N E T SLAB/HORIZONTAL SCREEDS MegaScreed ™ - Plastic Determine the finished elevation of concrete with a laser or string line and position a #4 rebar stake on the subgrade at the strikeoff point. Place the MegaScreed Driver over the rebar and strike with a Dead Blow Hammer until the height marker aligns with the laser or string line. Remove the Driver and place the high strength Yoke over the rebar. The Yoke will maintain the exact position indicated by the height marker. Repeat this procedure as necessary at each screed location. Then set a 1-1/2" ID, 2" OD schedule 40 screed pipe on top of Yokes and you are ready to pour. 100 per package. Pinhead - Metal Several locations can be set at the same time. #4 rebar stakes are driven in line, about 5 feet apart, about floor grade. Each stake is then shot and driven to elevation of 1-13/16" below finished floor grade. Pinheads rest on these stakes and provide a saddle for the temporary screed pipe. A 1-1/4" ID pipe will slide forward with each mixer load, leaving the Pinheads free to remove and reuse. 100 pieces per carton. Zip Strip A simple method of creating a weakened plane in flat concrete surfaces. Creates an early line of weakness in concrete slabs helping prevent random cracking. 500 lf per carton. Application: • The location of the joint should be screeded and floated before installing Zip Strip. • With a straight edge guide, groove out a slot to the desired depth. The depth should be equal to the depth of the Zip Strip and at least a fourth of the thickness of the slab. Groove the slot well to part any aggregate that might block insertion of the Zip Strip. • Press Zip Strip down into the formed groove so that the removable top is level with the surface of the concrete. • Finish by pulling the top section off to leave the joint former firmly embedded in the concrete. • Trowel and finish off concrete.
