Portable, Mobile Formwork for Power Screeds
Adjustable, light-weight, rapidly installed and removed, temporary form for accurately gauging the strike-off of concrete slabs, pavements, and overlays (down to 1½” thickness). Provides rigid, at-grade reference for all types of manual straightedges and light “vibra-screeds” (e.g. Vibra-Strike® units). Supported at ends either on previously struck concrete and sub-grade by float and manual screw jack, or on sub-grade alone by two manual screw jacks. Optional sand / poly pads can be installed on jacklegs. Can be configured to produce constant thickness slabs and overlays (i.e. to follow the sub-grade) by fixing the jack elevation(s), or to produce planar slabs and overlays by readjusting the jack(s) to laser plane as work proceeds.
