Drytech International SA
About
Drytech International SA is a Swiss waterproofing specialist that has operated exclusively in the waterproofing sector since 1963, making it one of Europe's longest-established companies in this field. The company develops, manufactures, and applies waterproofing systems for underground structures, water infrastructure, and sewer rehabilitation. Its core product, DRYflex, is an expanding acrylic resin certified for drinking water contact that is injected into cracks, construction joints, and pipe defects to seal leaks from inside the structure without excavation or operational shutdown. The resin also consolidates surrounding soil to restore structural support around pipes. The Drytech Tank system provides permanent structural waterproofing for all underground construction using the white tank method, combining waterproof concrete with DRYflex-sealed construction joints to create a monolithic barrier against groundwater. Drycoat serves as an elastic, walkable, continuous membrane for terraces and architectural surfaces, conforming to construction details without requiring plumbing work. The sewer sealing and repair division deploys robotic injection technology that inserts DRYflex resin into joints, manholes, lateral connections, and pipe breaks from inside the pipe, eliminating the need for trenching. Drytech Engineering provides design consulting and specification writing services, supporting over 1,000 ongoing construction projects annually across Europe, ranging from dams and aqueducts to residential basements and underground car parks. The company also manufactures specialized packer equipment and mobile remote control centers for sewer repair robots, which are custom-installed on contractor vehicles.
