly on or in the ground. This provides better protection against rot and decay. With pressure-treated posts, the rot will be slow. We have three ways to solve the rotten post problem. First, the posts should be set on top of a bed of coarse gravel 3 to 6 inches deep, so the base of the post is in contact with the gravel. Concrete should be poured around the post – no concrete under the post.  Anyplace where wood meets the ground or concrete, the lumber must be pressure treated. For additional moisture protection, a gasket or strip of closed-cell foam can be installed between the concrete foundation and the sill plate.

  Decking can be installed with hidden fasteners to create a clean-looking surface that is smooth to bare feet. Hidden fasteners can be used with composite, vinyl, cedar, or other exotic hardwood material, and comes with extra cos. for the decking boards, many agree that screws perform better than nails. They have better tensile strength and will be less likely to pop out, which is a common problem in decking. Many also agree that nails are better used for the frame of the decking.

  A Treated Deck costs between $3,500-$30,000 per level and size of decking. All material used is charged separately on the material invoice used for the project.
