Crack injection

APPLICATION OF POLYMER PACKERS

The cross sliding valve of the lamella drive-in packers prevents the material from escaping after the injection process.

APPLICATION OF ADHESIVE PACKERS

The packer is glued over the crack with a mixture of polyurethane resin or epoxy resin and possibly an adjusting suspending agent (to increase the thickness). Ensure that the opening of the packer is directly over the crack and the injection channel of the packer is not blocked. Adhesion packers are mainly used on buildings, where no drilling is permitted (normally thickness of structural elements = distance between packers) because of structural reasons (e.g. prestressed concrete).

Information

Adhesive packers available as metal or polymer packers

The adhesive bond between packer and structural element surface is essential

The adhesive tensile strength of the surface and the characteristics of the adhesive (sealing material) have a significant influence on the possible injection pressure

Applications

  • Dry structural elements
  • Structural elements with tight reinforcement
  • Prestressed concrete
  • High pressure injections up to max. pressure of 60 bar or low pressure injection up to
    10 bar

APPLICATION OF WEDGE PACKERS

Wedge packers are driven directly into the crack, usually from 1-2 mm width, and then injecting the injection material (injection). No time-consuming drilling work is needed. The wedge packers are made of metal or polymer.

Advantages

  • Timesaving due to reduced number of work steps on placing the packers
  • The wedge packer is driven directly into the crack, (no time-consuming drilling work needed)
  • The packer can be easily removed after the injection work
  • For the use of steel wedge packers the minimum crack width is 1.5 mm

APPLICATION OF SELF-INJECTING DEVICES

The self injecting device is used when the injection process must be carried out at low pressure (approx. 1 bar) and over a longer time period to ensure a successful result.
