Polyurethane injection resin, swellable
HydroBloc PU 500, the injection resin with a self-healing effect! Upon contact with water (after curing), the resin increases its volume by over 150%. HydroBloc PU-500 compensates for changes in the joint cross-section even years after injection. Classic rigid resins without a swelling effect cannot do this.
Areas of application for HydroBloc PU 500
- Joints
- Cracks
- Gravel pockets
- Injection hoses
PU-500 is a classic 2-component resin. The mixing ratio of the two components is 1:1 by volume. Due to the long pot life, the material can also be processed with a 1-component pump.
The pot life is approx. 70 - 100 minutes at 20°C; by adding activators (HydroCat 508 and HydroCat 509), the setting time can be shortened to 120 seconds, thus also allowing for the stopping of water flowing under pressure.
