1944 Teresa Melocco died on August 21 and was buried (grave 30, section 11) at Rookwood Cemetery.

In October, Melocco Brothers launched its pre-mixed concrete business, Certified Concrete, which set itself apart by guaranteeing the weights and measures of concrete delivered from its batching plant in Wigram Road, Annandale — the first of its kind in Australia. Certified Concrete also introduced to Australia the first contemporary-style concrete mixer based on the Archimedes Screw. Galli designed the mixer and 18 of them were built by Jim Bunyan — all two-and-a-half-cubic-yard inclined axis transit mixers, based on descriptions Galli had heard of American machines. These units, powered by Dodge-4 engines and using Model T Ford gearboxes, were mounted on International KBS.5 and ex-army Chevrolet trucks. The largest pour made by the fleet was 223-and-three-quarter cubic yards at Waddington’s, Granville, one Saturday morning.
