In case of water active leaks, a combination of KOSTER KB-Pur IN 1 (very fast foaming after contact with water) and KOSTER KB-Pur IN 2 (used for permanently sealing the crack) is applied.
KOSTER KB-Pur IN 7 is also a very fast foaming injection resin which creates a permanently elastic seal. KOSTER KB-Pur IN 7 needs to have contact with water to build foam and cure.
All KOSTER injection resins are installed with the KOSTER 1C Injection Pump via injection valves called “Packers." Depending on the application, different packers are available.
KOSTER Impact Packers 12 are installed very quickly and are recommended for low to medium pressure.
KOSTER Packers and KOSTER Superpackers are used for all applications from low to high pressure.
KOSTER 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.
