Micro Concrete

Micro Concrete is a specialized, structural repair mortar or flowable non-shrink grout formulated for high early strength, volume stability, and exceptional load-bearing performance under dynamic stresses. Engineered to withstand harsh temperature gradients, it prevents micro-cracking and is designed to provide reliable support for baseplates, structural connections, and reinstatement works.

Product Overview

Flowable Micro Concrete belongs to the Grout & Micro Concrete family. It is intended for column and beam jacketing, large voids, structural member repairs and precast and infrastructure reinstatement. Final product selection must account for substrate condition, exposure, application method and compatibility with adjoining layers.

Application Guidelines & Installation Method

Step 1: For cementitious grout, clean the substrate, mix to the specified water ratio, place or pour continuously to avoid voids, and cure as specified.

Step 2: For epoxy grout, use a clean, dry substrate, mix components to the specified ratio, place and compact continuously, remove excess and cure.

Step 3: For micro concrete, prepare and dampen the substrate as specified, install formwork where required, mix to the stated water ratio, place and compact continuously, then cure and protect.

Standard Compliance

Conforms to ASTM, BS EN, and local municipality green building regulations. Verified through independent laboratory testing and certified project listings.
