Technical Information
Product Description

EPOGROUT GP FLEX is a high strength, flexible material three component fluid urethane epoxy grout consisting of base (A), hardener (B) and graded filler (C). Specially formulated to be used as a pile head treatment. When applied to top of the pile head treatment the product provides a highly bonded waterproofing barrier to the pile head which prevents water seepage from ground to the pile caps through the piles.

  • Excellent performance under dynamic or mobile loads
  • High early strength gain
  • Non-shrinking with high adhesion to contact surfaces
  • High compressive, tensile and flexural strengths
  • Flexible
  • Chemical resistant
  • Durable
  • Low creep characteristics under strained loading
  • Excellent adhesion to steel and concrete
  • Excellent fatigue resistance
  • High resistance to dynamic loads, thermal effects and chemical attacks
  • Primer not required
  • Compatible with torch applied and self adhesive membranes.

Application Information
Instructions for use

Surface Preparation

Concrete must be cured for a minimum of 21 days. All surfaces must be clean, sound, uncontaminated, free from oil, grease, water, paints and dust. Unsound concrete must be removed. Compressive strength of the concrete should not be less than 25 N/mm2

Concrete surface must be totally dry when the mixed product is poured as wet surface might cause de-bonding between concrete and the grout.

Steel surfaces should be free of rust. Sand blasting or grinding is recommended.

Formwork must be well braced, leak proof, strong and well fixed as EPOGROUT GP FLEX product is free flowing grout.

Anchor bolt holes should be clean of all dust, dirt and should be dry.



EPOGROUT GP FLEX is supplied in a pre-measured packing. Partial mixing should not be allowed under any condition.

Start mixing by pouring hardener B into base A, the two components must be well mixed to ensure proper chemical reaction. Use a slow speed drill fitted with suitable paddle to mix the product at low number of turns (200 – 300 rpm).

Mix for few minutes till a homogeneous mixture is obtained, then add component C (filler/aggregate) and mix for 2 – 3 minutes until you get homogenous mixture.


Start pouring the grout from one side to eliminate air entrapment, the placement of the grout must be continuous. EPOGROUT GP FLEX should be used immediately after mixing the components and during the working time of the mix.


All used tools should be cleaned with SOLVENTE 10 before the product cures. Hardened material should be removed mechanically.


  • Do not apply EPOGROUT GP FLEX if the temperature is less than 5⁰C.
  • Partial mixing of the product components should not be allowed under any conditions
  • Extra care should be taken when applying at high temperature as pot life of the mixed product will shorten automatically.
  • It is recommended to shade the working area while mixing and placing EPOGROUT GP FLEX.
  • Do not expose to running water until cured.
