System based on dry cement-mineral mix in constructional package (cathead) for dead-ending of embedded parts
Field of application:
For dead-ending steel reinforcement in concreter or in other strong constructions. Can be used for dead-ending of machinery, for attached implements, for making arc strengthening in shaft sinking etc.
Common characteristics:
- Appearance: waterproofing cathead with special mix
- Proportion: defined by current tasks

After mounting the anchoring system has resistance to high temperatures, salt and other aggressions.
Temperature of application: äî -5 °Ñ.
Work in concrete with any moisture (including underwater), not toxic, not combustible.
Retention cycle in hermetic package is to 12 months.
APPLICATION INSTRUCTION:
- Opening is drilled in a massif with necessary diameter and total depth (blast hole).
- Blast hole is cleaned from dust and grit, for example with compressed air.
- Before anchor putting walls of blast hole are dumped with water. Remainders of water are moved off.
- Cathead is submerged into water and kept during calculated time depending on Ø of cathead but no more than 60 s.
- Catheads are input but no later than 2-3 min after its dumping in blast hole in necessary quantity.
- Attachment is located in blast hole opening and driven in over catheads to home or located with slow-speed drill. Wet mix at this moment is being filled to all space between from anchor and walls of concrete. The rest of it is pressed out.
- Unloaded anchor is left for 30 minutes.
