The invention relates to a bag used for the placement of concrete or grout, either hand placed or pump filled, in and around watercourses. The bags are impermeable and contained in nature, made of biodegradable, degradable or water soluble polymer film, typically made from renewable starch based polymers or water soluble polymers. The bags offer a means of easily and simply placing concrete or grout, safely, cleanly and without risk of contamination to the watercourse or environment from cement leakage, being impermeable in nature, whilst allowing the polymer film to safely degrade, dissolve or disintegrate, in the environment, without the risk of unsightly or environmentally detrimental polythene waste being placed in the watercourse.
