MasterFlow 788

Non-shrink, Cementitious Grout with High Washout Resistance for Underwater Applications

How Does MasterFlow 788 Work?

MasterFlow 788 is a ready-to-use, cementitious grout which, on mixing with the specified quantity of water, provides a flowable grout with high resistance to cement washout when placed underwater, with high early and final strength characteristics. The grout undergoes controlled expansion in the plastic state.

MasterFlow 788 is recommended for repairing structures underwater and in tidal zones by grouting. The grout is suitable for use under both stationary and moving waters. Applications include the repair of:

• Bridge piers

• Concrete piles

• Jetty pillars

• Harbour walls

What Are the Unique Features of MasterFlow 788?

MasterFlow 788 has no significant cement washout underwater and gains full strength even underwater.

What Are the Benefits of MasterFlow 788?

• Shrinkage compensated – continues to retain filled volume

• Free-flowing – flows easily even in gaps as narrow as 20 mm, to facilitate complete filling of voids

• Pre-packed – no batching or blending errors, consistency in performance from batch to batch

• Dense microstructure – resists water ingress, protects steel

• High early and final strengths – early load transfer and rapid installation

• High bond strength – primer not required to facilitate good bond
