Concrete coring and sawing are done with diamond-tipped drill bits and blades. It’s the least destructive method for removing concrete or forming penetrations in concrete surfaces, because it causes the least amount of structural damage to the rest of the concrete. The diamond-tipped blades will also cut through reinforcing steel inside the concrete.
The entire operation is quick, quiet, and environmentally friendly. Health and safety risks can be easily identified so they can be minimized or even eliminated, but contractors and building owners must make sure they get the right information from a qualified professional before they make any structural modifications.
Common Methods for Cutting Reinforced Concrete
A number of methods can be used to produce clean, dust-free, and accurate cuts in reinforced concrete and other building materials. Some of them can include concrete sawing inside walls and soffits, as well as wire and ring sawing. Other methods used for cutting concrete can include the following:
- Handheld Sawing — Hand saws can be used in a number of applications (from saw-cut floors and concrete precast walls to concrete pipes and beams), but they also have the biggest potential to injure someone who isn’t trained in their operation. They’re often used in small spaces that are inaccessible to a floor saw. And while most hand saws are gas-powered, there are many (such as hydraulic, single-phase electric, and hi-frequency) that are more suitable for indoor use.
- Track-Mounted Wall Sawing — This method is used to cut concrete and to remove walls (mostly for the purpose of forming large openings for doorways or ducts for HVAC units). They can make very accurate cuts, and they can be controlled remotely so operators can be free from any possible dangers.
- Wire Sawing — A continuous loop of diamond wire is “wrapped” around the concrete, which is what makes this method so versatile. It can even cut through the reinforcing steel, but it’s not as accurate as other concrete cutting techniques. Like a track-mounted wall saw, a wire saw can be controlled from a remote location. They’re also very quiet, which can be helpful if they’re used in areas where noise levels have to be controlled (such as in hospitals or hotels).
- Floor Sawing — Also called road sawing, ground sawing, or flat sawing, this is a tool that all professional concrete cutting companies use with walk-behind machines. The blades can be in a number gas-powered and diesel saws from 18 to 54 horsepower (depending on the manufacturer). There are even three-phase electric saws that can be used for interior applications, which will eliminate the risk of carbon monoxide poisoning.
Concrete cutting is often used in construction projects where stone, terra-cotta, concrete brick, and cemented concrete blocks are the primary materials. It can be used to build a number of structures, which can include the following:
- Dams.
- Piers and wharves.
- Parking garages.
- Nuclear power plants.
- Sewage treatment plants.
- Chemical plants.
- Interstate highways and bridges.
On a smaller scale, concrete cutting can be used to make or enlarge doorways, window frames, and bulkhead openings. It can also be used to cut trenches for plumbing, sump pumps, drains, electrical conduits, and other utility lines.

The Purpose of Concrete Core Drilling
Concrete coring can be used to form penetrations inside precast panels, block walls, beams, and concrete floors for the purpose of installing the following:
- Plumbing service pipes.
- Electrical conduits.
- HVAC units.
Specialized tools can be used for deep-core drilling, which is typically used to form a round hole inside concrete or masonry for the purpose of performing a number of servicing and reinforcement procedures. They’re also used during seismic upgrades, where post-tensional rods can be grouted into the walls of buildings. The drill is used to remove a cylinder of material, which is called a “core.” It’s often used in the following applications:
- Walls, floor slabs, and ceilings where electrical and communications services, cabling, plumbing, and HVAC systems need to be installed.
- Slab and roadway holes for dowels, rebar tie-ins, or drainage systems.
- Recessed lighting and fixtures.
The process for coring a hole inside concrete is relatively simple. While you can find the equipment at your local hardware store, it doesn’t mean you should do it on your own. The last thing you want is to cause damage to your home, which will cost even more to fix than it would be to hire a professional.
Concrete sawing and coring are essential services for creating clean, controlled openings in concrete for plumbing, electrical, and structural needs. Understanding how the process works and when it’s needed can help you plan your project with confidence. This FAQ addresses common questions to give you a clear overview of what to expect.
Concrete coring is a precise and specialized technique that’s used to remove cylindrical sections of concrete from solid surfaces. This technique is important in a number of applications. Some of them can include testing the structural integrity of concrete, creating pathways for utility installations, and removing areas of damaged material.
Concrete coring is important because it can be used in a variety of ways and in many different settings. Here are some of the reasons why concrete coring can be useful:
It can facilitate testing — If you have just poured a concrete slab or believe that it may have been compromised, you can use coring to perform certain tests (which can range from compression stress, composition, and stability tests).
It allows for more precise concrete removal — Concrete coring is a precise technique, so you can use it to remove concrete in specific areas. As long as you don’t core in an unstable area, it can keep the remaining concrete stable.
It can be used to create paths for utility lines — It can give you a convenient way to create paths for utility wires and pipes. Instead of tearing out an entire wall, you can cut a relatively small cylinder that can be used to house the wiring. They can also be used to create manholes and to install chandeliers.
Be sure to speak to a professional for more information.
You can core concrete without water. But because it puts stress and pressure on the blade, it’s not recommended. The lack of water will also create more friction, which will heat up the drill bit and even damage it.
In most situations, you can core concrete to a depth of 14 inches. But with a specialized drill bit, it may be possible to drill deeper. Either way, the required core depth will depend on the purpose of the coring.
The techniques for concrete coring can vary according to the area that needs to be cut and the reason for the cutting. That’s why cutters use different cuts to achieve a specific goal. Here are some of the common techniques that are used to cut concrete:
Slab Sawing — This is often used in remodeling projects that involve concrete or asphalt surfaces. You may need to fix a new pipe or access a plumbing line under your floor.
Wall Sawing — As the name suggests, this technique involves cutting through walls and is commonly used in situations that require straight cuts.
Core Drilling — This technique can give you a good solution for when you need to make round holes through concrete. You can drill holes of any depth in case you need to install deep, cylindrical structures.
Wire Sawing — Sometimes, you need to cut or remove concrete surfaces that are too big. And because a one-cut process would be hectic, wire sawing can be used to reduce the larger surface into smaller and more manageable sizes.
Be sure to speak to a professional for more information.
Concrete cutting creates a lot of dust, which can reduce visibility and dirty the environment. It can even be harmful to your health. Concrete dust has silica. And if you’re exposed to it for long periods of time, it can lead to silicosis, lung cancer, and even tuberculosis. Concrete cutters have to spend a lot of time performing this task, which results in more extended exposure periods. And while masks are available to minimize dust exposure, the chance of dust inhalation isn’t completely eliminated. Dust from concrete rises in the air before it lands on plants and other surfaces, so you will have to clean many different areas. But wet sludge forms a damp mess or slurry, which you can easily sweep or vacuum.
Here are some of the reasons why you may need to cut your concrete:
To improve your outdoor drainage — If you live in an area that experiences a great deal of heavy rainfall, you may need to modify your outdoor drainage. Concrete cutting will allow you to access these underground areas so you can improve your drainage system.
To fix damaged sewer lines and water pipes — Because parts of sewer and water pipes run through your walls, fixing this kind of damage will require you to go through your walls. Concrete cutters will allow you access to these damaged features with a minimal amount of destruction to your walls.
To make your home look more appealing — You may want to add some extra features that will make your home more comfortable. You may want to add a new bathtub or pool in your backyard, but you will have to go through concrete surfaces (which will require concrete cutting).
