I want to build groove for placement of Hydromechanical gated which has to be oertaed under 30m water head in 100 year old stone masonry dam. Please advice on the products which may be used & the procedure we've to follow? TIA
Tarun:
Hilti does not have any cutting or demolition tools that can be used underwater since they are electric. Pneumatic/air tools may be more suitable for your application.
To anchor the new gate you may want to consider using Hilti HIT-RE 500 V3 epoxy which can be used underwater up to 50m deep. Field testing is recommended since natural stone base materials may vary and we have not tested HIT-RE 500 V3 in natural stone for use in North America. If the project is location outside of North America I suggest that you contact your local Hilti technical representative for further assistance.
HIT-RE 500 V3 Product technical inforamtion available at: https://submittals.us.hilti.com/PTGVol2/#140
Let me know if you have any other questions.
Regards,
Randy
