AVINJECT 1C MULTIPURPOSE

AVINJECT 1C MULTIPURPOSE

One component, solvent free, polyurethane injection system, injected with a two-component pump with water as the second component. It produces a tough, flexible polyurethane foam or an elastomeric gel or soft gel, depending on the amount of water added. Possible applications: expansion joints, heavy water leakages, screen injections

  • Heavy water leakages:  Because of the high reactivity in combination with water, Avinject 1C Multipurpose is used for shutting of Heavy water leakages (up to 5 ma per minute).The ratio to be used is 1:1 or pure water.
  • Expansion joints Because of the foaming capability Avinject 1c Multipurpose, a good flexibility of the product as well as a good adhesion to the aggregate, it is used for expansion joints. The ratio to be used Avinject multipurpose to water is 1:4 or 1:5
  • Gel membrane screen injection Because of the low viscosity of the water/polymer mixture, it can be used as a liquid, but solidifying gel membrane applied to the positive side of a concrete structure from the negative side. Ratio to be used Avinject 1c multipurpose & water is 1:10. The gel mixture will fill the voids from the aggregates like sand etc.} Behind the wall to avoid that water will come into the wall construction. The procedure is drilling through the wall and pumping the Avinject 1c multipurpose—water mixture via packers.
  • Masonry walls screen injection Because of the low viscosity in combination with a relatively long pot life can be used in masonry walls as a vertical barrier to fill the voids/joints in masonry walls to avoid that water comes through the voids to the surface of the wall. Ratio to be used is 1:12/13 The procedure is drilling holes to 80 % of the wall thickness or until 5cm from the back of the wall and pumping the Avinject 1c multipurpose water mixture via packers in the wall.
  • Gel encapsulation Because of the low viscosity in combination with a good adhesion it is used for the gel encapsulation method where voids are filled with a jelly material (e.g. delaminated concrete slabs etc.). Ratio to be used is 1:10
  • Oakum technique Because of the reactivity with water it is used for the activated oakum technique where oakum or any other kind of carrier material is soaked in pure Avinject 1c Multipurpose. The oakum and the Avinject 1c Multipurpose are applied into any void where small water leakages can be a problem (pipe outlet through walls etc.).
  • Injection hoses Because of the low viscosity in combination with a relatively long pot life it is used for injection hoses being installed in new structures for immediate waterproofing or for later waterproofing. Ratio to be used is 1:12/13
