LOW VISCOSITY EPOXY INJECTION RESIN SYSTEM

Surface preparation
Clean the surface and remove any dust, unsound or contaminated material, plaster, oil, paint, grease, corrosion deposits or algae.

Oil and grease deposits should be removed by steam cleaning, detergent scrubbing or the use of a proprietary degreaser.

Blow the cracks and treated surface with oil free air to ensure complete removal of all dust and loose particles. Ensure that the surfaces are blown dry.

In the presence of running water, please refer to the SpECinject PU injection resin system.

Fixing Injection Packers
The injection packers shall be inserted into pre-drilled holes at intervals along the length of each crack. The distance between each packer shall be close enough to ensure that the resin will penetrate along the crack to the next point of injection.

The surface of the cracks between the packers shall be sealed with a thick band of SpECcoat BC, typically 50mm wide x 2mm thick. Cracks that go all the way through a wall or slab must have packers located on both sides with those at the back placed at midway points between those at the front.

SpECcoat BC shall be allowed to cure for 8 hours at 20°C but at lower temperatures, the curing time will be extended and the applicator should ensure that the surface sealant has adequately cured prior to continuing. One end of the injection hose shall be attached to the lowest packer on vertical cracks or to either end of the horizontal cracks.

If alternative methods are proposed then please contact SpEC Technical Department for their comments.

Application
Thoroughly mix the entire hardener and base resin contents until the liquid becomes clear.

SpECinject EP should be used with standard injection equipment having closed containers. The injection pressure should be at least 0.4 N/mm² (4 bar).

Only mix sufficient resin that can be used within the pot life of the material.

Following completion of the injection works, the injection system shall be allowed to cure for 24 hours and shall be left undisturbed for this time.

When using two-component injection machine, mixing takes place in the injection machine.
