CLI Crack Fill (CF 33)



CLI Crack Fill (CF 33) is fast setting, hydraulic cement product formulated to stop leaks in concrete andmasonry surfaces. It is particularly effective for stopping the flow of running water. CLI Crack Fill (CF 33) is ready to use and requires only the addition of water before plugging and sealing cracks.

• Plugs wet cracks in concrete and masonry surfaces to seal out water.
• Stops water seepage at floor and wall junctions.
• Stops running water, reducing damage.
• Expands as it sets for a water tight repair.


• Basement repairs
• Manhole repairs
• Concrete pipe and bell repairs
• Anchoring bolts and hand rail setting


• Ensure that the concrete is clean and rough. Remove all oil, dirt, debris, paint and unsound concrete.
• Ensure that the concrete is clean and rough. Remove all oil, dirt, debris, paint and unsound concrete.
• Use vacuum cleaner or pressure washing to ensure thorough cleaning and removal of all residue.
• CLI Crack Fill (CF 33) does not requires any special bonding procedures.
• Ensure the temperature ranges between 16 OC – 32 0C.
• Add CLI Crack Fill (CF 33) in appropriate amount of water for the batch size.
• Mix with a drill and “jiffy” mixer for about a minute.
• Place the mix immediately on the leaking concrete / masonry surface.
• In case of cracks, widen out and clean cracks to at least 15 mm x 15 mm deep, apply CLI Crack Fill (CF 33) to plug the prepared crack with a pointing trowel and slick off the surface. Prepare a cove at the junction. If more time is desired when preparing the cove, mix the CLI Crack Fill (CF 33) with ice water.
• In case of running water, Dam up running water. Prepare all cracks properly and, if possible, relieve excess hydrostatic pressure by drilling a relief hole or by chiseling out the crack at its very lowest point. Mix an adequate quantity of CLI Crack Fill (CF 33). After mixing, immediately place the plug of CLI Crack Fill (CF 33) in your hand and hold it until it suddenly begins to get warm. This will take 2 –3 minutes from the start of mixing. At this point, speedin working is essential. Force the CLI Crack Fill (CF 33) plug into the hole or crack which is to besealed off. Start filling cracks or holes at the top. To close the final opening and seal off a stream of water, make sure the CLI Crack Fill (CF 33) plug is starting to warm up. At that moment force into the hole and exert pressure either with your hand or trowel for a full 5 minutes or longer to assure setting of the plug. In some cases where thewater is extremely cool, it mat be necessary to hold the plug in place for a little longer.
• In case of Bolt and Hand Rail Anchoring, use a star drill to make a hole approximately 1 – ½”(38 mm) larger than the anchor. Mix enough CLI Crack Fill (CF 33) to fill the area and pour and tamp it into place around the anchor.
• Finish CLI Crack Fill (CF 33) to the desired texture to match the surrounding concrete. Do not add additional water to the surface during the finishing operation. Use CLI Cem AWP as final waterproofing coating for additional protection against water seepage and to improve the appearance and uniformity of the repair area.
• CLI Crack Fill (CF 33) requires no special curing procedures.
