Masonry injection
With the masonry injection leaking structural elements covered with earth can subsequently be sealed from the inside. Depending on the building material composition and pore structure, a continuous sealing layer in the structural element (masonry) is created. By injecting suitable materials such as low-viscosity gels or resins, the water transporting capillaries are sealed.
Application aim
- Sealing of structures in contact with the ground or inundated with the ground from the inside out
 - Subsequent sealing of element walls
 - Filling of cavities and cracks (special proof of suitability required)
 - Subsequent sealing of leaking expansion joints
 - Subsequent injection of expansion joints between joint tape and water-resistant component surface
 
Filling material
- Acrylate gel
 
Demands on the injection packers
- Safe retention in the structural element during the injection at pressures depending on the injection method
 - Corrosion resistance of elements remaining in the structural element
 - Absperrmöglichkeit
 - Shut off option
 - Cross section adjusted to the required delivery and flow properties of the injection material
 - Check valves for low opening pressure
 
Demands on injection devices
- Forced delivery of the components at reliably adjustable mixing ratios
 - Powerful mixing head with check valves and cut off cocks
 - Mixing line suitable for the injection material
 - Separate high-pressure rinsing pump
 - Measurement technology for monitoring and documentation of injection and dosing processes - DESOI Flow Control II, (please request consultation and brochure!)
 

Masonry injection in the building component
- The sealing layer is created in structural parts which initially have not been planned to be sealed
 - The water transporting capillaries are sealed
 
Masonry injection in cavities
- The sealing layer is created in technologically conditioned parting planes, e. g. in cavities between double walls
 
Crack injection and injection of hollows
- Very often partial crack injections and injections of limited hollows have to be carried out, e. g. raster injection
 
Procedure
- Boreholes are drilled into the leaking structural element from the inside to the outside, up to approx. of the thickness of the structural element, at a slight angle of inclination
 - The borehole pattern depends on the geometry of the structure
 - The packers through which the injection material is injected are placed in the boreholes
 
Extracting tool for lamella drive-in packer
Combine your extracting tool
In order to remove lamella drive-in packers from the construction element there are different extracting tools available, varying to the type of the packers. The extracting tool is screwed in or on the lamella drive-in packer and the impact weight is moved powerful into the pull-out direction. Step by step the packer is removed from the construction element.- Basis: Pull rod
 - Weights available individually between 1 kg and 1.4 kg
 
Advantages
- For the extraction of different types of packers
 - All adaptors can be combined with both pulling devices according to the application
 - Reusable product
 - Easy handling
