Wall Sawing

Wall sawing utilizes circular diamond blades mounted on a rigid track system to make vertical or horizontal cuts in concrete or masonry walls. Wall sawing is typically used to cut doorway, windows and HVAC openings. This method of cutting can be used for up to 24" thick walls or floors, or up to 48" if both sides are accessible.

      Core Drilling

When a round hole is what you require, core drilling is the method of choice. We core drill from 1/2" to 42" diameter holes to virtually any depth. Typical applications include HVAC openings, plumbing lines, floor drains, anchor holes and electrical and fiber optic runs. Line drilling or coring a series of overlapping holes is another way to produce openings to any size and depth when other methods can't be used.

      Slab/Flat Sawing

Slab or Flat sawing is accomplished with a diamond blade mounted on an Electric or Gas powered saw to cut straight vertical cuts in concrete slabs, floors, roadways and bridge decks. Smaller 400 Cycle electric saws used for interior cutting and trenching, while larger gas saws are generally used for exterior and road work.

Grinding uneven or rough surfaces with an electric floor grinder will leave you with a smooth surface on sidewalks and concrete floors that have heaved and become uneven over time.
      Wire Sawing

Wire Sawing is another cutting technique used typically when size, depth and accessibility of the cut make more conventional concrete cutting methods unsuitable. The wire saw pulls a continuous loop of diamond beaded wire through guide pulleys around the aggregate to be cut. Constant pressure is produced as the drive wheel is slowly moved away from the cut causing the wire to cut into the piece as it spins around. Large expansive areas of concrete can be cut using this method.
