Estogrout FP70

High Strength, High Flow Dual Stage Shrinkage Compensated Grout

Download Data Sheet



Estogrout FP 70 is a special formulated grout, which impart controlled expansion in both the plastic and hardened states.

Estogrout FP 70 is a pumpable non-shrink, self-levelling, cementitious grouting mortar with extended working time to suit local ambient temperature. It is supplied as a ready to use dry powder.

The addition of a controlled amount of clean water produces a free-flowing precision grout for gap thickness up to 125mm. In addition, the low water requirement ensures high early strength and long-term durability. The filler grading minimizes segregation and bleeding over a wide range of application consistencies.

Estogrout FP 70 has been tested by SIRIM BHD in accordance to ASTM C942:1999, on Compressive Strength Test and complied with the specification in this data sheet.


Estogrout FP 70 is suitable for repairs to concrete structures and the following grouting works with clearance of 5mm or more:-

  • Machine foundations
  • Concrete anchors
  • Rail beds / Bridge bearings
  • Cavities / Gaps / Recesses
  • Honeycombs


  • Easy to mix and apply
  • Two step expansion in both the plastic and hardened states
  • High Early Strength enables rapid installation and early operation of plant
  • Excellent flow and flow retention
  • Non-toxic and non-corrosive
  • Chloride and hydrogen free gaseous expansion
  • Impact and vibration resistant
  • Suitable for pumping or pouring over a large range of application consistencies and temperatures.

Application Instructions

Surface Preparation

Concrete surfaces should be clean, sound and free from oil, grease, laitance and loosely adhering particles.

Metal surfaces (iron and steel) should be free from scale, rust, oil and grease.

All absorbent surfaces must be well saturated with clean water, but be free of any surface water or puddles prior to the application of Estogrout FP 70

Form a leak proof formwork as Estogrout FP 70 is a free flowing grout.

The gap width between the perimeter formwork and the plate edge should not exceed 150mm on the pouring side and 50mm on the opposite side. There should be no gap at the flank sides.


The quantity of clean water required to add to a 25kg bag grout to achieve the desired consistency is

Consistency Water Yield
Trowelable 4.0 litres 13.15 litres
Flowable 4.5 litres 13.25 litres
Fluid 5.0 litres 13.80 litres

Refer to mixing ratio guide for water: grout ratio mix for 2 to 3 minutes with a slow speed drill (max. 500 RPM)


After mixing, stir lightly with a spatula for a few seconds to release any entrapped air. The grout is then poured immediately into the prepared formwork.

When carrying out base plate grouting, maintain suficient pressure head for uninterrupted mortar flow. The prepared formwork must be firmly in place and kept watertight.

When placing grout over a large area, it is important to maintain a continuous flow throughout. Organize proper work sequence to ensure uninterrupted flow. In large areas, pump Estogrout FP 70 with a heavy-duty diaphragm pumps. Screw feed and piston pumps may be used.

For sections thicker than 50mm, it is necessary to fill the Estogrout FP 70 with graded 10mm silt free aggregates to minimize temperature rise generated during the curing stage. The quantity of aggregates should not exceed 1 part aggregates to 1 part Estogrout FP 70 by weight. For such mixes, a conventional concrete mixer and pump may be used. To further ensure that air entrapped during mixing allowed to fully escaping, it may be necessary to make breather holes. Use steel rods or chains to assist the flow of grout where necessary.


On completion of the grouting operation, all exposed areas that are not to be cut back should be thoroughly cured. Apply suitable curing membrane such as Estocure WB or continuous application of water after initial set for curing purpose.
