BLINDSIDE WALLS

When a contractor has to form a concrete wall
within a few inches of an existing structure,
Stay-Form is an excellent product. By utilizing
Stay-Form with rebar studs, hook ties,
and a modular form system, a one sided
form can be accomplished. If you do not
have the luxury or room to strip formwork,
Stay-Form is the right product for the job.

• The V ribs run perpendicular to
    the vertical rebar studs which
    gives the Stay-Form the rigidity
    to withstand the concrete pressures.

• Stay-Form can be slit with tin
    snips to accommodate the rebar
    hook tie.

• Concrete pours in 3- to 4-foot
    lifts are preferable with this
    form system.
