Wire & Wall Sawing

Wire Sawing

How Does Wire Sawing Work? A multi-strand cable with diamond segments is threaded through a series of pulleys and is continuously pulled across and 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 placed on the size and weight of a concrete piece cut by a wire saw, is simply the lifting capacity and removal specifications of the device transporting the piece. Wire sawing professionals can set up equipment to perform two types of cut—push or pull. As the names suggest, the methods involve pushing or pulling the wire in a given direction to complete a cut by the placement of pulleys and the adjustment of wire length and tension. Electroplated lengths of diamond wire are commonly used for underwater cutting, typically 10 millimeters in diameter with 40-48 beads per meter. Earlier diamond wire designs consisted of plastic injected over springs, but today many are rubber injected over springs. Wire can be ordered to any length, making it a very versatile tool.

Wall Sawing

The term ‘Wall Sawing’ denotes the cutting of walls such as: Concrete walls, pits, or areas that cannot be cut or accessed by other conventional flat cutting equipment. The equipment consists of a hydraulic, air or electric motor on a frame that is attached to a track that has been mounted on a surface. The motor is fitted with varying sizes of blades to 48″ enabling a cutting depth of 22″. We have the capacity to run a 54″ or 60″ blade in certain conditions. Door openings and window openings required precise cutting dimensions to receive the enclosure frames. A wall saw is the precision cutting tool to perform this task.

The corners of an opening after wall sawing are not cut through unless the opening is cut past the connecting cut line; this is because of the use of round diamond blades. If over cutting the opening is not permissible, or a structural issue, a hydraulic chainsaw can be used to sweep the corners to a square cut.
