Crack injection by pressure injection on dry or wet cracks

Dry or wet cracks can be sealed permanently with KOSTER injection materials.

KOSTER KB-Pur 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.

KOSTER KB-Pur IN 3 is used for structural bonding of cracked or damaged building elements. KOSTER KB-Pur IN 5 is a very low viscosity polyurethane injection resin with a very long pot life. It is especially suitable for injection into very small and fine cracks.

KOSTER Micro Grout 1C is a mineral injection material which is used 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 KOSTER injection resins are installed with the KOSTER 1C Injection Pump via injection valves called “Packers” into the crack. 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.
