Polyurethane Used In Structure Cracks Leaks And Construction Joints Leaks
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 top 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, as a general structure of the crack is irregular, so special attention must be boring holes and rupture surface, filling will have effect.
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.
