Expansion Joint RepairBack to
Flexane® 94 Liquid
Undersea road support structures required moving onto a submergable barge for placement into the sea. To provide a smooth and level surface on the barge deck, ITW Chockfast was used. Cracking occurred due to the enormous weight of the support structures and the flexing of the barge from rolling seas. Surface cracking and hollow, uneven expansion joints caused extreme difficulty when rolling the support structures onto the barge.
Flexane 94 Liquid was used to fill expansion joints and repair cracked areas on the barge deck because of its extremely high compressive strength and excellent flexibility. Crack and expansion joint areas were roughened and then chemically cleaned using Cleaner Blend 300. Expansion joints were filled or stuffed with a polypropylene backer. This prevented Flexane 94 Liquid from migrating deep into the concrete. FL20 Primer was then applied and allowed to cure or dry for 15 minutes. Flexane 94 Liquid was poured into the expansion joints and cracks, which provided a smooth, flexible, (350% elongation), level surface for the structure to be easily and safely moved .
