Features and benefits
Fills gaps faster and easier
Coremasta’s highly flowable mix gives it more spread than a standard block fill. It prevents segregation and reduces the risk of blocked pumps as well as reducing the need for excessive rodding and vibrating.
Fewer voids
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.
Reach difficult spaces
Coremasta's strong, cohesive and highly flowable mix uses less coarse aggregates than other mixes. This makes it easier to fill hard to access formwork, irregular in-ground structures and shapes and heavily reinforced areas.
