JOSAM Company has revolutionized the drainage industry with the PRO-PLUS® Trench Drain System. The PRO-PLUS® trench drain is available in two widths and depths and offer a wide range of grates that provide the solutions you need to meet your application requirements. With the PRO-PLUS® trench drain system a free-of-charge technical design service is offered providing hydraulic calculations, CAD drawings, quantity schedules, and product specifications.

PRO-PLUS® trench drains are manufactured using glass-fiber reinforced polyester (GRP) pressed from sheet molding compound (SMC), which is a composite of polyester resin, mineral fillers, and glass-fiber mats. SMC is a tried and tested GRP material with extremely high strength and dimensional stability. For example, SMC/GRP is more than 1.5 times stronger than polymer concrete. In addition, SMC/GRP's thermal expansion on average is 40% less than that of polymer concrete. These SMC/GRP material characteristics result in extreme rigidity and only minimal longitudinal expansion, even for wide temperature fluctuations. In contrast to thermoplastic polymers, SMC/GRP cannot be reshaped and remains dimensionally stable once heated compression hardens the material into the final product. Glass fiber reinforced polyester made from SMC is used wherever extreme conditions prevail and special degrees of durability and rigidity are called for, precisely as in JOSAM's PRO-PLUS® trench drain solutions. This product is lighter, stronger and expands and contracts in extreme temperature ranges less than polymer concrete. In addition, SMC/GRP has greater compressive, flexural, and tensile strength and less thermal expansion properties than either polypropylene or high-density polyethylene. SMC/GRP is an innovative material and is clearly superior to all other trench channel materials.

Advantages of the innovative SMC/GRP PRO-PLUS® Trench Drain material include:
  • Shatterproof and extremely resistant to abrasion
  • Frost, heat and rust-resistant
  • Lightweight
  • Non-porous structure with a smooth surface
  • Resistant to chemicals
  • Resistant to oil, gasoline, hot asphalt, and tartaric acid
  • Non-flammable
  • Free of halogens, asbestos and toxic heavy metals
  • Capable of being formed into complex shapes
  • An excellent cost / performance material
  • Recyclable
  • Complies with UL 94 HB Fire Rating
  • When using high-temp accessories, it can withstand fluid temperatures of 212ºF continuous and 394ºF intermittent
