Fosroc Conbextra EP300 DP Epoxy Resin Grout Base 2.7L

Code: 40-FC500547-2.7L
U.O.M. - Each
Low exotherm three part epoxy resin grout suitable for large volume pours. Conbextra EP300 DP is designed to be grouted into gaps from 10mm up to 300mm. Grouting of gap widths below 50mm will take longer to cure due to the low exotherm nature of the grout. Note this product should be used in conjunction with EP300 DP components, part numbers 40-FC500546-20KG Filler and 40-FC500545-860ML Hardener.


Conbextra EP300 DP is designed to be grouted into gaps from 10mm up to 300mm. It is ideal for applications involving heavy dynamic or mobile loads, or where long working time and/or large volume grouting is required. Applications include


  • High compressive, tensile and flexural strengths
  • Resistant to repetitive dynamic loads
  • Fast, convenient installation
  • Withstands a wide range of chemicals
  • Virtually no shrinkage
  • Low creep characteristics under sustained loading
  • Excellent flow properties
  • Can be used installed at high temperatures
  • Wide range of gap thicknesses are possible
  • Ideal for:

  • Reciprocating machinery, testing equipment, heavy crane and transporter rails
  • High speed turbines, centrifuges and drop forges, pile head waterproofing
  • Conditions where chemical spillage may be encountered
  • Steelworks, refineries, electroplating works 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. Bolt holes and fixing pockets should be filled prior to the main grouting pour in order to reduce the possibility of air entrapment under the base plate.

    All steel surfaces should be shot blasted free of rust, paint and flaky mill scale.

    Formwork should be constructed to be leakproof as Conbextra EP300 DP is a free flowing grout. Loss of grout once the material is placed, but not hardened, will result in incomplete filling of the gap. Forming materials should be coated with a release agent such as grease or wax material or a plastic coating.


    Pour all the contents of the hardener pack into the base container. Mix the hardener slowly into the base. Once the base and hardener have been mixed slowly add the filler component and continue to mix for a further 2 minutes until the filler has been wetted out and a uniform colour is achieved. For large pours a purpose made grout pump can be used such as a diaphragm pump.


    Continuous grout flow is essential. Sufficient grout must be available prior to starting and the time taken to pour a batch must be regulated to the time taken to prepare the next one. The mixed grout should be poured only from one side of the void to eliminate the entrapment of air.


    EP300 DP Base and Hardener components have a shelf life of 5 years and the Filler has 12 months if kept in dry conditions and out of direct sunlight.


    Makes an 11.4 litre 3 component pack. Combine 2.7L Base with 20kg Filler and 860ml Hardener.
