Surface Adhesive Packers

Surface Adhesive Packers (Surface Packer Ports) are used for epoxy injection at low injection pressures. Glued to the concrete surface using epoxy adhesive, they feature non-return nipples to prevent resin flow-back. Ideal for hairline to wider cracks in dry conditions.

Key Features

Glued to concrete surface — no drilling required
Non-return nipples prevent epoxy flow-back
Ideal for low injection pressures
Suitable for hairline to wider cracks in dry conditions
Full range of surface packers available
Designed to withstand relevant pressures without leaking or jumping off
Serve as filling valves between injection equipment and structure

Product Description

Surface Adhesive Packers, also called Surface Packer Ports, are used for epoxy injection at low injection pressures. They are glued to the concrete surface using an epoxy adhesive. The port inlet is fitted with non-return nipples that prevent the epoxy from flowing back.

This type of packer is normally used in dry conditions for hairline cracks to wider cracks. They serve as filling valves or ports and connection pieces between the injection equipment and the structure.

Characteristics and Advantages

Full range of surface packers available
Designed to accommodate and withstand the relevant pressures and flow rates without leaking or “jumping off”
Non-return valve prevents resin flow-back
No drilling required — surface-mounted application

Application Instructions

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 crack width in order to determine the correct product to be injected.
Adhere surface packers once crack is exposed, clean, and dry. Surface packers are recommended for wide or surface cracks that are clear in nature, and when the substrate thickness is small.
Place packers at typically 20mm spacing, with increased spacing up to 50mm on wider cracks.
Secure packers to the crack with epoxy paste/sealer. Prepare and mix the two components of epoxy paste at 1:1 ratio until achieving a uniform homogeneous gray compound.
Apply mixed epoxy paste across the surface of the crack on a band of 50mm using a spatula. Be sure not to cover the bottom opening of the packer with paste as this will prohibit the flow of resin into the crack.
Wait for full cure of epoxy paste before connecting the injection pump.
Mix epoxy resin — 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.
Begin injection — start injecting at the lowest packer of the crack length, while leaving the above packer open. Vertical cracks are typically injected from the bottom up, while horizontal crack injections are commonly initiated at the point of widest crack width.
Continue pumping the epoxy resin into the adhesive packer until material exits from the adjacent packer. At this time, close the adjacent packer with nipple and continue the injection process until the length of the crack is fully injected.
Allow curing — after all the packers/ports are injected, allow adequate time for the epoxy resin to completely cure.
Remove packers — adhesive packers/ports can be removed by grinding.
