Underwater bagwork is the handbook placement by divers of woven fabric baggage that contains dry combine, followed by piercing the baggage with steel rebar pins to tie the baggage with each other soon after each and every two or a few levels, and make a route for hydration to induce curing, which might commonly take about 6 to 12 hrs for First hardening and comprehensive hardening by the following day.
