Core drilling

Diamond core drilling or “coring” is the process of drilling perfectly round holes through concrete, masonry, brick, stone, and asphalt structures such as walls, floors and ceilings.

Diamond core drills can be operated in any orientation, vertical, horizontal and even upside down.

Diamond core drilling is the most frequently used demolition method in day to day use. The demands made in this area are numerous, from series drilling with hundreds of holes to single, metre deep holes with precisely defined angular positions, or drill holes in a base structure containing extremely high levels of reinforcement. Electric and hydraulic core drill motors are used to drill holes of diameter 6mm to diameters in excess of 1 metre.

We have a range of Core Drills available for all of your Concrete Drilling needs including Electric and Hydraulic. We also have an Inverted Core Drill which allows us to drill upside-down.

Holes of any size depth can be achieved through this process from as small as 6mm up to 1200mm diameter +.

Core Drilling is used when a job calls for the drilling of circular holes in reinforced concrete, precast concrete, asphalt, brick, sandstone and other structural materials.

We offer high-precision core drilling services for arrange of materials including:

  • Drilling holes from 6mm-to over a metre in diameter
  • Up to any depth
  • Hand held, bolt down and vacuum suction options available
  • Safe servicing for challenging situations
  • Ensuring the best quality dust-free results.
  • Guaranteeing a safe and clean environment from beginning to end

 

 

 

 

 

 

 

Road Saw

Road Saw- Road sawing is an effective and economical method for the cutting of horizontal concrete structures such as concrete slabs, car parks, roads, pavements, asphalt, suspended slabs, driveways or for the formation of expansion joints and chases.

We use road saws that are self-propelled by petrol, diesel or 3-phase electric motors that are capable of cutting depths of up to 500mm using diamond blades.

Electric road saws are used in poorly ventilated or confined space work areas. For example trenching required by plumbers for shop fitouts and any indoor cutting activities.

Road sawing, also known as slab sawing or floor sawing, is used to cut horizontal flat surfaces such as concrete floors, tiles, pavers, brick floor, cobble stone, bridge decks, roadways and pavement.

Road sawing is typically used for:

  • Control joint cutting in newly poured concrete
  • Removal of damaged concrete and asphalt pavement sections
  • Exterior utility installation, upgrades and repairs
  • Demolition cutting for selective slab removal
  • Curb, gutter and sidewalk cuts for new driveway approaches
  • Bridge deck repair
  • Highway and runway repair and upgrades

Other applications for the Road Saw are;

  • roadworks
  • trenches for plumbing and drainage
  • driveway and kerb removal
  • slab removal
  • modifications to existing structures

Some of the areas we offer road and highway road base cutting and sawing are:

Moree, Tamworth, Armidale, Glen Innes, Grafton, Coffs Harbour, Port Macquarie, Newcastle, Ballina and all the area’s in between.

Specialising in these regions North Coast, New England, Central west, North West and all over New South Wales.

Some of the road sawing and cutting projects we have undertaken are:

Joint sealing

Joint sealing is used to prevent air, water, and other environmental elements from entering or exiting a structure while permitting limited movement.

Joint sealing is done to prevent the entry of surface water below the concrete slabs, as water infiltration will dramatically shorten the durability of concrete.

Sealant is used to seal joints to stop chipping and cracking of concrete where cars and trucks are constantly driving

Joint sealant is used for:

  • Sealing of expansion joints in concrete.
  • Silicone sealant is RTA approved 100% movement
  • Roadways to Highways
  • Airports, car parks, driveways, factories, workshop slabs
  • Water spillways to dams
  • Joint Sealing is used to help keep the integrity of the expansion or construction joints by sealing the joints with a wide range of sealants specified.
  • Joint sealing has many applications and is used on highways, airport aprons, footpaths, driveways, hard stands and wherever two concrete slabs meet.
  • Most joints require widening from 6mm to 40mm prior to application.
  • We will install all types of sealants to the manufacturers’ specifications and we have a vast experience in many different types of joint sealing applications.

Joint Sealing or Caulking:

Joint sealing is where we seal the joints in concrete pavements to prevent the entry of surface water below the concrete slabs, into the substructure of the pavement. Water infiltration will dramatically shorten the durability of concrete. Water that penetrates to the sub base of the pavement will allow it to soften and become unstable. Joint sealing of a concrete slab also prevents the joints filling with non-compressible matter which will prevent expansion joints from allowing movement, thus shifting stresses to other points in the slab and eventually leading to irregular cracking.

Unsealed joints may allow a concrete slab to sink and crack. If utilised early enough joint sealing can defer and even eliminate the need for more expensive maintenance such as Slab Jacking/Stabilising (Mud Jacking, Lifting, and Pressure Grouting) or in worst case, the much more expensive cost of complete reconstruction of the concrete slabs.

The use of joint sealing on a concrete pavement prior to an asphalt overlay slows and greatly reduces reflective cracking on the new pavement layer.

What types of joints are suitable for sealing?

