Can I use a 5/8in. HAS-E-55 Anchor with HIT-RE 500 V3 epoxy in 4in. deep concrete wythe of a 4in-3in-4in wall panel. The middle 3in. being insulation? I am looking to use 3.25in. embedment depth, which will leave 0.75in. concrete beyond the embedment depth. Concrete blow-out from behind if not a concern in my case, since the insulation is rigid.
Hi Abdul,
PROFIS Engineering Anchoring to Concrete pulls values directly from the corresponding product’s ICC Evaluation Service Report (ESR). The minimum concrete thicknesses published in ICC ESR-3814 for HIT-RE 500 V3 are established based on testing per ICC-ES Acceptance Criteria AC308. Based on testing to these criteria, the minimum concrete thickness is needed to prevent concrete splitting or spalling upon installation. For conditions outside of the published report, including layers of other materials between or behind the concrete, anchorage is ultimately at the judgement of the Engineer of Record. On-site testing may aid in that judgement.
Please reach out to hnatechnicalservices@hilti.com for any additional questions.
Kind regards,
