Polyurethane resin, in its cured state, does not have a negative impact on human health and the environment.
Component A: Low hazard in terms of its effects on the body, but it can cause irritation if it comes into contact with the skin or eyes.
Component B: It can cause irritation if it comes into contact with the skin or eyes, and it is harmful if inhaled.
Component Ratio:
Component A: 100 volume parts.
Component B: 100 volume parts.
Component A should be mixed for 10 minutes before use.
Component B should be mixed for 10 minutes before use.
Ambient temperature should be between +3°C and +30°C.
Check the surface for hidden cracks, cold joints, and other leaks.
If necessary, remove loose layers of brick, concrete, or plaster and clean the joint.
Identify the locations of cracks and voids for injection. The diameter of the holes should exceed the diameter of the injector by 1-2 mm. Mark the injection centers near each crack or cold joint, the source of the leak.
To eliminate high-pressure leaks, first inject Himtrust PU elastic foam, and after 12 hours, inject Himtrust PU injection resin.
For injection into a joint or crack:
For injection into the body of the structure:
For veiled waterproofing:
Do not work near open flames.
Ensure ventilation and fire extinguishing measures when working with the resin in a closed room.
Use personal protective equipment: special clothing, gloves, footwear, protective goggles, respirator.
If the product gets on the skin, remove it with a cotton swab or tissue and then rinse the skin with warm water and soap. Consult a doctor if irritation persists.
If the product gets into the eyes, rinse with plenty of water. Seek medical attention if irritation occurs.
Injection should be carried out using a single-component injection pump for resins.
Injection work should be done until the crack or joint is completely filled, with neighboring packers without a top coupler with a check valve to allow material to exit during the filling process.
For quality sealing and maximum density, it is recommended to perform re-injection after 0.5-1.5 hours.
Before moving to the next injector, perform a control injection into the previous one.
Before performing re-injection, in case of complete polymerization of the material, carefully remove the top coupler with the check valve and clean the channel in the packer using a drill and a fine drill bit.
On vertical cracks, work from bottom to top, and on horizontal surfaces, work sequentially.
After polymerization of the injection material, remove the packers and fill the holes with a sealing compound based on dry construction mixes with water impermeability rating W8.
