High Pressure Grouting Method
The high-pressure filling and leakage-free leakage engineering method is the most common leakage-prevention technology for repairing the leakage of current repairs. The high-pressure injection and leakage-prevention engineering methods used in buildings, tunnels and even basement and MRT stop-leakage engineering methods are numerous.
In the widely used, there are still many defects, such as: lack of perfusion pressure, needle misplacement, etc.
To enhance the effectiveness of leak prevention and ensure high construction quality, it is crucial to utilize a reliable and efficient grouting machine working at optimal pressure, the following description will be high-pressure injection method.
Construction Flow Chart
Drill Holes
Drill the hole alternately:Stagger on both sides ofthe crack; the gap between the holes should be25cm-30cm.
Drill the hole at angle of 45 degree onto the concrete surface.
Cleanig of bore holes.
Setting Perfusion Packer
The depth of the drilled hole must be at least half of the thickness of the concrete
Tighten the grouting filler
Vesicant Perfusion With High-Pressure Groting Machine
Direction of motion
From bottom to the top
From left to the right
Alternating left and right
Vesicant Preservation
More slop will be poured repeatedly, at least 2-3 times, to completely fill the holes

Leak of Construction Crack
Honeycomb Leak
Leak of Ring Slice
Drill holes to the half of the structure around 5CM to 10CM on the left or right side of the underneath of the crack, the diameter should be 25CM to 30CM. 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.).
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.
After the perfusion finished, the pinhead can be taken away.
drill holes to 2/3of the structure around 5CM to 10CM on the left or right side of the underneath of the crack, the diameter should be 25CM to 30CM. 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.)
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.
After the perfusion finished, the pinhead can be taken away.
If the leak can’t be improved, can use the hydrophilic vesicant to mend it.
drill holes per 25CM-30CM.
The depth should be the two thirds of the structure.
inject the instruct until the liquid penetrades from the inside.
inject hydrophilic stanch material, the leak can be solved out
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.
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.
Leak of Grouting Holes: drill hole of 5MM diameter on the cover of the grouting holes, and infuse hydrophilic stanch material.
