Concrete repair solution for tunnel applications

2647 Blastcrete Equipment Company says that its novel new Mason Mate system provides an innovative solution for concrete repair and shotcreting in tunnelling applications. The machine features Blastcrete's D3522 hydraulic squeeze pump, a high-shear continuous mixer and an optional 454kg capacity bag lifter. Designed to increase material delivery time, the Mason Mate is said to offer a time saving solution on the jobsite. Rather than mixing material and water off-site, then transporting the blended material with expensive telehandlers to be installed, the Mason Mate can carry out the process on the jobsite and requires just one operator. The unit saves time by being operated on-site and in close proximity to the mason, while also eliminating the need for materials handling.

Featuring a compact design, the Mason Mate can be fitted into the back of a pickup truck and can operate within a 2.44m ceiling. The Mason Mate includes Blastcrete's D3522, hydraulic squeeze pump with variable speed up to 4.7m3/hour and a high-shear continuous mixer for increased speed and shorter mixing time. To relieve pressure build-up clogs and eliminate potential damage to the pump, the Mason Mate's D3522 can be run in both forward and reverse. Hydraulic controls for the pump, mixer, and remixer are located on the operator's control dash. The Mason Mate is designed for easy maintenance and cleaning and is powered by a 21.6kW 1265 Kubota water-cooled diesel as standard. The Mason Mate is also available with either a 26kW Briggs & Stratton petrol engine or 22.6kW electric motor with starter and disconnect.
