We take great pride in our workmanship with customer satisfaction and professionalism being at the top of our list. We provide several different services including slab sawing, asphalt sawing, wire sawing, wall sawing, chain sawing, hand sawing, curb cutting, jack hammering, concrete slab pour backs, rubble removal, complete demo, ground penetrating radar known in the industry as “GPR” and X-raying
We serve Maryland, Northern Virginia and Washington DC (District of Columbia)
Core drilling is performed when precise, circular diameter cuts are needed. Holes up to 40″ in diameter can be drilled to virtually any depth. A core drill is a drill specifically designed to remove an annulus of material rather than an entire cylinder of the material being drilled, as a typical auger -type drill bit would. The material left inside the drill bit is referred to as the core.
Core drilling is used for plumbing, electrical, and HVAC installations. Line drilling is an effective method for removing almost any thickness of concrete where other methods cannot be applied. Core holes are drilled in a series of overlapping holes, allowing for one large segment to be removed.
Core drills are used for many applications, either where the core needs to be preserved or where drilling can be done more rapidly since much less material needs to be removed than with a standard bit.
TYPICAL APPLICATIONS INCLUDE:
Phone, electrical, cable and fiber optic opening
Handrail and anchor holes
Concrete block, solid concrete, asphalt, brick, and steel are all able to be core drilled. Floors and walls are the most common structures to core but requests come in for other structures as well. Core drilling is typically completed using a wet process. If water is an issue, smaller holes can be completed using a dry coring process. If a special angle is required, our operators can setup their core rigs to accurately achieve multiple angles.
Flat sawing is the most identified diamond cutting method. Flat sawing features a diamond blade that is mounted on a walk behind machine and requires one operator. It is generally used to cut on horizontal surfaces such as floors, bridge decks, expansion joints and pavement. Flat sawing can be performed with a gas or electric, exhaust-free unit. Generally cuts can be made up to 24″ deep. However, we do offer specialized cuts up to 27″ deep.
Flat sawing is an efficient means of cutting any aggregate. It is quick and precise, allowing other contracting work to be performed virtually uninterrupted.
TYPICAL APPLICATIONS INCLUDE:
Cutting reinforced concrete floors
Cutting expansion and control joints
Remove damaged pavement/concrete sections
Clean and prepare cracks for repair
We will saw the perimeter of areas you are replacing to provide a clean edge to improve the appearance of your repair and remove the asphalt. We can also saw through multiple layers, simultaneously. Asphalt layered over brick and/or concrete is a very common installation for older streets and lots. We have had cases where even sand is an intermediate layer.
Wall sawing employs a circular, diamond blade on a track-mounted system that can be used for vertical and horizontal cuts. This set-up can also be used on steep inclined surfaces where a slab saw cannot be used safely. Wall sawing is typically specified to cut precise openings for doorways, ventilation units and windows. Specialized applications such as finishing roughed-in walls can also be performed.
Wall sawing can be performed up to 24″ deep indoors or outside. Cutting can also be performed from both sides of the wall, giving a total depth of up to 48″. The wall sawing unit is highly portable and easily set-up for our trained operators. The applications for this type of sawing are endless.
TYPICAL APPLICATIONS INCLUDE:
Straight, smooth finished openings in walls, ceilings, and floors
Accurately sized, fixture ready openings
One issue in with round blades is that the corner cuts cannot be completed without over cutting. If the opening is going to be trimmed out or the aesthetics of the cut are not important then overcuts won’t be an issue. With an opening that cannot have over cuts, the chainsaw does a great job of cleaning these corners out as illustrated. This added cost is an affordable solution to the old style way of coring the corners that left scallops that needed to be chipped. Chain sawing is limited in its depth to 30”.
G.P.R. – Concrete Scanning
GROUND PENETRATING RADAR
If you are concerned the area to be cut or drilled might have utilities or reinforcing cables, Ground Penetrating Radar (GPR) is the solution. GPR can quickly and accurately locate obstructions like conduits, plumbing lines, fiber optics, duct banks or post tension cables in concrete prior to cutting or drilling. Using GPR to locate subsurface obstructions can help avoid costly repairs, downtime and injuries. Take the extra measure to ensure that there are no issues on your project.
Our specialized X-ray services are ideal for locating and identifying embedded objects in accessible concrete structures. Our trained and certified radiographers have been providing high resolution X-ray services for over 20 years in the concrete inspection industry. Our process is simple, reliable and extremely effective – we place a light film on one side of the structure and a cobalt source produces radiation for a highly readable result which is interpreted by an expert.

Complete & Partial Demo
Our demolition services include all types of concrete and asphalt cutting and removal. We specialize in selective demolition such as wall opening removal while maintaining structural integrity or excessively thick asphalt or concrete removal. We are capable of large-scale demolition including swimming pools, concrete structures, bridges, dams, and arroyos.
