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:
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:
Other applications for the Road Saw are;

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:
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 or scarifying is capable of leveling footpath irregularities, uneven joints, bumps and repairing of uneven surfaces such as trip hazards in footpaths and walkways.
We have a variety of grinding equipment for planing and leveling of concrete and asphalt. We can also remove Traffic Lines and old coatings.
Grinding 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 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 :
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:
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 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.
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 Hand Sawing
•Concrete Road Sawing
•Concrete Ring Sawing
•Concrete Grinding & Grooving
•Concrete Core Drilling
