The carbon fiber sew can be utilized on concrete pieces, poured wall surfaces and pool decks.
Stitching techniques can be carried out either by cross-stitching or port stitching. With cross-stitching, openings are pierced vertical to the longitudinal splits or joints. Carbon fiber strips are after that placed into the slots and epoxy is used. The strips are after that bound and backfilled.
An even more modern-day and structured method is slot-stitching. As opposed to boring holes, a port cutting machine or walk-behind saw is used to cut ports with sizes no smaller sized than 25 inches. The slots are loaded with deformed bars, backfilled and healed. This technique is most frequently utilized for repairing longitudinal splits that create piece splitting up.
