Compotite Holdings LLC - Composeal Membranes Information

Compotite Shower Pan a pioneer in the shower waterproofing industry since 1938, was founded in Los Angeles to manufacture and market "COMPOTITE": a patented waterproofing material substitute for lead shower pans developed by G.A. Morthland. By 1958 the company was incorporated and soon Compotite Shower Pan was included in all model plumbing codes and sold nationwide. COMPOSEAL Blue Vinyl Shower Pan was introduced in 1979 and it soon replaced "Good Old Compotite" completely by 1985 because of its popularity, ease of installation and economic price. COMPOSEAL Blue is made from high density PVC resins and calendered into a strong waterproof, puncture resistant, chemical resistant and mildew resistant membrane. It meets or exceeds the requirements of the three major plumbing codes: UPC/IAPMO, SBCCI, BOCA and the new International Plumbing Code. It also meets the ASTM and Ceramic Tile Institute requirements for non-bonded waterproof membranes. The required logos for these agencies are printed every 2 feet on the membrane for easy on-site certification by the building inspector. COMPOSEAL is sold through more than 450 tile and plumbing wholesale distributors in 100 foot rolls, 4, 5 or 6 feet wide, in 40 mil gauge ( 40/1000" or 1/25" thick). COMPOSEAL 30 mil is also available in UPC code areas. In 1992, COMPOSEAL GOLD 40 mil Waterproof/Crack Isolation membrane was added to the Compotite product line. COMPOSEAL GOLD meets the ANSI A118.10 Standard for Load Bearing, Bonded, Waterproof Membranes for Thin-set Ceramic Tile and Dimension Stone Installations & ANSI A118.12-2008 Standard for Crack Isolation Membranes for Thin Set Tile and Dimension Stone Installations. Composeal Gold is manufactured in 5 foot Widths and comes in 50 ft & 100 ft rolls and is sold through Tile Distributors across the USA.
