With the curtain injection leaking structural elements covered with earth can subsequently 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.
- Packers (steel packer)
- Drive-in packer (polymer packer)
Demand for the injection packer
- Safe retention in the structural element during the injection at pressures depending on the Injection method
- Corrosion resistance for elements remaining in the structural element
- Shut off option
- Cross section adjusted to the required delivery and flow properties of the injection material
- Check valves with low opening pressure
- The borehole pattern and borehole depth depend on the construction and geometry and are determined by the expert planners.
- The structural element is not completely drilled, but as close as possible to the outside edge of the structural element.
- Bore holes are drilled into the leaking structural element from the inside to the outside, up to approximately 2/3 of the thickness of the structural element, at a slight angle of inclination.
- The packers are inserted into the bore holes and injected.
Applications for subsequent sealing
- Curtain injection into the ground
- Injection of joints
- Injection of building spaces
- The low-viscosity, liquid injection material displaces the water present, and builds an elastic seal or an elastic injection body together with the surrounding building.
