The Traker is a manually operated tool for installing contraction joints in concrete slabs-on-ground. When pushed across a slab, the tool folds a strip of plastic tape and embeds it into fresh concrete. The tape remains in the slab to create an effective contraction joint. The advantages of using the Traker are cost and speed. The Traker installs joints at 75% less cost, and four times faster than sawcut joints. The primary market for the Traker is residential slabs-on-ground, where contraction joints are hidden by floor coverings. Joints formed by the Traker appear as narrow joint-cracks in the slab.
