Surface injection packer have small hole at the base, it is good for adhesive with glue. The surface packer is more apply at not easy drill site. Usual the surface packer with low pressure nipple, because the injection work do not need high pressure. The surface adhesive packer can be use at horizontal or vertical situation.
We have two type surface packer, one is metal material and another is plastic adhesive packer.
The metal aluminum surface adhesive packer using high quality materials, which have high strength mechanical and corrosion preventive.

Plastic surface packer is made of PP, which have high strength mechanical properties and wear resistance.

Adhesive packer is better chose low pressure for epoxy injection, because the glue strength at concrete is not large enough. Low pressure is easy for opening grout injection.
