The Crestwood Story

Pressure treated wood wall above ground pools are an attractive, safe and long lasting alternative to the standard metal wall above ground pool. Crestwood Pools uses only the finest Grade 1 Southern Yellow Pine in all of its pools. This stringently graded type of lumber is not only the most easily and completely treated wood available, but also, selected from the best parts of the tree. Only boards that meet strict guidelines for knot size and quantity, limited amount of wane (bark remaining along the edge of the board), grain consistency and structural integrity can be graded as #1. Although only #1 Lumber is used, Crestwood Pools acts as the final inspector monitoring the moisture content, bowing, crooking and surface appearance.

The pressure treatment process begins by completely immersing lumber in a pressurized tank filled with a water based solution of CCA. As wood is exposed to moisture it swells similar to a sponge. When most commercially available pressure treated lumber is exposed to sunlight and lower humidity it begins to dry out and shrink. These tendencies of the treated lumber are often considered undesirable. Drying of the wood (and the accompanying shrinkage) is what contributes to bowing, warping and crooking of the treated lumber. These characteristics would be unacceptable to above ground pool wall construction. To eliminate any potential problems, Crestwood Kiln Dries (dries in a large oven) all its lumber and continually monitors its moisture content. By doing so, Crestwood can insure stable wooden components that have been dried to their equilibrium moisture content. After drying, the boards are again inspected for warping, twisting, bowing or cracking.

All pressure treated wood will weather and show signs of checking with time. This natural aging process will not affect the woods' useful life or affect its' warranty. However, customers should be advised that an application of Wolman Brand Stains or Water Repellent Coatings every two years will reduce the number of check and cracks, as well as retard the weathering process.
