Cutting-edge technology and superior customer service
Founded in 1961, Concrete Coring Co.‒ Los Angeles performs any application that involves drilling or cutting concrete: core drilling, flat sawing, wall sawing, hand sawing, grinding, grooving, wire sawing and demolition. The company specializes in large and deep coring, and deep wall, wire and flat sawing. The 50-year-old company has grown from a small family business to employing 37 and operating 20 trucks, and has partners in most states to take on the largest jobs.

"I originally got involved with the company when it was very much a family business,” says Dennis Richens, president of Concrete Coring and Southern California Contractors Association board member. “To a certain extent it still is, though it has grown into a modern, high-technology organization. Back then, we knew we were advanced compared with the competition, now the gap is even wider, though we still have the same family values with service as our core value."

Concrete cutting is a process of controlled sawing, drilling and removal of concrete performed by skilled operators using special saws that use diamond impregnated blades. Unlike the old-fashioned "jack hammer" method, modern concrete cutting leaves a smooth attractive finish and utilizes water to minimize dust and mess.

Core drilling
Concrete core drilling is the process of drilling perfectly circular holes through concrete walls, floors and almost any kind of concrete structure.

“Concrete core drills, also known as core rigs, can be operated without any orientation restriction,” says Richens. “Drilling can be vertical, horizontal and even upside down through ceilings. Our drill bits consist of a steel tube with diamond segments brazed or laser-welded on the drill end.”

Although concrete core drilling has little to no restrictions, it is most commonly used for what's known as utility penetrations ‒ electrical, plumbing, etc. Concrete coring also prepares concrete buildings for sprinkler systems, heating, ventilating, and air conditioning ducts, as well as fiber optics, phone lines, computer lines, and much more.

Core drilling operations are used abundantly in underground utilities ‒ most often, manhole taps, underground vault taps, and anywhere sewer, water, steam, air or communication lines pass through a concrete or brick structure. Core drilling is dust-free, quiet and capable of slicing through steel reinforcing rods with little to no difficulty. Unlike rotary percussion tools, there are no vibrations. Drills are attached to a secured stand on a wall or floor with a concrete anchor and a bolt. There are also core drills that vacuum-attach to a floor.

Concrete Coring also uses many different types of hand-held core drills with bits ranging from 1⁄2 to 72 inches in diameter and drilling depths nearly unlimited due to the use of extensions. A solid core of concrete is removed from the hole after the drilling is complete

Diamond wall sawing
“Our capabilities don’t end there,” says Richens. “Diamond wall sawing is another important capability. This is usually used when a hotel or large building needs to add a wing or when a large building needs a major demolition or addition. With the use of diamond tips, this is a relatively clean and non-percussive way of accomplishing sawing operations.

Depending upon the situation, diamond-tipped blades can be placed in different power units for efficient wall sawing. This can be done with diamond-covered wire or blades in surfaces that are difficult to saw, such as concrete, reinforced concrete, brick and all types of stone.

“Cutting openings in concrete walls with diamond tools,” says Richens, “causes no damage to the structure, requires no patching and is dust-free.” A track-mounted wall saw is a quick, clean method of creating larger openings. Wall or track saws use a circular diamond-tipped blade atop a track-mounted machine. The track is connected to horizontal walls or steep tilts that will not allow the use of floor saws.

Wall sawing is usually specified to cut precise functional holes such as dimensional doors, vents and window openings. According to Richens, it's the optimal choice for creating perfectly measured openings in any concrete structure.

Diamond wire sawing
With the recent motorized system of guided wheels improving efficiency and power, diamond wire sawing has become increasingly more popular. The precise quality of cuts from diamond wire sawing makes it the method of choice for many demolition or remodeling projects.

“Wire sawing is perfect for getting rid of large sections of heavily reinforced concrete, such as piers, towers and bridge sections,” says Richens. “Also it’s ideal for cutting concrete in areas where space is restricted.”

Wire saws are diamond-covered wire fed through a series of pulleys to produce a cutting facility to handle any depth or shape of concrete structure with no vibration, noise or dust. This is primarily used when other cutting methods are impractical. Wire sawing takes less time and requires fewer operators than conventional methods.

Between a rock and a hard place
Although called Concrete Coring, the company is also well equipped to deal with rock and stone. Often companies find themselves literally between a rock and a hard place to install new telephone poles, pour foundations or add a basement.

“This is easily done with our drilling capabilities,” says Richens. “We can cut right through any rocks and remove them. We can cut through any stone to make way for any type of construction. We never need to go around an obstacle.”

Concrete Coring is growing quickly to accommodate new technologies.

“For years, we’ve been doing everything we can to provide the highest quality customer service,” says Richens. “Our operators are highly skilled in all aspects of sawing and drilling concrete, and our customers have come to expect only the best from us. We will do anything and everything our customers require and hopefully even go a step beyond their expectations, making sure every aspect of every job is done as perfectly as is feasible. Our technology is the best in the business, which enables us to accomplish any job, no matter how big or small.”
