Trelleborg Slovenija d.o.o.
About
Trelleborg Slovenija d.o.o., headquartered in Kranj with a secondary facility in Ptuj, Slovenia, is a rubber and polymer products manufacturer with roots dating to 1920 as Sava, now part of the global Trelleborg Group. The company employs 434 people, generates approximately 90 million EUR in revenue, and exports to over 80 countries. Its water infrastructure portfolio centers on trenchless pipe rehabilitation: the DrainPacker short liner system uses styrene-free silicate resin on CRF+ glass fiber mats for DN 35-1,200 sectional repair across all pipe materials, backed by German Approval Z-42.3-385 and exceeding 100,000 annual installations worldwide. CIPP lining systems cover DN 30-1,600 with UV and hot water/steam curing options. MESeals provide mechanical internal joint sealing for sewer pipe connections. SprayPoxy applies epoxy coatings for pipe rehabilitation and corrosion protection, while Powercutter robotics remove intrusions and reinstate lateral connections in rehabilitated pipes. The PLUGY and PLUGSY pneumatic pipe plug lines span 40 mm to 1,800 mm diameter with pressure ratings up to 30 bar, including egg-shaped, high-pressure, chemical-resistant, and gas variants. Rehabilitation packers come in long, flexible, lateral, and multiple-size configurations. Beyond water infrastructure, Trelleborg Slovenija produces Sava-brand conveyor belts, emergency rescue equipment including lifting bags up to 100,000 kg, and injection-molded elastomer components for automotive and industrial applications.
