Floors on Grade

Bunyan screeds provide powerful control of surface elevation and flatness.  This makes the Bunyan Striker a perfect tool for floors.

The Striker requires the support of formwork, cold slabs, or screed rails. Floor placement often includes slabs greater than the width of the Striker. Split the slab into bays about 25 feet in width with rows of screed chairs which carry 1-1/4” screed pipe. The same screed chair is used on a blind edge, such as a wall of curtain of rebar. Pinheads are placed on top of rebar pins to provide a saddle for 1-1/4” screed pipe, then reused once the pipe slides forward. The Striker cuts slab elevation in reference to the support.
