High strength free flowing micro concrete

  • Rapid strength development and high ultimate strength
  • Shrinkage compensated
  • Minimal drying shrinkage

Features and benefits

High strength free flowing micro concrete suitable to repair large volume of concrete repairs at thicknesses from 10mm to 250mm.



POLYBIT® POLYCRETE MC can be used as a pile head re-profiling and general void filling; large volume or area repairs where the use of hand or trowel applied mortars is impractical; it can be applied for large volume repairs in excess of 10 mm. the product can be applied in sections generally up to 250 mm; in repair areas with restricted access or high concentration of reinforcement; due to the plastic nature of the product, it can be used as grout and poured under a head of pressure. Available pack size: 25kg bag.

How to use


Concrete substrate to be repaired should be sound, clean, and uncontaminated. The formwork should be rigid and tight to prevent loss of grout and have properly sealed faces to ensure that no water is absorbed from the repair material. Saw cut the Any rebar that has lost more than 25% of its original diameter should be cut out and replaced. Prime reinforcement with Polyzinc*, zinc rich primer.
Priming is not required, pre-wet substrate and remove any contaminants and standing water before placing the grout.


One bag (25kg) of Polycrete MC requires 2.75 - 3.25L of clean potable water. In hot climates, the use of cold water (< 25°C) is recommended. Mix in a suitable size drum using an approved grout paddle at a slow speed (300/400 rpm) with a heavy-duty drill. Pour required amount of water in the mixing vessel followed by Polycrete MC. Mix for 3 minutes to get a homogeneous and consistent mix. The mixed material should be placed within 30 minutes. It can be poured or pumped in to the repair area to fill the cavity at the required level. No vibration is required. After concrete has initially set, the surface may be finished to the desired texture. Due to the presence of rapid drying polymers, the repaired area shall be cured in accordance with good concrete curing practice. curing shall be done by non degradable type of curing compound or wet hessian cloth. When cured with wet hessian cloth, the area shall be covered immediately with a high density polyethyelene sheet which shall be taped to all edges. 


The material shall be stored in a cool, dry and shaded area. In tropical areas the material shall be stored in an air-conditioned environment. Shelf life up to 12 months in un-opened containers. Exposure to excessive heat and humidity will affect the quality of the product and reduce its shelf life.