Longitudinal joints, (construction joints, control joints, or expansion joints)

Transverse joints, (construction joints, control joints, or expansion joints)

Joint seal walls/ brick work + Tilt Panel etc

Grinding & grooving

Grinding and Grooving or scarifying is capable of levelling footpath irregularities, uneven joints, bumps and repairing of uneven surfaces such as trip hazards in footpaths and walkways.

We have a variety of grinding and grooving equipment for planning and levelling of concrete and asphalt. We can also remove Traffic Lines and old coatings. We also cut Anti-slip grooves on any concrete surface.

Grinding and Grooving is also used for cleaning factory floors, roughening ramps and walks, preparing surfaces for new coatings, grinding away uneven surfaces on concrete and asphalt.

Track saw

Track mounted wall sawing is an efficient method of achieving clean and controlled demolition of building structures with a cutting capability of up to 750mm thickness either horizontally, vertically or even inverted. The track saw is operated by remote control away from the surface being worked upon. The cutting is carried out by making a series of passes along the length being cut at progressive depths until the desired cut is achieved.

Track mounted wall sawing system cuts at a depth of 725 mm and runs off 3 phase power. This method is ideal for confined spaces and demolition work as the Track saw is remotely operated. Its powerful motor makes it perfect for deep cutting of heavily reinforced concrete walls. All cutting is fume free and being a modular system it can be used in hard to access areas that other saws cannot be used.

Track saw can cut precisely plumb, level or bevelled edges in shear walls, masonry walls, pre-cast concrete, reinforced concrete and metal.

Track Sawing is used for :

  • Bank Vaults, Lift Shafts, Water Tanks
  • Abutments
  • For putting in openings and breaking through walls
  • Winged walls on bridges
  • Brick Work
  • Thick walls where they can only be cut from one side
  • For wall thicknesses of 725mm

 

 

Hand & Ring Saw

Hand & Ring Sawing

Hand and ring sawing can be used where there is insufficient space for a road saw and on applications. such as: cutting smaller openings ie windows and door openings; pipe cutting and installation work as well as kerbs and pathways.We use petrol, electric, high frequency and hydraulic hand saws for cutting depths in walls and floors by hand up to 200mm deep.Ring saws include petrol and hydraulic which are used to cut walls and floors up to a depth of 400mm, a clear advantage over traditional hand sawing.

We have Petrol & Hydraulic Ring Saws. They are hand held machines, which are used for cutting floors in areas that are not accessible for a floor saw.

Ring Sawing is used for cuts over 150mm to 400mm deep, which is extremely useful for cutting block and concrete walls in confined spaces which are more than 150mm in depth.

Ring sawing is used for any concrete– some examples are:

  • Concrete Pipes
  • Double Brick and block walls
  • Door and window openings
  • Ventilation cut outs
  • Cutting in confined spaces
  • The Hydraulic Ring Saws that we operate are either 18 hp Petrol or 3 phase Electric, enabling a maximum cutting depth of 400mm. These ring saws are extremely safe and very useful when it comes to situations where the cutting job has to be done in a confined space. The maximum depth for ring sawing is 400mm.

Dragon Sawing is available in hydraulic only and can also cut to a depth of 400mm.

The Petrol Ring Saw is used after the hand saw to depth of 260mm and are extremely useful for cutting door openings or where concrete or brick is thicker than 150mm

Our results are second to none and our team is professional and prompt. Call us today to discuss your ring sawing requirements with our experts.

 

Wire Sawing

Wire sawing is used for all demolition work that cannot be achieved by wall sawing or core drilling. This method uses continuous or loop diamond wire in virtually unlimited lengths. Wire sawing is an extremely universal process with almost unlimited application possibilities.

  • Wire Sawing:
  • Diamond wire saws are more efficient than circular saws, able to cut concrete of almost any thickness. This makes them very useful for the kind of heavy demolition found in bridges, dams and thick concrete structures. In addition, they create little dust, noise and vibration, making them ideal for demolition work within inhabited structures.

 

Rock & concrete splitting

DARDA splitting cylinders are designed to split natural rock and concrete, a function which, with the use of hydraulics, is accomplished with the utmost precision, environmental friendliness and cost effectiveness. Whereas traditional methods of rock blasting are accompanied by complex, high cost safety precautions, the safety requirements entailed by this technique are reduced to a minimum.

Recently Stocks and Hogan had a difficult job to do splitting and removing rocks beside the house where they wanted to do renovations, the rock was too close to the footings and could not be blastered or removed.

So a less non invasive method using DARDA achieved to result without damage to the existing property on the North Coast.

We offer these services and more from Newcastle through to Tweed Heads including: Coffs Harbour, Moree, Tamworth, Armidale, Glen Innes, Grafton, Newcastle, Ballina and all areas in between.

Along with rock splitting we also offer:

•Concrete Sawing
•Concrete Drilling
•Concrete Hand Sawing
•Concrete Road Sawing
•Concrete Ring Sawing
•Concrete Grinding & Grooving
•Concrete Polishing
•Joint Sealing
•Concrete Core Drilling
