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
