Compressor Finisher |
Compressor finish is a relatively new surface-finish method for pervious using a non-weighted pan machine, developed by Dave Mitchell of Bunyan Industries. Immediately after the roller-screed pass for leveling, the non-weighted pan is floated several times across the surface, and provides a relatively dense yet still pervious surface. Though John Bazella is currently doing trials with a conventional motor-mounted pan mixer, the Bunyan version used an off-machine compressor for power, and the long handled-pan allows the operator to finish without walking on the new surface. The compressor also powers the roller-screed used for initial strike-off.
Pan-Finish |
Pan-finish uses a non-weighted pan method leaves a
fairly closed and level surface, almost resembling a base-course asphalt mix,
and eliminates hand-troweling except for slab edging. Low spots are
easily filled in with additional fresh mix panned in, and high spots are
quickly leveled by the low-rpm pan.
Bean Oil |
Bean Oil is immediately used after
panning, a light coat is applied by sprayer as a moisture stabilizer for
the surface. This is an eco-friendly soybean-based light oil that has
universal uses.
Plastic Cover |
Plastic sheeting is
immediately placed over the concrete and generally left in place for 7
days. The entire process from truck chute to roller-screed to finish,
spray, and cover, is typically only about 15 minutes – a far cry from waiting
for conventional slabs to gel, bleed, finish, etc.
