Superpatch
Superpatch mortar is supplied as a ready to use dry powder requiring only the addition of water to produce a high strength mortar with non shrink property. The material is a mixture of specially processed cement and carefully graded fine aggregate. Additives impart controlled expansion characteristics and reduce water necessary to produce cohesive mortar mix. The very low water/powder ratio ( 0.14)ensures high early and ultimate strengths.
For repairing thick sections of more than 25mm depth it is necessary to use well graded aggregates ( machine crushed,washed and cleaned) in the size range of 3mm to 10mm.Quantity of aggregates should not exceed 1 part of graded aggregate to 1 part of Superpatch by weight in which case the water/powder ratio will need to be increased to 0.18.
