This method is suitable for repairing concrete cracks with crack width of 0.2-0.3 mm. It is to inject adhesive into cracks to improve their waterproofness and durability. For incomplete cracks, grouting method is difficult to inject slurry into the interior. When the injection pressure is too high, it is possible to expand the crack width. Therefore, at present, low pressure and low speed injection methods are widely used.
