Abojet Cartridges

For dry or damp surfaces.

ABOJET® CRACK-INJECTION SYSTEM

The Abatron Abojet crack injection system is a proven method to restore monolithic integrity to a cracked structural element by injecting a structural adhesive epoxy compound (Abojet) into the crack to fill and "weld" it back together. Since Abojet bonds permanently and is stronger than concrete, the "welded" wall can be stronger than the original.

Uses: The Abojet series of resins is best known in the restoration of load-bearing walls, such as foundations. Its advantages are also obvious in restoring retaining walls, abutments, swimming pools, marine structures, dams, decks, silos, vaults, bridge piers, columns, domes, concrete pipes, tanks, elevators, sculptures, garages, structural and decorative components, and machinery and equipment supports. Although concrete is the material that is repaired in most cases, most rigid materials such as masonry, marble, stone, wood, ceramics, metals, stucco, and gypsum can be restored with it just as well.

Features and Benefits: Where structural requirements cannot be compromised, the Abojet system is often the only dependable and cost-effective alternative to demolition. Crack-injection with the Abojet resins has also gained prominence in sealing foundations and other under-grade walls against water seepage.

The Abojet Crack Injection Process: An Abojet resin system consists of two solventless (100% solids,without volatiles) liquids packaged separately: resin (part A) and hardener (part B). When needed, A and B are mixed and the resulting blend is then injected into the crack or cavity. A reaction starts when A and B are mixed. The blend will harden within minutes or hours depending on the Abojet chosen. Before hardening the Abojet blend remains sufficiently fluid to be injected. The hardened system is dimensionally stable and virtually shrink-free. (Meets ASTM C881)

Abojet 8702-3: Recommended for wider cracks [>.05" (>1cm)]. Higher viscosity (<60 poises). Ratio A/B: 5/1.

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.
