insensitive injection-liquid, based on high strength
As an injection resin with good adhesion to dry con-
crete, mortar, stone, steel and wood. Sikadur®-52
LP(IN) is used to fill and seal voids and cracks in struc-
tures such as bridges and other civil engineering build-
ings, industrial and residential buildings, e.g. columns,

Sound, clean, free from oil and grease and surface
Pre-treatment for good bond:
Concrete, mortar, stone should be thoroughly pre-
pared by high pressure water jetting or mechanical
means such as grinding, chiselling etc. Cracks must be
cleaned to remove dust with compressed air.
