CIM is a liquid and does not come in preformed rolls. CIM can be applied using conventional methods (brush, roller, and squeegee) and cures to form a rubber like lining. Because it is liquid applied it will easily conform to irregular shapes and around complex penetrations. CIM unlike sheet goods, will not permanently deform, but stands up better under stress and requires less initial site preparation. CIM, being liquid applied, leaves no seams, leaving no danger for seam failure.
