CORE DRILLING
Diamond core drilling techniques are used when a precise circular penetration is needed. Holes of just about any size and depth can be achieved through this process, as small as 1/2" to 60" in diameter and from 1/2" to 100" in depth. Coring can be done in slabs and walls, on any angle and even upside down through a ceiling when no access is available. Diamond core drilling can be used for many applications, including but not limited to holes for:

• Plumbing
• Electrical
• HVAC
• Telecommunication Lines
• Anchoring Bolts
• Concrete Sample Analysis

These techniques are commonly used in concrete, pre cast concrete, asphalt, brick, cinder block and tile. Core drilling machines typically run off of electric power sources but for large diameter holes hydraulic is available.

SLAB SAWING
Slab Sawing, sometimes referred to as flat or road sawing. Sawing is the most commonly used diamond cutting method. A slab saw is a walk behind machine with a blade mounted on a spindle. Common slab saw uses include cutting trenches to install plumbing and electrical pipes below grade, expansion joints, decorative sawing, or to remove damaged areas. Saws can range from five to over one hundred horse power to suit any application. This technique is commonly used in concrete, pre-cast concrete, asphalt, bridge decks, and brick pavers. Our slab saws are avaialbe in gas, propane and electric. Cutting depths vary for each saw: maximum depth is twenty-one inches.

WALL SAWING
Wall Sawing is a track mounted saw that is used to cut precise dimensions in walls and floors. Typical uses include cutting windows, doors, hvac openings, elevator and stair openings, and separation cuts for demolition contractors. Our wall saws can cut up to 24" from one side, can be set on any angle, and can cut flush to adjacent surfaces. Common applications include cutting concrete, pre cast concrete, brick, and cinder block. The wall saw is powered either by hydraulic or pneumatics depending on the applications.

HANDHELD SAWING
Handheld Sawing techniques are generally used for smaller jobs where it is faster and more cost effective than using other cutting methods. Typical applications include HVAC openings in brick and cinder block, beam pockets, and small openings in slabs and walls. Hand held saws can cut up to a six inch depth from one side, and are available in electric and hydraulic depending on the application.

RING SAWING
Ring Sawing is a hand held hydraulic saw that is capable of a cutting depth of ten inches from one side. The ring saw differs from other saws because the blade is not put on a spindle, the blade has no core (center) and it rotates on a roller system which allows a fourteen inch blade to cut a depth of ten inches.

CHAIN SAWING
Hydraulic Chain Sawing is generally used in conjunction with wall sawing. The chain saw can cut the corners without any over cuts, saving the integrity of the slab or wall that is to be left in place. Chain saws are also used to cut openings in floors or walls when it is more cost-effective then other cutting methods. Chain saws are commonly used for HVAC openings that are relatively small in outside dimension. This allows a penetration that is not possible with a blade.

STITCH DRILLING
Stitch Drilling is a common technique used when other cutting equipment can not be utilized. Stitch Drilling is often the answer when the structural integrity of the area around the opening can not be compromised, when there is tight working quarters, or a relatively thick slab or wall. Stitch Drilling is coring a series of holes around the perimeter of an opening and then chipping the excess concrete.

HORIZONTAL CURB CUTTING
Horizontal Curb Cutting is used to relocate driveways, sidewalks, and handicapped entrances. Curb cutting is accomplished by using a standard wall saw mounted to 90° plates and secured to the curb to be removed. Excavation of the back side of the curb is necessary for this method.

CONCRETE BREAKING AND REMOVAL
Cobra prides itself on being an interior removal specialist. In areas where bobcats and other machines cannot be used Cobra utilizes sawing techniques to dice up areas into manageable pieces to be removed by hand.

Concrete Breaking is offered when other cutting methods are not practical. Cobra utilizes air compressors and jack hammers to break up concrete slabs and walls. Other breaking services are available such as chipping slabs and walls to expose rebar and pipes.

BOBCAT SERVICES
Cobra offers concrete removal off-site, concrete breaking, auguring and trenching.
