One component, non-phthalate, non- solvent, VOC free, low viscous polyurethane injection system ideally suitable for ground improvement with water ingress; permeation grouting in ultra fine cavities; water-stopping in rock. Crack injection/water leaks in concrete and masonry structures. Reaction with water yields a durable rigid closed cell polyurethane foam. To be injected with a one-component pump.

HOW DOES 115 ECO WORK?

115 ECO is the next generation chemical system for deep penetration and extreme high-water ingress situation. Reaction with water yields a durable semi-flexible polyurethane foam. The formation of CO2 makes the resin penetrate very well into the fine cavities and cracks. A good compression strength is obtained in a very short time. Free expansion: +3000%.

The reaction speed can be accelerated by adding 2% to 10% lC CAT. Make sure to mix the resin and catalyst very well. lC CAT is ADR free.

Application

  • Leak sealing in foundation and permanent structures.
  • Leak sealing for deep tunnels and shaft excavation.
  • Leak sealing in sewers and water retaining structures.
  • Ground improvement and permeation grouting.
  • Cavity filling and fissure grouting.

115 ECO is very hygroscopic and packed under dry atmosphere. Use opened containers as soon as possible or recap under dry nitrogen. Pumps should be cleaned with MEK, Acetone, or any solvent cleaning agent for cleaning of polyurethane injection pumps.

STORAGE

To avoid problems, it is very important to understand that these materials are both temperature and moisture sensitive. Therefore, materials should be stored in an area with temperatures not exceeding 30°C or not lower than l0°C. Shelf life is one year. Avoid partly used drums.
