Block Jointing Mortar

Mega Crete Block Jointing Mortar is a superior water resistant cement based mortar specially formulated for joining blocks.

This mortar is specially designed and manufactured under stringent quality controls to give superior adhesive strength, higher durability and a strong bond between the blocks.

This unique combination enables this mortar to be thinner, compact and versatile.

It also ensures higher bond strength and durability at only 3 mm thickness compare to the conventional mortar at 12-15 mm replacing the conventional cement and sand mix mortar completely.

Details

Excellent bonding to the blocks/bricks
