Installation Recommendations:
The AMICO rule of thumb is to “brace STAYFORM® like you would a piece of plywood.” The use of rebar, strongbacks, walers, kickers, etc. (location, size and spacing) is similar to that for conventional forming methods per ACI 347, Guide to Formwork for Concrete.
- The STAYFORM® ribs face into the concrete pour
- 4”-8” minimum lap between running STAYFORM® sheets
- 2-rib minimum lap between stacked STAYFORM® sheets
- Attach STAYFORM® to bracing with wire, staples, roofing nails or other mechanical fasteners.
- Tie wire around rib and bracing is recommended.
- Bracing where sheets lap is also recommended.
- Cut STAYFORM® sheets with a hand-held grinder, cutoff saw, abrasive blade or metal snips.
