Reasonable prices concrete core drilling for South Hill, Lake Gaston and of course Petersburg, Virginia.

Professional Core drillers with 35 years experience core drilling reinforced concrete walls and floors.

Specializing in boring holes in reinforced block walls, solid concrete walls, foundations, concrete sidewalks and, concrete floors from diameters of 1 to 14 inches with depths of up to 36 inches. Many projects are for commercial services where a penetration or opening is needed to pass through a water pipe, electrical conduit or wires, HVAC air ducts as examples.

Ever wonder how the tables and chairs that look like they are planted in the concrete or tile found at many restaurants get to appear that way? Core drilling is many times a preferred method for installing such things. At some point, a designer or owner decided on a plan to make the business, or in some cases, even homes, have embedded tables and chairs as a way of seating for the dining or entertainment area. This is even more popular with swimming pools and swim-up bars and tiki's that some like to have.

Here in North Carolina we have core drilled holes for restaurants tables and chairs for years. A recent trend we would like to note is the before the great pandemic most of these types of core drilling projects took place indoors, usually through commercial-grade floor tile or carpet, down into the concrete sub-floor below. Now coming to the second winter of the pandemic most of these types of projects are taking place outdoors. We assume to limit the number of people inside the building.

Pretty blue core holes

the pictures are from two different jobs near the Raleigh area, one in Cary the other in Apex, NC. The second picture, though a bit sun bright, shows the concrete pad where the coring took place. The BlueFlag color blue dots are the core drill holes before we took a 3-pound hammer and a chisel and popped the cores so they would break and come out the holes. As you can see the pattern right now doe not make much sense. But once the table is installed and the chairs are put in place then it all comes together to make the dining areas that we have gotten used to in these modern ages. Years ago our providing contractor had asked that we core all the way through the subfloor and hit the dirt below, or in most cases in North Carolina, clay or sand. Recently the requests are to stop just short of busting through to the bottom so that it makes pouring the liquid pourable anchoring cement into the holes not seep out through the bottom into the mud and make pouring the dining furniture a long endeavor. Of course, this is an ole handrail installer's trick to save on wasting anchoring cement into porous holes,..yea we suggested it.

Commericial Restaurants often use core drilling.

Of the number of projects we do that Commercial restaurants make up about 10 percent of the work we perform each year. Other types of uses that a restauranteur might find a need for a core drilled hole are floor drains, electrical floor boxes, barriers, and bollards.

Recently the number of core drill holes we have been drilling has been for upgrading of 5g fiber service for individual buildings. There is not much difference in the holes for any other type of utility service except because the data lines that are being installed themselves are usually small, meaning that typical 3-inch penetration will accommodate more than an entire buildings' worth of data lines.

Updating the Fayetteville NC Veterans hospital

While we provide professional core drilling services Fayetteville NC. When we are able to be part of something as important as helping armed force veterans we are proud to be of service. The VA hospital on Ramsey St. in Fayetteville is a particular older building. Made of brick and mortar on the outside facade. The interior floors where we core drilled happens to consist of precast concrete planks that are barely 4 inches thick. You can imagine that it did not take long to drill each hole. The real challenge was the difficulty of keeping dust and water under control so as not to contaminate the air filtration system that is so important to patients with respiratory ailments. Of course, we have had plenty of practice at not making a mess while we are performing our task of boring perfectly round holes into precast floors. But still, it's not what you have done before but what you are doing now that dictates the moment.

This not the first hospital we have core drilled. Having already performed the same type of service for the Concord, Salisbury, and some of the Charlotte area hospitals we were familiar with the protocol. In this time of world pandemic, we naturally had to be masked, but more than that we had to be perfect and not drop even a drop of water or rock down onto the room below which in many cases were occupied by patients of the facility.

Not a rock dropped.

The natural way of things is that when core drilling concrete on a second story floor that the rock drops to the floor below. Luckily we have several methods of catching the rock in case gravity does win out over our countermeasures.

These are the simplest and most common methods used to catch rocks when core drilling.

Core drilling the Cumberland county landfill

Additional Core drilling projects we have recently done in Fayetteville this year is coring twelve-inch holes in water drain basins at the Cumberland county landfill for new sewer and wastewater runoff at the landfill. The Fayetteville landfill is located on Ann St, Fayetteville, NC.

Coring drilling on Bragg Blvd, Fayetteville, NC

Another recent project is 4-inch core drill holes for homeowners right off of Bragg Blvd. The local plumber was remodeling a bathroom and need core drill holes size 4-inch for new shower drains.

Core drilling the Durham VA hospital

turns out a few months later we core drilled some 3-inch holes in the foundation of the Durham Veterans Administration Hospital in Durham, North Carolina. These particular penetrations were for new natural gas piping to be installed into the hospital. Often we are called upon to perform core drilling for the utility companies such as the local power company, internet providers that are running new data cabling to the hubs that power the internet. This, of course, is now September 2021, and when on hospital grounds these days you must practice social distancing to be safe, so everyone on our crew masked up and drilled safely.

This is a small commercial core drilling job we took on that happened to be located on Fitzhugh St. The task to drill three 3-inch holes in a pre-cast floor from the 3rd floor to the 2nd, and then from the 2nd to the parking garage below.Not too hard of a job though every core drilling operation is a dangerous prospect to take on. We accomplished completion by using a trusty garden pond water pump that runs off of 120 volts and a 5-gallon bucket of cooling water to keep the bit sharp. The floor as can been seen is has a ceramic tile covering to enhance the usefulness of the utility room. Diamond embedded core drill bits have no problems cutting tile leaving a token core of the top layer of the floor. A talisman of the core drilling project we did in near downtown Richmond VA. Core drill slurry was not a problem as we caught all of it with a simple shop vac.

Not your typical foundation wall, commercially built foundation walls are full of rebar tied together inside which makes a 10 inch core drill hole in a reinforced concrete wall a challenge. On this particular project, we used one of the older used 10-inch core drill bits that were in the job-box that morning.Like any other type of work, part of a core driller's duties includes using the right bit for the right job. That is not always a new core drill bit as that would not be very profitable for the core drilling company to do. And, in deciding which bit to use to is always from oldest most used bit to the newest.The drilling, or core drilling or even boring if you will, took about 15 minutes once everything was set up. With plenty of cooling water from our onboard tank, we were able to make a perfectly smooth 10-inch hole in the foundation wall. Getting close enough for power and water was essential. A 10 inch hole takes a stout drilling motor that can stay effective through out the drilling process. Usually this is going to be a 20 amp or larger core drill motor that has enough torque to turn the heavy core drill bit and let the diamond teeth do their magic.

cost of drilling a 10 inch hole

this could be a tricky question as the wall was 16 inches thick. The total cost in the end amount to 2300 dollars. As there were 3 10 inch cores to do for this particular core drilling project in Raleigh NC.
