ABSTRACT:
A grout delivery system includes a grout storage hopper connected to a motor-operated pump to pump flowable grout or mortar through a flexible hose into a nozzle structure for application to a work surface. A nozzle handle contains a pushbutton actuator for a pump motor speed control circuit. An operator can observe grout flow from the nozzle while operating the pushbutton to adjust the grout flow rate. The pump motor speed control allows the operator to apply grout at a relatively high rate and with a high degree of accuracy, because the grout flow rate can be increased or decreased, as necessary to fill cracks or crevices of different size.
