Need to anchor 4" thick stone slabs to the concrete floor of a discharge water channel. Channel will mostly be dry, but in a storm event a column of water 8 to 10 feet tall will suddenly be discharged and run over the anchored stones. Stones must remain in place for years to come. City doesn't want to perform any maintenance or be replacing loose or fallen stones. Joints between stones will be grouted. Exposed surface of stones will be rough, not smooth. This may increase tear off forces on the stones by the water rush and debris within it. Any recommendations for the anchoring system to use?
Hello,
For anchorages to concrete, engineers typically consider Hilti's HIT-HY 200 V3 or HIT-RE 500 V3. Technical information for the HIT-HY 200 V3 can be found in Section 3.2.2 and for the HIT-RE 500 V3 can be found in Section 3.2.3 of Hilti's Anchor Fastening Product Technical Guide. Both anchoring systems are able to be used in submerged conditions.
If you would like to discuss the application further, please reach out to hnatechnicalservices@hilti.com or give us a call at 877-749-6337.
