Access Drilling's Wire Sawing solution is an extremely versatile method of cutting reinforced concrete, brickwork or masonary. It is deployed where other methods of drilling or sawing are not practical such as cutting out mass filled concrete, removing plinths, bridges, staircases, plus it can also be used to flush cut to existing walls.

Our wire saw is hydraulic whose power is supplied via either a petrol-powered or a 3-Phase hydraulic power pack. This saw can therefore be used indoors as well as outdoors and because it is a modular system which makes it very light and manageable it is ideal for working in restricted areas. Our wire saw works via a continuous diamond coated wire running through a series of pulleys which are threaded around the girth of the concrete to be removed or cut. Once the machine is set up the tension on the wire remains constant, and as the cutting progresses, any slack is taken up and stored on the pulley system on the machine until the cut is complete. Our method of wire saw cutting has a virtually limitless depth or size of cut. 

The Access wire saw is semi-automated, operated from a safe distance away from the work area - therefore there is no contact between the machine and the operator during the cutting process, reducing fatigue, eliminating HAV and most importantly the risk of injury.

Example of  Work carried out using our Wire Saw:

Removing Reinforced concrete hopper walls in water tanks
There were 4 water tanks with 3 hoppers in each, through which an 800mm pipe was to be laid below the floor level of all 4 tanks where the hoppers were. Therefore the angle walls of each hopper were to be removed, as the hopper walls were 300mm thick at the top increasing to 1.8 Metres at the invert level the only feasible method of performing the work was to wire saw it. The walls were on a 60 degree angle so our stitch drilling solution was not an option as the work was to be carried out during a shut down so it had to be done quickly.
  
Holes were drilled through the bottom corner of each hopper wall, through which the wire is then threaded and attached to the machine and pulleys. We made 3 cuts to each hopper which then left them free to be lifted out using a crane, with each piece weighing around 2.25 Tonnes  but leaving a neat flush cut ready for installing the pipework.
 
All the work was carried out as scheduled and finished on time!
