Abstract (en)
A bag (1) particularly for receiving a pumped settable liquid which when set forms a solid block. The bag is substantially air-tight and is filled at a rate which pressurises the air trapped in the bag so as to cause the bag to expand up to its full size. Over-pressurisation is prevented by a relief valve in the bag formed by a seam which is weaker than the other seams.
