Incomplete embedment
On a project where the contractor has drilled holes that are too deep for the anchor. If the hole is filled with epoxy (HY200 in this case), what is the consequence of not inserting the anchor to full extent of the hole?

Hi Tyler,
For drilling a hole deeper than what is in the technical data for HIT-HY 200, please consider the following:
- How will you ensure the anchor element does not sink to a further embedment depth within the hole when both inserting the element and torquing it?
- HIT-HY 200 is a fast curing anchor, something to keep in mind when dispensing into a deeper hole the adhesive is its working time (the time an anchor element can be inserted into the adhesive)
- The concrete thickness requirement would need to be evaluated as it may have changed with a deeper hole
- Its effective embedment could be impacted and thus the load capacities of the system could be impacted
Ultimately, all design decisions are at the discretion of the Engineer of Record (EOR) on the project. The engineer on the project should consider engineering judgment and on-site evaluation to determine suitability for the application.
Regards,
Emily

Thanks for the response, Emily. However, I don’t think I was clear enough about our issue. The designed embed depth was 5” with #5 rebar anchor. The contractor drilled the hole 9”. To avoid cutting longer rebar they asked to partially insert the rebar into the hole. This would leave a 4” space (filled with epoxy) behind the anchor.
Is this void acceptable using HY200?
