Core Drilling

You should be as precise as possible with your measurements. You’ll need to have an exact, correct layout before we begin cutting to ensure the desired final opening dimensions. Once an opening is complete, there’s no give to the concrete. Important note: use rough dimensions where applicable, such as egress windows or door installations. If you use the exact dimensions of your window or door, it’s likely it won’t fit.

When drilling cores, pipe size and core bit size are not the same thing. A four-inch pipe will not fit in a four-inch core. You need to measure the outer diameter of the pipe being installed, add the necessary clearance, then calculate the required core size. Our operators don’t handle the coring dimensions and will drill the core size you request. Consult with our dispatcher when requesting service to ensure we have the proper size core on hand to complete your job.

Yes. The condition of the jobsite may require us to consider other factors.

We’ve cored over 70 feet deep in a foundation and cored over a 20-feet-thick wall. Distance above the slab or in front of a wall, as well as general access, factor into what is feasible. Contact one of our team members for more details.

Stone: yes. It’s more challenging to anchor to an irregular surface, but we can get the job done.
Dirt: no. For coring through dirt, you should contact a unidirectional boring company.

Yes. When the area on top is not accessible, we’re able to core upside down.

Yes. Please contact us to determine the best option to do your job.

Yes. Coring is a great solution for making round holes. We can drill in floors, walls and ceilings using special diamond-tipped coring bits ranging in size from under an inch to 84 inches or larger. If you prefer a square opening, we use other equipment such as handsaws, ring saws or wall saws depending on the size and depth of cut.

Yes, however it typically takes longer to do the job in freezing cold temperatures.
