Use method

Secure the bag at about 1 metre height, relative to the pre-drilled holes for the injection of the chemical barrier resin, by nailing directly on the masonry, or preparing an adequate wooden support. The distance between bags will have to correspond to the distance between the pre-drilled holes. Connect the appropriate rubber provided with the bag itself. Insert the other end of the tubes directly into the holes provided for the chemical barrier, at the foot of the masonry. Pour the resin in the bags until they are completely filled. Refill the resin in the bags until the complete saturation of the relevant hole ("until refusal").
