In case of water actively leaking from a crack a combination of KÖSTER IN 1 (very fast foaming after contact with water) and KÖSTER IN 2 (used for permanently sealing the crack) is applied.
KÖSTER IN 7 is also a very fast foaming injection resin which creates a permanently elastic seal. KÖSTER IN 7 needs to have contact with water to build foam and for curing.
All KÖSTER injection resins are installed with the KÖSTER 1C Injection Pump via injection valves called “Packers” into the crack. Depending on the application, different packers are available.
KÖSTER Impact Packers “12” are installed very quickly and are recommended for low to medium pressure.
KÖSTER Packers and KÖSTER Superpackers are used for all applications from low to high pressure.
KÖSTER One Day Site Packers have an extra valve so that the upper part of the packer can be removed directly after injection and the hole plugged. The borehole stays pressure sealed.
Always adhere to the specifications in the respective Technical Guidelines.
