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.
Each of the biggest sellers – Wolfin, Cosmofin and Koster, have their own benefit and are ideal for different situation. Wolfin products offers waterproofing solutions for the greatest number of situations; from roofs, balconies and terraces, walls, planter boxes, basements and cellars, expansion joints, water tanks, lift pits, and fountains. Cosmofin can be used in all of the same situations, except for ponds and fountains. Finally, Koster can supply more niche areas such as retaining walls, basements, lift pits, cellars, water tanks and swimming pools.
