1. A concrete curing blanket comprising:
a contact layer for contact with a concrete surface;
a cover layer including a liquid and/or vapor impermeable polymer material for maintaining liquid and/or vapor in the blanket and preventing liquid and/or vapor leakage into the atmosphere;
a storage layer for storing liquid, the storage layer intermediate the contact layer and the cover layer; and,
the contact layer, the storage layer, and the cover layer joined together along a plurality of longitudinally extending seams, the seams dividing the blanket into at least two channels between adjacent ones of the seams, each the at least two channels including a space between the storage layer and the cover layer to maintain vapor from the storage layer;
wherein the seams which join the contact layer, the storage layer and the cover layer, together, proximate to the ends of blanket, operate to prevent liquid and/or vapor leakage from the concrete surface into the atmosphere and maintain saturation of the concrete surface.
