SikaInject®-102

(former TPH.® PUR-O-STOP)

Polyurethane based injection resin for stopping of flowing water.

SikaInject® 102 is a PU-based single-component, low viscosity, water-reactive injection resin. It cures to form a closed-cell, dense, but slightly flexible foam.

  • Reacts with the water present in the injection area with strong foam formation.
  • Foam factor up to 75 times (free expansion)
  • Adjustable potlife; by adding up to 10% SikaInject® 102 Cat (formerly known as TPH PUR-O-STOP Catalyst) to the SikaInject® 102 PU-resin, the reaction can be accelerated (e.g. cold water)
  • Can be injected by 1-C-pumps (pneumatic or electric)

Usage

  • Stopping of high water intrusions in cracks, joints and cavities in concrete and masonry.
  • Waterstopping in special applications such as pile walls, anchor heads and microtunneling.
  • Ground and rock consolidation as well as numerous other waterproofing applications in civil engineering, tunneling and mining construction.

Application

Application Information

Mixing ratio

Adjustable - up to 10% of catalyst can be added

The mixture of resin and accelerator lasts approx. 8 hours, where a skin can form on the surface (reaction with air humidity). Remove skin from surface; do not mix back into the liquid. 

Ambient air temperature

+5 °C min. / +35 °C max.

Substrate temperature

+5 °C min. / +35 °C max.
