Binary Engineering offers products for repairing leaking cracks in concrete bridge walls, decks, tanks, and foundations. Using epoxy and urethane methods are offered using high pressure injection pumps or dual manual injection guns. State of the art urethane grouts and epoxies are available. We specialize in the manufacturing of materials and equipment for all kinds of basement water issues including basement leaks, concrete crack injection, foundation repairs.

The injection packer is a tool for sealing works. It is tightly fixed in the drill hole of the building component and connects the injection device with the building component. Under pressure the sealing material is injected into the damaged building component. Injection packer is suitable for particularly high pressures. It is especially suitable for small cracks or should be used when drilling would cause damage, e.g. for tiles and stones.

The method starts by drilling into the wall every 8 to 10 inches at a 45 degree angle with the goal of intersecting the crack somewhere in the middle of the wall. Alternate sides to insure intersection. A mechanical packer is then placed in the drill whole and wrenched snug. Finally, the drill pump is attached to each packer, starting at the bottom and working up the wall.



Binary Engineering has the capabilities that meet the requirements of large and small customers worldwide.

In order to make injection  packer stronger and more durable, Binary Engineering uses prime quality raw material to manufacturing products. Moreover, our injection packers are all standard-equipped with high-pressure fittings, so that help your work safer and easier.

Offer top quality injection packers at reasonable price to customers are one of our core tenets. If you are interesting in our products, please do not be hesitating. Contact us soon with through phone call and e-mail.

Method of Construction for Injection

1. Crack and leakage condition inspection

Check the process procedure after finding the thickness, width and depth of crack and leakage condition of the structure

2. Drilling Operation

Drill directly into crack section if the thickness of concrete is thinner than 10cm. For the thickness of 10cm~50cm, drill it with 45 degree angle by keeping a distance of 1/5 of concrete thickness. Make sure it penetrates the crack section. If the thickness is over than 50cm, keep the distance of 20cm~30cm and drill it with 45 degree angle until it penetrates crack section. And keep drilling by maintaining the fixed interval. (5 holes per 1 meter. Drill it in zigzags)

3. Packer Installation

Clean the inside of drilled holes with compressor. Make sure that rubber sleeve of packer and cutting line of tightening nut should be put into the inside of concrete surface when installing. Tighten the packer completely by using the T-box. (Packer might be damaged if you tighten it too strongly)

4. Injection Operation

Inject the waterstopping material by using the high pressure device or grease gun. Maintain the initial injection pressure as around 40kg/cm and increase the pressure by each 10kg/cm gradually until the waterstopping material flows out from crack section. Water will come out from the crack section first and then waterstopping foaming agent and then water stopping liquid at last. If the waterstopping material that is not foamed comes from the crack section, then move to next packer for injection.

5. Packer Removing Operation

Remove and break the packer by using vise pliers or hammer as a tool. If there is still a wet section, then inject the water stopping material again.

6. Finishing Operation

Remove the water stopping material that is remained on the crack section. Spreading with the elastic sealing material.

Construction Notes

  1. First, analysis cracks’ width and length,take cores to determine the development of crack depth.
  2. If the surface is not easy dry, you can use torch drying, cracks due to moisture, can be found immediately to improve efficiency.

Crack Repair

  1. Injection should be started in elevation from bottom to top, when the foam materil emerge from the cracks should immediately stop,and start again after a while. In the infusion process, if the material adjacent to the needle position has been filled, you can jump without injection. If found cracks extension in both ends or cracks with cross, should drill holes again, re-grouting.
  2. To fill cracks with polyurethane, should grout again before the material become solid.
