Wire Sawing

Wire sawing is a technique that originated in quarries to extract stone. It has proven to be an ideal choice for removal of thick sections of concrete.

A multi-strand cable with diamond segments is threaded through a series of pulleys and is continuously pulled through the concrete.

Since virtually no concrete structure or cross-section is too large to cut, wire saws are used where other cutting methods are impractical.

The only restriction is the lifting and removal specifications of the job. Wire sawing is ideal for removing large sections of heavily reinforced concrete, such as piers, towers and bridge sections, and cutting concrete in areas where work space is restricted. A wire saw consists of a multi-strand cable with diamond segments that are threaded through a series of pulleys attached to a drive wheel that is powered by a hydraulic power unit. The combination of the spinning wire and constant pulling force cuts a path through the concrete and steel reinforcement.

A typical wire diameter is 10 mm. Wire saws can cut in any orientation, vertical or horizontal. Because the length of wire can be made to virtually any length, the cutting depth is unlimited.
