The SL-450 with top section of frame extending parallel to the slope allows the finishing of variable slope lengths. Double-line Spanit® with cleats matches slope profile to allow laborers to finish longitudinal joints and final surface finishing.

The SL-450 has the ability to finish concrete on slopes or a flat slab. This project which included a flat slab with a slight slope was in Birmingham, Alabama.

This GOMACO SL-450 utilized an optional trimming undercarriage to produce accurate subgrade before it is used to finish the concrete lining. This attachment is used for fine grade trimming of lightly compacted soil.

This operation shows canal finishing in a different sequence, with the contractor finishing the left slope right, right slope next and then the bottom.

The Vib-O-Pac vibrating attachment is used on the SL-450 to ensure that the slope surface is sealed when encountering low slump concrete projects.
