Solve water leaking without hacking/disturbance on water leaking source.
Also known as PU Grouting or PU Injection. Treatment method of drilling 13mm width holes (point) at the soffit of the leakage area and install packers (connector between concrete slab and high pressure pump) along the leaks area. Then force expanding chemical liquid to travel along leaks area by using high pressure pump. Chemical reaction occurs inside concrete when it contact with water/moisture and becoming expand 40-50 times to block passage of water and filled up honey comb.
Treatment are conducted on leaking area only, and there is no disturbance on other places (except sound during drilling process).
