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 IN 3 is used for the structural bonding of cracked or damaged building elements. 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.

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.
