High-pressure Grouting Stanch Method

Chaping & Leaking of Framework

  1. Drill holes to the half of the structure around 5 CM to 10 CM on the left or right side of the underneath of the crack, the diameter should be 25 CM to 30 CM. When it reaches the highest point, the stanch pinhead can be put inside. Since the shape of rimous normal instruction is unequal, the hole should be crossed with the crack surface, the injection can work well.(for better result, the distance of the holes can be shorten.)
  2. After the setting of the stanch pinhead, inspect the instruct intension first; if the intension is not strong, please use hydrophilic vesican to inject the instruct until the liquid penetrades from the inside.
  3. After the perfusion finished, the pinhead can be taken away.

Leak of Construction Crack

  1. drill holes to 2/3of the structure around 5 CM to 10 CM on the left or right side of the underneath of the crack, the diameter should be 25 CM to 30 CM. Since the shape of rimous normal instruction is unequal, the hole should be crossed with the crack surface, the injection can work well.(for better result, the distance of the holes can be shorten.)
  2. After the setting of the stanch pinhead, inspect the instruct intension first; if the intension is not strong, please use vesican with hydrophobicity to inject the instruct until the liquid penetrades from the inside.
  3. After the perfusion finished, the pinhead can be taken away.
  4. If the leak can’t be improved, can use the hydrophilic vesicant to mend it.

Leak of beehive

  1. In the scope of beehive, drill holes per 25CM-30CM. The depth should be the two thirds of the structure, then set the pinhead and turn close.
  2. After the setting finished, please use hydrophilic vesican to inject the instruct until the liquid penetrades from the inside, then inject hydrophilic stanch material, the leak can be solved out.
  3. After the perfusion finished, the pinhead can be taken away.

Leak of Ring Slice

  1. Leak of Ring Slice: drill holes around the location of leak, the depth should be thicker than that of the ring slice. After the pinhead put, please inject hydrophilic vesican; then put the pinhead after drilling holes to 2/3of the structure around 5CM to 10CM on the left or right side of the underneath of the crack, inject the hydrophilic stanch material.
  2. 2. Leak between Ring Slices: drill holes on the leak between the ring slices, the thickness of the holes should be thicker than ring slice, after put the pinhead, please inject hydrophilic vesican. Inject the stanch material, after perfusion.
  3. Leak of Grouting Holes: drill hole of 5MM diameter on the cover of the grouting holes, and infuse hydrophilic stanch material.



On each side of grouting cover, but do not be close to the crack or the cover which will flake off when drilling holes.

When the wholes are filled, they can be filled again. If the holes need more slop for the crack, they need to pour 2 to 3 times.
