Single Component Hydrophilic Polyurethane Grouting Material
● Structure cracks leaks
At the lowest point of the crack left or right 5cm-10cm oblique 45 degree drilling to half the depth of the structural body depth, step by step from the lower to the height of the drill, the pitch is 20-30cm is appropriate, drill again after the height of the buried Water stop needles and to tighten the fixed, due to the general structure of the crack is irregular, so special attention must be boring holes and rupture surface, grouting will have effect.
Fold construction joints leaks
At the lowest part of the construction joint, the left or right 5-10cm oblique 45 degree drilling to the degree of drilling to half the depth of the structure thickness, step by step from the lower to the top of the drilling, pitch is 20-30cm is appropriate, drilling highest Department again after the laying of water-stop needles and tighten the fixed.
Folding honeycomb leaks
In the honeycomb range, every 25-30cm drill a hole, the depth of the thickness of the structure of the body is appropriate, and then buried stopwatch needle and tighten the fixed.
Folding tunnel ring water stop
Ring cracks seepage water: the hole directly before the crack at the hole drilling depth must exceed the ring thickness, buried water-stop needles and tighten the fixed after the injection of special agents until the grouting is completed, and then at the ring cracks left Or right 5-10cm oblique 45 degree drilling to the ring thickness of 1/2 deep, embedded water stop needle, again injected into the slurry to the body surface seepage, you can remove the water stop needle.
Seepage between loop and loop: drilling before seepage between loop and loop, the depth of drilling must exceed the thickness of loop, injecting the agent into the slurry after embedding the stop needle to exudate the slurry on the surface of the structure, Completely cured to remove the water stop needle. Grout hole water seepage: Directly hole in the grouting hole cover, and then injected into the hole medicine, until the material is fully cured to remove the water stop needle.
