Concrete Cutting

Core drilling

Core bits or barrels are available in a wide variety of diameters, ranging from as small as 16mm to as large as 1000mm. While standard length core bits are 450mm long, with the use of non-standard length core bits (job specific manufacture), or specialist attachments / extensions, core holes can be drilled to almost any hole depth.
Core Drilling benefits:
  • Core drilling can be achieved to virtually any depth, diameter, or angle
  • It represents a method which facilitates a precise opening
  • Core drilling is very effective in limited or confined spaces
  • Structural integrity of the surrounding area remains intact
  • Coring can be operated in any direction, vertical, horizontal or even inverted allowing a penetration to be achieved to suit most applications
  • Core drilling can penetrate rebar, steel plates, or sheet metal

Road Sawing (Electric or Diesel)

Road sawing, also known as flat sawing or slab sawing, most commonly used to cut concrete surfaces such as roads, bridges, foot paths, airport runways, factory and office floors, piers, and wharves.
These walk-behind machines are extremely powerful and light weight and as such only require one person to operate them. Diesel Road saws are capable of reaching a penetration depth of 600mm deep. Electric units are the ideal solution for indoors or areas with low ventilation.
Applications include:
  • Removing damaged sections of pavements, roads, floors, etc
  • Creating or cleaning expansion joints on highways, driveways, and any other concrete or bitumen floor surface
  • Removal of concrete sections for demolition or refurbishment

Hand Held Sawing (Including ring sawing and chain sawing)

Hand held sawing which also includes ring sawing, flush cutting and chain sawing, represents a very versatile concrete cutting solution making it ideal for a large variety of sawing applications. Petrol, hydraulic and high-frequency electric options are available. They range in capability and depth of cut with high frequency saws now able to cut 320mm deep.Chain sawing can reach a depth of 600mm.
Hand held sawing including:
  • Formation of new doorways and windows
  • Expansion cuts in new slabs
  • Demolition cutting of walls and floors
  • Precision Trimming
  • Cutting in Confined Spaces
  • Internal cutting via use of electric hand held saws

Wall Sawing / Track Sawing

Wall sawing also known as track sawing is used to cut vertical and horizontal surfaces where the depth is beyond that of hand held sawing or the angle or access prevents use of a road saw.
To complete an opening created by wall sawing the corners are overcut to achieve the desired depth. Alternatively, where overcutting represents a structural or cosmetic issue, either core holes are drilled in the corner or a chain saw is ultised to complete.
Wall Sawing applications:
  • Precise cutting, capable of cutting 1 metre deep
  • Straight smooth finished opening in walls, ceilings, and floors
  • Accurately sized, fixture ready openings
  • Confined Spaces / restricted access areas

Wire Sawing

Wire sawing was first performed in European stone quarries. It has since been adapted to become a fast, safe, and cost-effective alternative to conventional concrete cuttings methods, especially where sawing very thick, deep or hard to access concrete structures, wire sawing is the perfect solution. Many structures are simply too large to accommodate traditional saw cutting.
Wire Sawing applications:
  • Removal of large concrete structures such as bridges, dams, building floors or walls, plinth's, etc.
  • Mass concrete removal without breakage
  • Perform cuts in restricted locations
  • Cut through heavy rebar and embedded steel
