ROCKMAX PU100

POLYURETHAN INJECTION TO STOP WATER LEAKAGE



INTRODUCTION

Rockmax PU100 is a hydrophobic water activated injection foam grout and soil stabilization based on polyurethane. It is designed to stop water leakage by pressure injection through cracks, honeycombs, voids and/or damaged concretes. The material will react immediately when contact with water and create expansion to stop water leakage. The reaction time can be adjusted by percentage of accelerator. The cured material is semi-flexible and constant volume.

AREA OF USES

  • Crack leakage.
  • Repair construction joints.
  • Repair expansion joints.
  • Tunnel leakage.
  • Basement leakage.
  • Dam, reservoir, pipe, subway, tanks.
  • Diaphragm and retaining wall.

    • ADVANTAGES

  • Expansion more than 20 times.
  • Non toxic.
  • Can use in portable watertank.
  • Low viscosity.
  • Deep penetration.
  • Excellent bonding.
  • Easy to use.
  • Can adjust reaction time.

    • APPLICATION AND INSTALLATION

    PREPARATION

    Investigate the temperature and humidity of the site environment for determine the pot life of the mixed. Do not over mix the material more than the amount will be pumped. In case of high temperature and high humidity, the percentage of accelerator must be less than low temperature. In completely dry cracks, it is necessary to pre injection of water prior to start application.

    APPLICATION

    The mixture can be used conjunction with single line injection pumps together with metal injection packers. Holes are drilled on alternating sides along the course of the crack at an interval of approximate 20-25cm. Insert packer to the drilled ho les and start injection from bottom to top. Inspect the material injected after full cured (approximate 24 hours).

    PACKAGING

    22kg set.
    part A: 20kg ; part B: 2kg (1kg x 2set).

    STORAGE

    Storage in shade and dry condition free from frost, water, moisture and high temperature. Rockmax PU100 must be store in air tight container. Must be Protect from atmospheric moisture. Must be store in area where temperature around 10ºC – 30ºC degree.
