​MasterFlow 928HF - High performance, high flow, hydrogen free, non-shrink cementitious grout

MasterFlow 928HF is a ready to use, factory quality controlled, fine grey cementitious powder. It requires only the on-site addition of water to produce a high performance, high flow, non-shrink precision grout with predictable, consistent properties. Special additives ensure hydrogen free expansion in the fresh plastic and the hardened stages to ensure the grout maintains full contact, and efficient load transfer, with the underside of baseplates, or within the void to be filled.  

MasterFlow 928HF is formulated for use at any consistency from fluid to damp-pack, and may be used with confidence for bedding, grouting and precision bearing operations such as:

• Gas or steam turbines

• Generators

• Presses

• Crane rails

• Milling machines

• Precast elements

• Anchor bolts

• Suitable for use in bridge bearing applications

• Form and fill concrete repairs

• It is particularly suited for situations where hydrogen expansion grouts are not allowed 

• Non shrink.

• Adjustable consistency.

• Proven and predictable performance.

• Excellent workability retention even at high ambient temperatures.

• High bond strength to steel and concrete.

• Early strength development.

• Good fatigue and impact resistance.

• Micro silica content enhances strength and durability.

• Impermeable.

• Can be extended by the addition of 5-13 mm clean washed aggregate when large volume void filling is required - MasterEmaco FL 100 aggregate supplied in 20kg bags, subject to approval by Master Builders Solutions​ Construction Chemicals, Technical Services Department.
