JCM 116 Repair Sleeve for Concrete Steel Cylinder Pipe The JCM 116 Repair sleeve provides fast, economical and permanent repairs to Concrete Pressure Pipe. Sealing around the damaged area on the steel cylinder, the JCM 116 prevents the line contents from leaking between the concrete/steel cylinder interface, and eliminates further possible damage caused by corrosion. The adjustable, separate gland seals directly on the steel cylinder over the damaged area requiring removal of the mortar coating only in the repair area. Universal grouting horns are located to accommodate re-grouting of the damaged area at any position on the pipe.
