300ml x 300ml Side by Side Cartridge
240 unit shipment Leak-Proof CUT is low-toxicity, two component 100% solids, polyurethane grout. It will displace and stop flowing water, forming a tough rigid foam firmly bonded to the concrete surface. CUT refers to the products’ ability to quickly “cut” off the flow of water through leaking cracks and joints. This product will also expand to fill voids. See http://www.leakproofonline.com to see the generally equivalent competitor products chart. Leak-Proof CUT
Rigid Foam Polyurethane Grout Uses Leak-Proof CUT can be used to stop water under a hydrostatic head and provide a resilient tough and rigid closed cell polyurethane grout. Cracks in tanks, tunnels, pipes, basements, pools, subways or any structure where water intrusion must be stopped, are capable of repair with Leak-Proof CUT. Can also be used for under-slab grouting projects. High Pressure Procedure (for high water flows) Leak-Proof CUT is supplied in a simple 1:1 ratio unit. It can be dispensed through a 1:1 injection pump or premixed and dispensed through a high-pressure pump or grease gun. Low Pressure Procedure (for low water flow)
Leak-Proof CUT can be supplied in side by side cartridges and is easily dispensed with a manual gun through a 1/4" mix tube. Leak-Proof Injection Ports are used for this procedure. Can also be delivered through a standard grease gun with a flexible whip line to the 3/8" Plastic Hammer-In Packers.

When displacing water the foam development is rapid. Leak-Proof CUT will continue to increase adhesion to the concrete for several hours after grouting. Surface Preparation NOTE: Low Pressure Injection - Use Leak-Proof Ports and fit the fat end into 1/2" holes drilled straight into the crack about 1/3 to 2/3 the depth of the crack. High Pressure Injection - Use Leak-Proof HD Packers (3/8's Plastic Hammer-In Ports) in 3/8" holes. Drill the holes at a 45o angle to intersect the crack approximately 4" below the concrete surface for a 8 inch thick wall. These holes should be drilled alternately on opposite sides of the crack allowing an 8" distance between them. This should ensure intersection of the crack. Alternatively, the holes can be drilled straight into the crack to a depth 2/3 the thickness of the wall, spaced every 3 inches for very tight cracks. (This method allows for higher injection pressures without damage to the concrete through blowouts.) Coat the packer or port with the grout prior to insertion into the cleanly water flushed drill hole for a superior seal. After fitting injection ports or packers, the drill holes should be flushed out using water delivered through a 1/4" hose from a pressure pot (low pressure) or a high-pressure pump or grease gun (high pressure). Be careful to check that each of the holes intersects the crack and a path is available for subsequent injection. Where no travel is evident then additional holes should be drilled to provide the necessary access to the crack. Mixing and Application The side by side cartridge or two component pump is the preferred equipment for grouting with LEAK-PROOF CUT. However, if a one component method is being adopted then LEAK-PROOF CUT should be fully mixed by pouring the contents of "B" into "A" and mixing with a low speed power mixer (200-300 rpm) until an even and smooth consistency is developed. Scrape the sides and bottom of the mix container to ensure a complete mix is obtained. An ACCELERATOR is available for this product (Leak-Proof 2C-ACCELERATOR). You can also special order cartridges with the Leak-Proof 2C-ACCELERATOR included. The accelerator can double the speed of the grout reaction without affecting pot life. It is advisable to mix just a part of the unit initially - 1 litre would be appropriate - to determine rate of travel of the resin and to confirm how much material can be used well within the pot life. Injection of the mixed LEAK-PROOF CUT is then carried out, commencing at the lowest injection point. As the LEAK-PROOF CUT moves into the crack, water is displaced ahead of it. Once all the water is released then LEAK-PROOF CUT will follow the water - when this is observed, injection should move on to the next packer and the same process continued along the crack until it is completed. Excess LEAK-PROOF CUT appearing at the surface of the crack can be easily removed after it has completed foaming, using a sharp knife. Clean Up All equipment must be cleaned immediately after use. Thorough and repeated flushing is required. The equipment lines should then be filled with Leak-Proof PUMP CLEANER to eliminate air/moisture from the lines. Cured material should be mechanically removed. Safety and Toxicity LEAK-PROOF CUT is a MDI based two component polyurethane. Within the generic group of polyurethane polymer technology the MDI based polyurethanes are considered the safest in terms of safety and toxicity. Isocyanates are designated substances and are capable of producing a severe allergic breathing problem in some people. If any Difficulty at all with breathing is experienced the person should immediately vacate the work area. Particular care should be taken to avoid mixing and application in confined areas. Avoid breathing vapours at any time. Two component systems are capable of producing injury to, or destruction of, skin and eye tissues. Precautions must be taken to prevent prolonged or repeated skin contact and it is essential to protect the eyes from splashes. Repeated skin contact can also cause sensitization. Protective clothing, rubber gloves and chemical goggles should be worn when working with these products. A facemask with organic cartridge and a particulate filter is usually adequate. Air supplied mask is suitable for use in confined areas. NOTE: Although reactive chemicals are needed to form LEAK-PROOF CUT the final cured material is a non-toxic foam rubber similar to that used in shoe soles. Storage Store in heated area and on pallets. Do not allow products to freeze. Shelf life in unopened containers is one year. Once opened, then dependent on humidity, shelf life may be reduced to as little as 3 months. Packaging 600 ml side by side cartridges (300 mls "A" / 300 mls "B"). 18.9 litre (5 gal) units, comprised of (9.46 litres(2.5gal) "A" plus 9.46 litres(2.5gal) "B").
Each container is clearly marked with product name, component designation ("A" or "B"), manufacturer's name, batch number and ratio of component mixtures. Containers of "A" and "B" are colour coded the same.
