ZipStrip is inserted in the concrete when the concrete
is still wet, preferably after screeding and tamping. A straight
vertical line of weakness is formed where ZipStrip was inserted. The top
portion of the ZipStrip is removed leaving the vertical portion in the
concrete to form a
weakness in the surface of the slab to the ground. The new joint can be
tooled with a radiused edger or the
surface of the slab
can be finished over the top of the joint. As the slab shrinks during
the normal curing process a slight straight line separation on the
surface of the slab will appear where ZipStrip was inserted.
When
panels are poured on top of the floors in tilt up construction where
ZipStrip was used, the probability of telegraphed lines
on the exterior
panels will be minimal eliminating the need for costly repairs.
