Water Control using polyurethane resins Óscar Pro

Actually it is possible to use a wide range of techniques and products to control water ingress into underground and mining works. There are many products for waterproofing, consolidation, sealing, bolting, crack and joint repairing, bonding and cavity filling. Unexpected water ingress during tunnelling usually escalates project costs and important delays. In this case the injection systems based on dual and single component polyurethane resins, are cost-effective. Appropriately engineered resin injection can transform running sands to the consistency of a sandstone and water-bearing gravel to a solid conglomerate. There is no single resin that will suit all conditions. If the incorrect resin is chosen it may result in a performance that does not meet the requirements. The polyurethane injection systems assure high performances in the solution of problems in geotechnical field and waterproofing, in tunnelling, underground works and civil engineering in general
