POLEPOX-PU INJ300
Flexible polyurethane foam, one component, low viscosity, injection resin.
One-component polyurethane, hydrophobic resin, which reacts with water to produce a flexible grout suitable for waterproofing and sealing cracks and joints of concrete surfaces, and for effectively stopping water leaks. Recommended for use on concrete elements subject to structural movements. Application is by one-component injection pump.
RECOMMENDED FOR
Stopping water leaks in such structures as:
- Foundations.
- Below-grade structures, e.g. garages, tunnels & underpasses.
- Sewage systems.
- Tanks.
- Waterways & dams.
FEATURES & BENEFITS
- Effective sealer of cracks & voids in concrete, especially in joints.
- Of low viscosity: Deep penetration with minimal pressure.
- Produces a flexible & completely hydrophobic foam.
- Easy to apply: One-component with a very reasonable pot-life.
- Highly resistant to fungi and other microorganisms.
- Friendly to the user and the environment: Contains no solvents or propellant gasses - safe to store, transport and use.
APPLICATION PROCEDURE
- Surface Preparation: Clean the substrate using a high-pressure washer, if possible. Remove oil, grease and wax contaminants. Cement laitance, loose particles, mould release agents, and cured membranes must also be removed. Large voids can first be sealed using CS 100 - EJS15.
- Mixing: First, mix POLEPOX-PU INJ 300 with POLEPOX-PU INJ 300 Catalyst. The proportion of catalyst added ranges from 1% to 10%, subject to temperature and humidity of the substrate. Prior to application, the mix should not be subjected to humidity; the container must be covered to avoid a premature start of the reaction process.
- Application: Starting from minimum, gradually increase pump pressure until reaching the desired rate of injection. Its level depends on the size of the cavity to be filled and the condition of the substrate in general.
