Fosroc Conbextra EP65 Plus Epoxy Grout Base 11.5L

Code: 40-FC524460-11.5L
U.O.M. - Each
Conbextra EP65 Plus is an epoxy resin based product designed for free-flow grouting of gaps from 10 to 100mm. It is ideal for dynamic/repetitive load applications. Note this Base component must be used in conjunction with part number 40-FC524470-2.5L EP65 Hardener.


Conbextra EP65 Plus is a solvent-free rapid hardening, ultra high strength epoxy grout. It is designed for use as a heavy duty multi purpose grout for engineering applications. Supplied as a two component system consisting of epoxy resin, combined with inert fillers and the hardener, to produce a high viscosity fluid grout.

Conbextra EP65 Plus can be used for grouting under baseplates, crane rails and turbines where heavy dynamic loads are encountered and areas where chemical spillage may occur. Typical applications include reciprocating machinery, heavy crane and transporter rails, high speed turbines, centrifuges, drop forges, anchoring of steel bars, electroplating and chemical plants.


  • Very high compressive, tensile and flexural strengths
  • Resistant to repetitive dynamic loads
  • Fast, convenient installation with high early strength gain
  • Withstands a wide range of chemicals
  • Low creep characteristics under sustained loading
  • Ideal for:

  • Reciprocating machinery
  • Heavy crane and transporter rails
  • High speed turbines
  • Centrifuges
  • Drop forges
  • Anchoring of steel bars
  • Electroplating and chemical plants

    Surface Preparation:

    All surfaces must be free from oil, grease, free standing water or any loosely adherent material. Concrete surfaces should be cut back to a sound base. All dust must be removed and bolt holes or fixing pockets blown clean of any dirt or debris.

    All steel surfaces should be shot blasted free of rust, paint and scale. Formwork should be constructed to be leakproof as Conbextra EP65 Plus is a free flowing grout. Forming materials should be coated with a release agent such as grease or wax material or a plastic coating.


    Pour the entire contents of the hardener pack into the base container. Mix the hardener slowly into the base using a slow speed heavy duty mixer until a uniform mix is obtained. For large pours purpose made grout pumps can be used.


    The mixed grout should be poured steadily from one side only to eliminate the entrapment of air. Continuous grout flow is essential.

    Clean Up:

    Equipment should be cleaned immediately after use with solvent such as Fosroc Solvent 10.


    Shelf life of 12 months from date of manufacture if kept in a dry, cool store in the original packaging.
