introductionThe DSA is the only organisation that represents the interests of companies involved in the drilling and sawing industry and is committed to improving standards within the industry by establishing better codes of safe working practice, education and training.

mission statementThe DSA’s mission is to promote the work of professional drilling and sawing contractors by highlighting the many advantages of cutting concrete with diamond tools, which include precision cutting within the shortest time scale, reduced noise, dust and debris and maintenance of structural integrity.

DSA members benefit from approved operator training courses and the adoption of national safety standards and working codes of practices, as well as affiliation with other recognised construction industry national associations. The DSA also provides a forum for members to meet within an organised framework to discuss and share their ideas on new technologies and the future development of the industry as a whole.

qualityQuality lies at the heart of the DSA’s

philosophy and members exercise the highest standards of business practice and

workmanship at all times.DSA membership is not automatic, and

applicants are subject to strict vetting procedures.

Not only are members vetted on application, they are continually monitored to meet the

high standards demanded. Vetting comprises of a detailed documentary and

Financial review. On being accepted, members agree to abide by the Code of Practice and conditions of membership

environmentalcommitment

Sustainability and environmental impact are major considerations when specifying, manufacturing and installing products in the workplace. DSA requires its members to confirm their commitment to protecting the environment, and is proactive in providing information and guidance on how best to achieve this. Its supplier members in particular are leading the way in seeking techniques and developing systems that provide high environmental and social value.

Drilling and Sawing Professionals

Today architects, engineers, general con-

tractors and government officials in the

construction and renovation industry can take

advantage of the advances in technology by

employing a specialized drilling and sawing

contractor who utilizes diamond cutting

techniques to ensure the success of any

project.

The specialty contractors who perform the

concrete drilling and sawing services are

experts in their field. Concrete cutting con-

tractors are professionals who can recommend

the best techniques and equipment for the

most cost-effective cutting, and are better

prepared to bring projects in on time and

within budget. In addition, they have the

training and experience to select the best

sawing and drilling procedures to employ at

any stage of a project.

Concrete Cutting Advantage

Knowledgeable contractors recommend and

use diamond cutting systems because they

can provide significant cost advantages over

conventional concrete removal methods.

These advantages vary depending on the

project, but include reduced downtime,

precision cutting, maintenance of structural

integrity, reduced noise, dust and debris,

limited-access cutting, and the ability to cut

heavily reinforced concrete. These advantages

have revolutionized the concrete cutting

industry. The table above details the specific

advantages over conventional concrete

removal systems.

Diamond cutting systems Conventional removal systems

Time• Fast • Slow, methodical• Fewer operators • Labour-intensive• Preliminary work possible • Preliminary work not possible• Cuts rebar and other metals • Extra metal cutting equipment required

Dimensional tolerance• Precise cuts • Uncontrolled openings• Limited patchwork required • Extensive patchwork required

Structural integrity• Vibration free • High impact vibration causes

microfractures of concrete• Ability to remove large amounts of concrete • Potential damage to remaining structures

while maintaining structural integrity or nearby equipment

Noise, dust, debris• Non-disruptive to surrounding operations • Disruptive• Relatively quiet • Loud• Pieces cut to size • Creates rubble• Dust free • Extremely dusty• Large bulk removal capacity • Time-consuming clean-up

Limited access• Remote operations possible • Inflexible equipment• Cuts in close spaces • Restricted movement• Underwater operations possible • Underwater operations difficult

or impossible• Easily cuts around existing pipes, existing • Difficult to work around piping and

fixtures and equipment electrical equipment

FOR CONCRETE DRILLING & SAWING TAKE THE PROFESSIONAL ADVANTAGE

FloorSawingFloor sawing is the most commonly useddiamond cutting method. It is typically usedto cut horizontal flat surfaces such as floors,bridge decks, and pavement. Also called slabsaws, floor saws feature a diamond bladethat is mounted on a walk-behind machinerequiring only one operator. Floor saws aretypically used to provide expansion joints,remove damaged pavement sections, cleanand repair random cracks and removeconcrete sections for demolition purposes.

WireSawingWire sawing is a technique that originated inquarries to extract stone. It has proven to bean ideal choice for the removal of thicksections of concrete. A multi-strand cablefitted with diamond beads is threadedthrough a series of pulleys and is pulledcontinuously through the concrete. Sincevirtually no concrete structure or cross-sectionis too large to cut, wire saws are used wheneverother cutting methods are impractical.The only restriction is the lifting and removalspecifications of the job.Wire sawing is ideal for removing largesections of heavily reinforced concrete, suchas piers, towers and bridge sections, and forcutting concrete in areas where work space isrestricted. So-called circle saws are used forcutting larger diameter holes for spiral staircases ect.

Techniques

Track SawingTrack sawing employs a circular blade on atrack-mounted machine. The track is attachedto vertical walls or steep inclines or floors thatwill not permit the use of floor saws. Wall ortrack sawing is typically specified to cutprecise dimensional door, vent and windowopenings. Straight as well as bevel cuts arepossible with the wall saw. The wall saw isalso an excellent choice for creating preciseopenings in any concrete structure.

CoreDrilling

Core drilling techniques are used when precise,circular cuts are needed. Holes of almost

any diameter are easily drilled to makeopenings for plumbing, electrical and HVACinstallations. Core drilling is also commonly

used to create holes for routing cables orplacing anchoring bolts, installing load carrying

devices or dowel bars, or for concretesample analysis.

Hand Sawing

Hand sawing refers to the lighter duty useof diamond blades in hand-held power sawsand chain type saws. Hand sawing provides

portability, speed and accessibility at constructionand demolition sites.

Typical applications include sawing concretepipes to length, creating smaller openings

in masonry, eliminating overcuts associatedwith other types of sawing, and precision

trimming.

Techniques

BurstingHydraulic Bursting is one of the safest and most efficient methods of removing reinforced or mass concrete, brickwork, or natural stone. Hydraulic Burster’s are placed in pre-drilled holes and expanded to induce controlled cracking of the material. Thus reducing it to manageable sections for removal. What’s more, theequipment can be used in confined spaces without risk. This technology is used to remove heavily reinforced concrete up to 5 m thick in structures such as dams,bridges, and nuclear power stations where a precise, controlled system of removal was required.

Techniques

CrushingThe crunchers are basically either a C shape or a crabs claw where the claws compress together to crush the material. It is powered by hydraulics and is driven by either an electric or diesel/petrol engine. The C shaped type has a piston that closes to crush the material. The limitations of this method are that the jaws are heavy and require a counter balancer to take much of the weight. It is alsorestricted to material under 350mm in thickness. It requires a fully boardedscaffolding below the floor area being worked upon. The advantages are small resulting rubble, no vibration, almost no noise and no water.

Remote ContolledCrushing & Bursting

Techniques

The remotely operated demolition machines are the very latest in controlled demolition,

featuring high power, low weight and functional design. They are highly powerful,

stable machines with long reach the ideal solution to many of the environmental

problems facing demolition today. These electrically powered hydraulic power packs

are remotely controlled and immensely powerful. They produce no harmful fumes

and can alleviate hand-arm vibration problems, traditionally associated with

manual work in confined spaces.
