RE: Testing for Anchor Bolt Embedment

[Subject Prev][Subject Next][Thread Prev][Thread Next]
If it's a wedge anchor, maybe you could drill one out and see what you've got. (See attached link). You might also be able to do a pull test on one without removing it.

Subject: Testing for Anchor Bolt Embedment


I am reviewing the anchorage of a hospital emergency generator with 40 - 3/4 inch diameter cast-in-place anchor bolts but the drawings do not show the embedment depth.  Does anyone know of a field test to determine the embedment depth?  I am thinking there must be some type of sonic test that could measure the rebound and determine the bolt length.  Any ideas?
