ABOJET® CRACK-INJECTION SYSTEM: “Weld” Cracked Structural Elements Back Together
Uses: Restore monolithic integrity to cracked structural elements by injecting an epoxy compound into cracked to fill and “weld” it back together. Seals foundations and below grade walls against water seepage. The Abojet series of resins is most commonly used in the restoration of load-bearing walls such as foundations, retaining walls, abutments, swimming pools, dams, decks, silos, bridge piers, columns, domes, concrete pipes, and tanks.
Features and Benefits: Since Abojet bonds permanently and is stronger than concrete, the “welded” wall can be stronger than the original. It is the perfect solution where structural requirements cannot be compromised and a dependable cost-effective alternative to demolition.
The Abojet Crack Injection Process: The Abojet system consists of a resin and hardener packages in a single cartridge. When the barrier separating them is plunged, they begin to harden. Injected into a crack or cavity, it hardens within minutes or longer depending on temperature. The hardened system is dimensionally stable and virtually shrink-free.
Each 10 fluid ounce cartridge fills 18 cubic inches; nozzles included.

TYPICAL TEST RESULTS
|Abojet® Crack-Injection Method:|
|1.||Clean the Crack.||Ideally, the crack should be clean and dry. Use a water jet, compressed air, or a similar means to render the crack free and accessible. Widen the crack if necessary.|
|2.||Seal the Crack.||For best results, seal the crack along the backside of the wall with a paste like Aboweld 55-1 or Aboweld 8708-2. Then seal also the front side of the crack which will have injection ports. This will contain the Abojet injected from the front side.|
|3.||Install Injection Ports.||Starting at the bottom, insert 2-3 inch long pieces of copper tubing or plastic ports into the sealed crack on the front side of the wall. These should be inserted every 8-12 inches so that each can be used to inject the resin in the crack. Holes can be pre-drilled for inserting the ports. 1/16 inch plastic tubing, like cocktail sticks, can be inserted to hold the ports in place while the Aboweld hardens.|
|4.||Inject Abojet.||Inject the Abojet blend through the lowest port, until the resin starts oozing from the next port above it.|
|5.||Crimp Port Shut.||Crimp the lowest port shut to prevent resin back flow. Inject resin through the port above the crimped port, until the resin starts oozing from the next port above.|
|6.||Continue Process.||Continue injecting resin and crimping the ports until no more resin can be injected. The resin will weld with the surrounding material in a few hours.|
|The sealed surface on the wall can be sanded or otherwise finished. Sufficient structural strength will be reached within 1-4 days, depending on the temperature and bulk. (Warmer environments and thicker sections accelerate hardening.) Horizontal cracks can be filled by simply pouring or troweling. In these cases, ports and caulking guns many not be necessary.|
