NextStar DIY High-Pressure Concrete Crack Repair Kit

for poured concrete wall crack repairs. High-Pressure Polyurethane Foam Injection for crack repairs between 8-12' of small to hairline cracks that are actively leaking, or not.   Includes blended 100/800 viscosity Injection Foam, High-Pressure Gun, ½ inch packers, etc.


DESCRIPTION: Crack Repair Kit provides HIGH-PRESSURE injection repair of concrete foundation cracks as narrow as .002", and repairs 8-12' of 8" thick poured foundation wall. Polyurethane material is injected up to 4500 psi with this repair method. The 100/800 Polyurethane expands on contact with water or moisture while sealing and expelling out water. This repair method works on actively leaking foundation cracks or all small concrete wall cracks. Ideal kit for those concrete wall cracks that have been previously repaired by hydraulic cement. The blended Polyurethane can expand to 25 times its volume size. For standard cracks with 1/6 inch or larger, we recommend using a low-pressure repair method instead.

 

WHERE TO USE: Poured Concrete Walls Only 

Foundation Cracks that wont stop leaking Foundation cracks that actively leaking water
Foundation Cracks that wont stop leaking Foundation walls where the crack is very small
Narrow loaking cracks in concrete Hairline cracks as narrow as 0.002"
Foundation Cracks that have been repaired before Leaking cracks that have been previously unsuccessfully been repaired

FEATURES AND BENEFITS:

High Pressure Carck Injection Step 5High Pressure Carck Injection Completion step 6

1. Using a hammer drill with a ½ inch masonry bit, start about 3 inches from the bottom, drill holes at a 45° degree angle approximately 5 inches away from the crack so that the hole intersects with the crack. Don’t drill all the way through the wall, about half way through the wall thickness is adequate. Repeat drilling about 6 inches up on the alternate side of the crack of the last hole. If the crack is wider, the holes can be up to 8 inches apart instead.
2. Clean out the holes well as the dust will interfere with the injection penetration. A good method of cleaning is with high pressure air and vacuum or inserting a round wire brush inside the holes.
3. Install each packer. Pound in with provided packer tool so the zerk does not get damaged. Ensure all the rubber of the zerk is inside the hole and tighten until firm.

4. A small crack will be ready to inject at this point, but it is recommended to seal up a wider crack before injection. A good product for this is hydraulic cement. This will keep more product in the wall and keep the job a little cleaner.
5. Mix the Polyurethane with 1 to 2 % catalyst added. The more activator added, the faster it will react with water/moisture It is not that critical but will not react without the activator. Only mix up 1 cup at a time as this is all that is needed to start. Put into the modified grease gun. Only fill to ½ full, maximum.
6. The supplied grease gun has been modified. Open the high-pressure tool and pour in your first mixed batch into the into the tool and reassemble. Face it down and Pump on it until some polyurethane comes out the end. You are ready to inject. The modified grease gun has a valve on the front to let air in as needed
7. Begin injecting at the bottom packer and move to the next packer up the crack on the opposite side when you see the foaming reaction moving close to the next packer. You may also notice the polyurethane pressure pushing off the hydraulic cement. Continue moving up to each packer until you reach the top. At approximately the 6th packer, return to the first packer again and attempt to inject more product. Some of the packers will take more product then other packers.
8. 100/800 Polyurethane can remain active for up to a week after injection. It is best to leave the zerks in place until then, but if needed the tips of the packers can be removed after that and any protruding cured material cleaned up.
9. Ensure to use all the recommended protective gear including the supplied rubber gloves and safety glasses and follow all Manufacturers recommendations for product safety and disposal of material.
10. If you wish to reuse the modified grease gun you must empty out and flush out with xylene solvent then pump some motor oil through to prevent the remaining polyurethane from solidifying in the tool.

USE OF CATALYST The reaction profile is adjusted prior to pumping by the addition of catalyst into the base resin and is affected by temperature and the amount of moisture encountered. At 1.25% (1/2 pint per five gallons) the expansion will start in about 35 seconds and be complete in about 3.5 minutes after encountering water. At 2.5% (1 pint per five gallons) the expansion will start at 25 seconds and be complete at about 2 minutes. These reaction times were determined at 77º F with the addition of 2.5% water.
