The carbon fiber stitch can be utilized on concrete pieces, poured walls and pool decks.
Stitching approaches can be carried out either by cross-stitching or port sewing. With cross-stitching, holes are drilled vertical to the longitudinal cracks or joints. Carbon fiber strips are after that put into the ports and epoxy is used. The strips are then bound and backfilled.
An even more modern and streamlined technique is slot-stitching. As opposed to boring openings, a slot cutting maker or walk-behind saw is utilized to reduce slots with lengths no smaller than 25 inches. The ports are filled with deformed bars, backfilled and cured. This method is most frequently used for fixing longitudinal cracks that trigger piece splitting up.
