Con-Cor began cutting concrete in the early 1960, using core drills, and 3” diameter diamond tipped bits. In the beginning all openings were cut with a core drill. Some of the first openings cut for stairwells were line cored. Since the early 60’s we have expanded both our technology and the capacities.

We currently are capable of drilling hole from 1/8” in tile to diameter to a 57” dia. Sewer holes for a water treatment plant. There is no limit to the depth of a hole. Con-Cor has drilled holes over 30 feet deep.

Con-Cor operators use core drills, wet or dry, to cut through any masonry, concrete or asphalt material.

Con-Cor began using Pavement Saws in the early 1970’s. Pavement Saws were used for sawing small jobs in the beginning, but flat sawing is now widely used in the repair and rehabilitation of concrete floors, asphalt parking lots, and roadways.

With our 10 hp electric saw, for hospital or office work, to our 72 hp diesel saws, for Airport Runway work, Con-Cor Co’s Pavement Saws spend more time on the road than most cars.

Wall sawing started in the mid 1970’s. This is the most labor intensive of all concrete cutting. Con-Cor’s operators have cut through walls as thick as 30” from one side, and 60” with access to both sides. Chain Saws are used to square cut the corners so there is no overcut.

Wire Sawing is one of the latest concrete cutting techniques. There are no size or shape limitations to wire sawing. If a wire can be wrapped around the concrete, it can be cut.

This is the most rapidly growing portion of our business. Con-Cor operators have cut decorative designs into concrete, cut green concrete joints, slots for traffic and high speed door loops, and curb cuts.

We can also do floor grinding, bridge deck grooving, and Removal of the concrete we cut. Chain Sawing of concrete walls and floors has taken the construction industry by storm.

Con-Cor was the first sawing and drilling company to use chainsaws for square corners. Con-Cor also will pour back floor trenches, and pour concrete driveways and sidewalks.
