The carbon fiber stitch can be utilized on concrete slabs, put walls and pool decks.
Stitching approaches can be performed either by cross-stitching or slot stitching. With cross-stitching, holes are drilled vertical to the longitudinal cracks or joints. Carbon fiber strips are after that placed into the slots and epoxy is applied. The strips are after that adhered and backfilled.
An even more modern-day and streamlined approach is slot-stitching. Instead of drilling openings, a port cutting maker or walk-behind saw is used to reduce ports with sizes no smaller sized than 25 inches. The ports are filled with warped bars, backfilled and cured. This technique is most frequently utilized for fixing longitudinal splits that create piece splitting up.
