Electrical contractors find it easier to form ductbanks with STAY-FORM® than with plywood or conventional forming systems. The learning curve to train personnel how to install STAY-FORM® is quick, and the labor savings are significant due to the fact that form stripping is not necessary.
Attaching STAY-FORM® to rebar supports is easily accomplished with tie wire.
Attaching a 2×4 (from rebar to rebar) across the top of the ductbank prevents the formwork from spreading during the pour.
Visual inspection of the concrete consolidation is also an advantage when using STAY-FORM® in order to avoid honeycombing.
