When forming below grade structures like a pile cap, STAY-FORM® can save a considerable amount of time and labor. You have no labor for stripping forms. If rebar or metal is used for bracing, it stays in place. (Wood bracing has to be removed.) Some contractors backfill around the STAY-FORM® prior to the pour therefore they minimize bracing and prevent a blowout of the form.
Contractors can cut the V ribs in order to bend the sheets to any shape.
During the concrete pour any water in the form will run out of the STAY-FORM® as it is displaced by the concrete (no pumping it out).
Concrete finish is not a concern since backfill or a slab-on-grade concrete pour is a typical design with a pile cap foundation.
