National Concrete Cutting Co. » Services.

Core Drilling

Core drilling techniques are used when precise, circular cuts are needed. Holes of any diameter up to 48 inches can be drilled to make openings for plumbing, electrical, material testing, manhole taps, and HVAC installations. Core drilling is also commonly used to create holes for routing cables or placing anchoring bolts, as well as thick concrete demolition. Other times they are used to install load-carrying devices such as dowel bars.

Concrete core drill bits can range in diameter from 1/2 inch to 48 inches, with larger sizes available for special projects. Drilling depths are virtually unlimited with the use of extensions.

Wall Sawing

Wall sawing employs a circular blade on a track-mounted machine. The track is attached to horizontal walls or steep inclines that will not permit the use of flat saws. Wall saws make clean, precise cuts in reinforced concrete and masonry construction without the structural damage normally associated with jack hammering. Wall sawing is typically specified to cut precise openings in new construction or in structures being remodeled, such as doors, vent and window openings.

Wall sawing can be performed in several dimensions, commonly up to 30 inches deep, in any material. Cutting can be performed from both sides of a wall, giving a total depth of sixty inches.

Flat Sawing

Flat sawing is the most commonly used diamond cutting method. It is typically used to cut horizontal flat surfaces such as floors, bridge decks, and pavement. Also called slab saws, flat saws feature a diamond blade that is mounted on a walk-behind machine requiring only one operator. Cutting up to 30 inches in depth, flat saws are typically used to provide expansion joints, remove damaged pavement sections, clean and prepare random cracks for repair, and remove concrete sections for demolition purposes.

Concrete Grinding

Concrete grinding is a method of repairing uneven concrete surfaces by using walk-behind wet grinders to flatten the concrete. National Concrete Cutting uses a wet grinding approach, thereby avoiding the possibility of excessive dust, a toxic and invasive result of dry grinding. After grinding, vacuums are used to pick up and remove the resulting slurry.

Concrete grinding is a fast and less expensive method used to repair concrete surfaces as compared to concrete replacement.

Our services can, in most instances, blend away any rough or level problems in any concrete surface.

Safety Grooving

There are several ways our services can improve traction on concrete. Slippery conditions arise when debris, dirt, or water is on the surface with nowhere to go. Safety groves, created by concrete saws, allow water and dirt a location to deposit instead of remaining atop the concrete surface. This allows for improved traction on inclined surfaces, ramps, and sidewalks.

Wherever fall protection is a concern, safety grooving is the answer.

Different applications require different patterns and our retrofitted flat saw can achieve a variety of patterns.

Ground Penetrating Radar (GPR)

This method is a quick, safe, and effective way to locate buried obstructions such as rebar, post-tension cables, PVC pipes, and conduits in concrete, prior to cutting or coring. GPR is faster and safer than radiography and only single-sided access is needed.

GPR is the latest application of subsurface radar to non-destructively inspect concrete structures.

Demolition

We also offer demolition and removal services. Our trained and experienced work force takes their quality cutting workmanship one step further. To accomplish our wrecking and deconstruction services safely and efficiently, we utilize OSHA trained personnel as well as our extensive fleet of equipment including excavators, skid steers, front-end loaders, dozers, cranes, concrete crushing units, roll-off trucks and trailers.
