TRADECC PC Leakinject UNI 6816 E - Foaming Polyurethane Injection Resin

Application

Stage 1 stemming of water ingress through joints, non-structural cracks, voids and defects within concrete structures and steel piled walls.

Description

A foaming polyurethane injection resin that reacts with water to form a rigid, hydrophobic seal against water ingress. The resin reacts quickly with water and expands to produce an open-cell, rigid foam that is ideal for stemming water ingress at defects in concrete structures and steel piled walls.

PC Leakinject UNI 6816 E is a two-part product with a low viscosity and a fast reaction time with water, making it perfect for Stage 1 stemming of leaks, even where there is a high flow of water or significant levels of hydrostatic pressure. PC Leakinject 2K Flex 6811 LV or PC 509 Z Acryl can then be used to fully seal the defect.

In contact with water, PC Leakinject UNI 6816 E creates high volumes of carbon dioxide that rapidly expands the resin to produce an open-cell, rigid foam that stems water ingress at joints, cracks, voids and defects within concrete structures, as well as sealing water leaks through steel piled walls.


Features and benefits:

  • Forms a hard, high-strength seal within the structural crack or joint.
  • Penetrates deep into fine structural cracks.
  • Has a minimum free expansion of 1700% – 2200%.
  • Does not shrink after curing.
  • The reaction speed can be controlled by adjusting the amount of catalyst that is used.
  • Chemically resistant against water, weak acids and alkali, mineral oils, fungus and bacteria, ground water, sea water and petroleum products.


Newton ReSeal System:

The Newton ReSeal System consists of a range of Newton’s advanced concrete repair mortars and injection resins to seal structural and non-structural cracks and defects, whether they are dry or leaking large volumes of water.

The products in the Newton ReSeal System can be used to repair a number of defects, including spalled and broken concrete to walls and pillars, road repairs, and cracks and honeycombing to concrete basement wall, soffits and floors.


Suitable substrates:

  • Concrete;
  • Steel piles.
