Surface Adhesive Packers
ADHESIVE SURFACE PACKERS:
also, called as ‘surface PACKER PORTS’ used for epoxy injection at low injection pressures. They are glued to the concrete surface usigan epoxy adhesive. The port inlet is fitted with non-return nipples that prevent the epoxy to flow back. This type of packer is normally used on dry condition for hairline cracks to wider cracks in dry conditions.
Application Instructions:(Adhesive Packers):
– Identify and mark the length of the crack area to be injected, then open the crack by grinder.
– Clean the substrate with wire brush at a distance of 25mm on both sides of the crack. Wire brush is recommended
because grinders often leave dust in the crack.
-Measure the width of crack in order to determine the correct product to be injected.
-Once crack is exposed, clean and dry; you may adhere to adhesive packers.
-Adhesive packers or surface ports are recommended for wide or surface cracks and clear in nature cracks; and when the substrate thickness is small and will be dependent on a slow operating injecting pressures.
– Adhesive packers are typically placed at 20mm spacing, with increase spacing up to 50mm on wider cracks.
-The packers are secured to the crack with epoxy paste/sealer.
-Prepare and mix the two components of epoxy paste1:1 ratio until achieving a uniform homogeneous gray compound.
-Using a spatula, apply the mixed epoxy paste across the surface of the crack on a band of 50mm. Be sure not to cover the bottom opening of the packer with paste as this will prohibit the flow of resin into the crack. -Once the epoxy paste is fully cured, you are ready to connect the injection pump.
-On a clean container, mix the two components of epoxy resin with a slow speed electric drill fitted with mixing paddle until a homogeneous mixture is achieved.
– Pour the mixture of epoxy resin onto the tank of the Injection Pump ready to inject.
-On initial injection process, pump out the few drops of material on a separate container so as to make sure material is oozing from the nozzle properly.
-Start injecting at the lowest packer of the crack length, while leaving the above packer open.
-Connect the injection pump onto the adhesive packer and commence injection process.
-Vertical cracks are typically injected from the bottom up, while horizontal crack injections are commonly initiated at the point of widest crack width.
-Continue to pump the epoxy resin into the adhesive packer until you see material exiting from the adjacent packer. At this time, closed the adjacent packer with nipple and fix the injection pump and continue the injection process until the length of the crack is fully injected.
-After all the packers/ports are injected, it is recommended to allow adequate time for the epoxy resin to completely cure.
-Adhesive packers/ports can be removed by grinding.
Product Description Adoration Injection Packers are filling valves or ports and connection pieces between the injection equipment and the structure. One way valves (i.e. Zerk or button head fittings), are located on the top of the injection packer and connect to the injection equipment.
Uses Adoratoin Injection Packers serve as filling valves or ports and connection pieces between the injection equipment and the structure when sealing structures or repairing cracks by injection. They can be used for the injection of various mat
Characteristics / Advantages A full range of Adoration Injection Packers are available (Mechanical and Surface Packers) Designed to accommodate and withstand the relevant pressures and flow rates without leaking or ”jumping-off”.
