Features and Benefits

CoreMasta’s highly flowable mix gives it more spread than a standard block fill like CoreCrete. It prevents segregation, and reduces the risk of blocked pumps or the need for excessive rodding and vibrating.

CoreMasta is specially designed at a higher nominal slump to avoid excess water addition on site. It is self-levelling, fills voids better, needs less compacting, and doesn't flow through cracks and brickwork.

CoreMasta’s strong, cohesive and highly flowable mix uses less coarse aggregates than CoreCrete. This makes it easier to fill hard to access formwork, irregular in-ground structures and shapes, and heavily reinforced areas.
