Kemko® 050 Slump IR

Injection Resin – Slump Pumping, Structural Epoxy Adhesive for Pressure Injection


Kemko® 050, Slump IR is a two-component, low viscosity, structural epoxy adhesive specifically designed for pressure injection grouting using KIP™(KEMKO® Injection Process) System automatic meter, mix, and dispense application equipment. It is designed for concrete substrate on-grade and vertical concrete substrates where sealing of the opposite side (for containment of the injection adhesive) is not possible. It has the highest viscosity of all KEMKO® low viscosity structural epoxy adhesives and it has a short working time to allow it to gel quickly when mixed and injected. “Slump Pumping” is a phrase coined by the founders of ChemCo Systems which means that the injection resin gels, cures quickly, and leaves residual injection resin on the sides of the crack when some of the injection resin drains out of the unsealed backside. The residual injection resin on the walls of the cracks means the crack will be narrower when reinjected. Slump pumping occurs when the crack is reinjected more than once, eventually filling the crack as residual injection resin builds. Primary uses include the repair of cracks and delaminations in concrete, masonry, stone, and wood. KEMKO® 050 bonds to dry and damp substrates. It contains no VOC’s (volatile organic compounds).

  • Meets - ICRI Guide for Verifying Field Performance of Epoxy Injection of Concrete Cracks


Kemko® 050 Slump IR cures to a tough, resilient polymer and has excellent load transfer capability. Exceptional substrate wetting ensures penetration and filling of fine fissures and tributary cracks as narrow as 10 mils (0.25 mm) in width. KEMKO® 050 is an economical structural epoxy adhesive designed for use when the backside of a crack cannot be sealed. Its physical properties are sufficient for most general repairs. It has a convenient 2:1 (by vol.) mixing ratio and employs special colorants for contrasting component color.
