DESCRIPTION

KÖSTER Injection Barrier is an ultra-fast curing 2-component mortar used to create a cementitious layer to prevent the loss of injection material during area injection e.g. with KÖSTER Injection Gel G4. The mortar can be applied either by brush or trowel and has exceptional early strength development. After application of KÖSTER Injection Barrier, masonry can be injected already after 60 minutes. With the addition of KÖSTER Mortar Boost to the powder component, the consistency can be varied within the first 20 minutes from firm to plastic depending on the amount of the added liquid component. Due to its high concentration of polymer, KÖSTER Injection Barrier has a very high adhesive strength to the substrate. KÖSTER Injection barrier cures free of tension and shrinkage. Adding KÖSTER Turbo additives to the mixture can accelerate or delay the setting time.

AREAS OF APPLICATION

KÖSTER Injection Barrier is used to create cementitious layers on mineral surfaces such as masonry, concrete and plasters in order to create a barrier against outflow of injection products. KÖSTER Injection Barrier is applied either before the drilling of boreholes or after the installation of packers. When applied after the installation of packers, KÖSTER Injection Barrier is applied around the packers using a trowel or a small brush. KÖSTER Injection Barrier provides an excellent substrate for the application of further cementitious products such as restoration plasters.
