ZIPSTRIP
ZipStrip
is a rigid polystyrene "T" shaped strip. The horizontal portion of the "T" is removable while the top portion of the "T" provides stiffness, so the strip can be placed into the wet surface of a concrete slab in a straight line. The bottom portion, or vertical sections, of the "T" resembles the shape of an arrow and has a suitable protruding anchor at the bottom to prevent movement when the top stiffener portion of the "T" is removed. ZipStrip is available in 1", 1-1/2", and 2" vertical depths, and will provide a weakened plane joint in on-grade concrete slabs ranging from 4" to 8" thick.
Architects and Engineers
ZipStrip is the most advanced method of creating weakened plane joints in on-grade concrete slabs. ZipStrip creates an early line of weakness in a concrete floor which insures against surface random cracking. Below the surface, key line cracking takes place around the aggregate which forms a natural locking of both sides of the ZipStrip.
Contractors
ZipStrip is the inexpensive alternative to saw cutting when plane joints are required in on-grade concrete slabs. Concrete surfaces can be finished smooth over the top of the ZipStrip or control joint lines can be tool edged using a preferred radius on slab surface.
