Core Drilling

Concrete core drilling or “coring” is the process of drilling perfectly round holes through concrete walls, floors and other concrete structures. Concrete core drilling is the most commonly recognized use of any diamond concrete cutting tool. Concrete core drills or “core rigs” can be operated in any orientation, vertical, horizontal and even upside down thru concrete ceilings. A concrete core drill bit consists of a steel tube with diamond segments brazed or laser welded on the drilling end. The core bits are mounted on the rotating shaft of various types of concrete core drilling machines. Most concrete core drills are connected to a stand that is secured to a wall or floor with a concrete anchor and a bolt but there are also concrete core drills that use a vacuum to attach to a floor.

Concrete core drills can be powered by electricity or hydraulic power sources. Concrete core drill bits can range in diameter from 1/2 inch to 72 inches in diameter and drilling depths are virtually unlimited with the use of extensions. A solid cylindrical slug or “core” of concrete is removed from the hole after the drilling is complete. The applications for concrete core drilling are virtually endless.

Core holes are used for “utility penetrations” such as electrical, plumbing and heating. Concrete core drilling also allows concrete structures to easily be made ready for sprinkler systems, HVAC ducts, fiber optics, phone lines, computer lines and much more. Core drilling methods are used widely in underground utilities construction, most commonly, manhole taps, underground vault taps, and wherever sewer, water, steam, air or communication lines pass through a concrete or brick structure.


Wall Sawing is the process of cutting openings such as doors or windows in concrete walls and foundations, usually no more than 16″ thick but in some cases up to 36″ thick. This is accomplished by using a saw that attaches to a track on the wall to be cut. This process utilizes a 24″ to 84″ diameter diamond blade that can cut from one side. This aspect of our business requires the most skill and cannot easily be done by your average layman. As stated, wall sawing may entail cutting openings in concrete foundations but may also include lowering a foundation elevation, entire foundation removal and also the cutting of concrete retaining walls in part or in whole. This type of concrete cutting requires skill and experience to cut perfectly smooth plumb and level openings with virtually no dust or mess. It is a rather expensive service however, it is a bargain for the work that is possible in a short amount of time.


Flat Sawing

Slab sawing, also known as flat sawing, is used to cut horizontal flat concrete surfaces such as floors, bridge decks and pavement. Slab saws feature a diamond blade that is mounted on a walk-behind machine that requires only one operator. We can cut up to 27 inches in depth but generally only 8 inches or less is necessary for most applications. Slab sawing is the perfect solution for making penetrations or openings in concrete floors to access and repair a broken water pipe or sewer line. Other typical uses for flat sawing is- sawing for new machine foundations, highway patching, plumbing trenches (we also remove and re-pour) and Runway repair. Attempting a slab saw project can be very time consuming and dangerous for your average person. We use very high powered equipment, both diesel and electric saws (indoor sawing).  Save yourself from the serious danger and aggravation by contracting the concrete cutting professionals at All-Saw.

Concrete Removal

All-Saw offers surface preparation services to remove concrete from construction site, land development site, commercial or residential locations.

Wire Sawing

This innovative technique originated in quarries to extract stone, and is ideal for cutting thick concrete. A multi-strand cable with diamond segments is threaded through a series of pulleys and is continuously pulled through the concrete. Since virtually no concrete structure or cross-section is too large to cut, wire saws are used where other cutting methods are impractical. The only restriction is the lifting and removal specifications of the job.

Wire sawing is ideal for removing large sections of heavily reinforced concrete, such as piers, towers and bridge sections, and cutting concrete in areas where work space is restricted.
