FORMING SERVICE VOIDS IN CONCRETE

THE FOLLOWING WAYS TO FORM SERVICE VOIDS IN CONCRETE ARE REVIEWED: STEEL PIPE, PAPER TUBES, WOODEN PLUGS AND POLYETHYLENE SLEEVING. PLASTIC SLEEVES ARE MADE FROM LINEAR POLYETHYLENE AND ARE AS RIGID AS SHEET STEEL. PLASTIC WILL NOT RUST NOR DISCOLOR CONCRETE, AND IS AN IDEAL INSULATOR FOR COOPER PIPE AND ELECTRICAL CONDUIT. PLASTIC ALSO MAKES A NON-ABRASIVE INSULATOR FOR HIGH SILICONE IRON PIPE AND FOR GLASS PIPE WHICH IS NOW BEING USED FOR CORROSIVE WASTE. SLEEVING OFTEN PLAYS A DUAL ROLE. ITS PRIME FUNCTION IS TO ALLOW ACCESS TO THE FLOOR ABOVE AND, SECONDLY, IT ACTS AS A MOISTURE BARRIER.
