VELOSIT® NG 513
Underwater Non-Shrink Grout For 12 - 120 mm
Product Description
VELOSIT NG 513 is a pumpable cementitious underwater grout for concrete substrates. It is used to fill large voids or restoration of concrete elements like piles or secant pile walls. VELOSIT NG 513 creates an extremely well bonded, high strength connection between concrete and concrete or concrete and steel. VELOSIT NG 513 is the result of many years in the field testing and research. VELOSIT NG 513 is a double shrinkage compensated cementitious underwater grout with quick strength development.
