Features & Benefits

• Seals against water: reacts and produces foam resistant to water
• Penetrates deep in fine cracks
• Reacts with water and swells exerting pressure on the substrate sealing against water penetration
• Rapid acting, to produce water stop against moving water under pressure
• Free expansion: 1700% - 2200%
• Does not shrink after curing
• Excellent adhesion to mineral construction materials (such as concrete, cement and brick and metal)
• The reaction speed can be controlled by varying the amount of hardener
• Chemically resistant against water, weak acids, and alkali, mineral oils, fungus and bacteria, ground water, sea water and petroleum products
• Re-injectable with Nitofill UR63 to form permanent seal

Application Notes

• Ensure all contact surfaces are free from oil or grease contamination and suitably prepared to allow Nitokit Surface Sealant to bond
• Injection packers should be inserted into holes drilled at a 45 degree angle to the surface such that they intersect the crack. The distance between each packer is typically between 200 mm and 500 mm depending on the width of crack, depth of crack and degree of water penetration / water pressure
• Before commencing ensure the first packer to be injected has its non-return valve fitted. All other packers should be open
• Pre-weigh required quantities of the resin and hardener. Mix together thoroughly using a drill and paddle, mixing only the amount which can be used within the pot life (see Product Data Sheet)
• Pour the mixed material into the hopper of the injection equipment being used. Connect the outlet hose to the first injection packer and activate the pump
• When resin or foam is seen coming from the next injection packer, deactivate the pump immediately and install a nonreturn valve onto the next packer. Move the injection hose to the next packer and repeat until the entire crack is sealed
• Tools and application equipment should be cleaned immediately after use using a proprietary polyurethane cleaner. Once cured, material can only be removed mechanically. Spillages should be absorbed with sand or sawdust and disposed of in accordance with local regulations
• Clean pump and manual equipment every time there is a stop of more than 15 minutes with a proprietary cleaner, or whenever necessary and at the end of the injection. Flush with an extra 1/4 litre of cleaner

Limitations

• Nitofill WS60 is only suitable for filling static cracks, where a more flexible foam is required consider Nitofill UR63
• At high water pressures on wide cracks the product may not be capable of stopping water
• If no water is present in the structure use lowest hardender level and add 1 part water to 4 part resin to the resin component prior to mixing. It is advisable to use disposable cartridges when adding water to avoid obstructing pump equipment and pipes
