Core Drilling

Core drilling is the use of a portable drill press to drill holes into concrete. The bits used are either diamond or carbide tipped. The holes can be drilled perpendicular to the concrete or drilled at almost any angle. Core drilling is used for creating a hole in concrete walls or floors for pipe penetrations, bollard installations, testing the depth of the concrete, testing the quality of the concrete, new holes for anchors, drill out existing anchors to replace them with new anchors, etc.

Typical Core Drill

 

Coring up-side-down

 

Coring a wall

 

Currently have bits up to 38" diameter. We can do larger holes if needed.

 

Some locations require our providing a template to mount the core drill to in order to reach the desired location.

 

We were asked to drill two holes 100 feet deep in a salt mine for them to test the salt cores.

 

Since the bit is hollow, we can drill over existing anchor bolts, extract them, and set new anchors in the old anchor's location.

 

Williams Form Engineering makes an anchor, S-9, that requires the bottom of a cored hole to be undercut or bell-bottomed.  We have the tools to accomplish this requirement.
