Elastic and structural crack injection by pressure injection on dry or wet cracks

Dry or wet cracks are sealed permanently with KÖSTER injection materials .

KÖSTER 2 IN 1 is the standard material for waterproofing cracks. The material forms a foam when it comes in contact with water and stops it by reacting with the water or displacing it. A second injection using the same material permanently and elastically waterproofs the crack.

KÖSTER KB Pox IN can be used for structural re-bonding in dry or wet cracks.  

KÖSTER IN 5 is a very low viscous polyurethane injection resin with a very long pot life. It is especially suitable for injection into very small and fine cracks.

KÖSTER Micro Grout 1C is a mineral injection material which is ideal to fill voids and cracks of medium width. The material has excellent adhesion properties even to damp substrates. It also possesses a very high compressive strength after 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.

The KÖSTER Superpackers are used for all applications injecting with low and high pressure. KÖSTER One Day Site Packers have an extra one-way return valve. The bottom portion of the packer prevents the injection material from flowing back out of the wall so that the upper part of the packer can be removed directly after injection and the borehole stays pressure sealed. The drill hole can be sealed immediately after the injection works.

KÖSTER Micro Grout 1C develops an excellent bond to wet substrates and has a high final compressive strength.

Always adhere to the specifications in the respective Technical Guidelines.
