Projex Group was founded in the late 1980s by Jim Kornmehl in order to supply the Wolfin Waterproofing System to the Australian market. As the demand for the best quality waterproofing system grew, so did the range of Projex Group products. Today they supply Wolfin Membrances, Cosmofin, Shockmat, Link-Seal, Koster, UGA and Sub Ballast Matting.
