Wall Sawing

Wall sawing employs a circular blade on a track-mounted machine. The track is attached to vertical walls or steep inclines, or floors, that will not permit the use of flat saws. Wall or track sawing is typically specified to cut precise dimensional door, vent and window openings. Straight as well as bevel cuts are possible with the wall saw. The wall saw is also an excellent choice for creating precise openings in any concrete structure.

The diamond wall saw blade consists of a circular steel core with diamond segments attached to the periphery. The blade is mounted on the spindle of the wall saw. The spindle runs along the wall saw track that is typically bolted to the cutting surface. The power source for a wall saw system is either hydraulic, air or electric. Wall saw blades can range from 18 to 72 inches (457 mm to 1.8 m) in diameter and can cut up to 33 inches (838 mm) in depth.

The use of a wall saw allowed a general contractor to safely remove a silo in the middle of existing buildings to perform a renovation of a fire brick manufacturing plant in Manistee, Michigan. A CSDA contractor was hired to remove the silo in the middle of the winter with temperatures below freezing. The 57 foot (17 m) tall reinforced concrete silo was cut with the wall saw and removed in three 19 foot (5.8 m) sections. In total, 1,025 feet (312 m) of 9 inch (229 mm) thick and 341 feet (104 m) of 12 inch (305 mm) thick reinforced concrete, weighing over 350 tons, was removed in only six weeks. The general contractor could not have performed this project without the services of a professional CSDA contractor and the use of the wall saw.

Wall saws are powered by hydraulic power units, which give the operator the ability to access any opening, outside or inside. Wall sawing creates a precise cut in walls and can also make flush cuts to other existing walls. Cut with a circular blade, the wall saw has the ability to cut up to 24' thick from one side.

Typical Applications:

Cutting precise door and window openings in concrete, granite, block or brick
Cutting up to 48" thick concrete if both sides of the walls are accessible
Cutting vents and similar type openings
Cutting vertical walls and steep inclines where slab sawing can not be done
