Bagwork is a straightforward and hassle-free method of underwater concrete placement which would not have to have pumps, plant, or formwork, and which could minimise environmental effects from dispersing cement during the h2o. Prefilled bags can be obtained, which are sealed to prevent premature hydration if saved in appropriate dry situations. The baggage could be biodegradable.[131]
