In construction projects such as tanks, elevator shafts, water pipes, tunnels, etc., water leakage often occurs due to the following reasons:
- The construction quality at the expansion joints is not satisfactory, and the stop joints are not good, there are no Waterstop panels at the construction stop joints.
- The concrete surface is porous
- Pouring concrete into walls with large lengths without expansion joints, causing concrete cracking
- Concrete pipes are sinking and cracking
METHODS OF IMPLEMENTATION
The processing process includes the following basic steps:
- Survey the current status of water leaks to find the cause of the problem
- Design construction methods
- Approve construction methods
- Done at construction site
CONSTRUCTION METHOD OF HIGH PRESSURE EXPANDING ADHESIVE PUMP:
Basic steps:
Step 1: Check and clean the leaking surface.
Step 2: Drill a hole at the leak point, place a water pipe horizontally to reduce water pressure at other leak locations (only use for strong leak points).
Step 3: Place the 1-way valve into the drilled hole and turn clockwise until the valve sticks tightly to the concrete.
Step 4: Blow away the dirt on the surface of the leak point to create the best conditions for injecting glue inside the leak point.
Step 5: Pump PU glue SL 668/SL 669 inside the crack using high pressure pump SL-500/.
Step 6: Cleaning: when the glue injection job is completed, after 1 hour, you can remove the one-way valves, flatten and clean the surface of the leak point.
APPLICATION
- Handling water leaks in basements and hydroelectric power plants.
- Handling water leaks at expansion joints - settlement joints.
Note: PU pumping technique - SL 668, SL 669 requires complexity as well as high processing experience in waterproof environments.
