Ring Sawing Services: What Is Ring Sawing & Why Use a Professional Contractor? 

 

Ring sawing is one of the most precise and versatile concrete cutting techniques available to the construction industry. Whether you're working on a commercial refurbishment in London, a structural alteration in Kent, or a drainage installation in Surrey, ring sawing delivers clean, accurate results that other methods simply can't match. 

In this guide, we explain what ring sawing is, how it works, the jobs it's best suited to, and — critically — why hiring a specialist contractor like Diamond Drilling UK Ltd is the only way to get the job done safely, cleanly, and correctly first time. 

 

What Is Ring Sawing? 

Ring sawing — also known as ring saw cutting — uses a circular diamond-tipped blade mounted on a specially designed ring saw unit to cut through hard construction materials including concrete, reinforced concrete, brick, block, and stone. 

Unlike a conventional angle grinder or standard disc cutter, a ring saw features a blade that is driven from its outer ring rather than a central spindle. This design allows the blade to cut significantly deeper than a standard circular saw of the same diameter, making it ideal for applications where depth and precision matter. 

Key Technical Characteristics: 

• Capable of cutting to depths not achievable with standard disc cutters 

• Diamond-tipped blades suited to reinforced concrete, masonry, and hard aggregate 

• Wet-cutting operation to control dust and extend blade life 

• Can be used in confined spaces and awkward angles 

• Suitable for both horizontal and vertical cutting 

How Does Ring Sawing Work? 

The ring saw unit is set up against the surface to be cut. Water is fed continuously to the blade during operation — this performs two critical functions: it suppresses the silica dust generated by cutting, and it cools the diamond segments to maximise blade life and cutting efficiency. 

The operator guides the blade through the material along a pre-marked cut line. Ring saws are hydraulically powered — the blade is driven by a hydraulic power pack, which is itself powered by either a three-phase electrical supply or a petrol/combustion engine. This means ring sawing can be carried out on fully serviced sites with mains power, or on remote sites with no electrical supply. Our teams operate both configurations, selecting the right set-up for your site conditions. 

For particularly demanding cuts, ring saws can be track-mounted to guide them along a fixed path, ensuring perfectly straight, repeatable cuts even in difficult conditions. 

 

What Jobs Is Ring Sawing Used For? 

Ring sawing is a go-to technique across a wide range of construction, civil engineering, and renovation projects. Common applications include: 

Structural Openings 

• Cutting new door and window openings through concrete or block walls 

• Creating apertures for service penetrations and utility runs 

• Opening up structural slabs for staircases, lifts, and access hatches 

 

Renovation & Refurbishment 

• Removing sections of reinforced concrete floors or walls 

• Cutting precise openings in listed buildings where minimal disruption is essential 

• Alterations to existing buildings without the need for full demolition 

 

Civil & Infrastructure Works 

• Highway and road cutting for utility installation 

• Drainage works requiring precise channel cutting 

• Cutting through bridge decks, retaining walls, and tunnels 

 

Electrical, Mechanical & Plumbing (EMP) Works 

• Creating chase cuts and service runs through concrete and masonry 

• Cutting for pipe installation, conduit, and cable management 

Why You Must Use a Professional Ring Sawing Contractor 

Ring sawing looks deceptively straightforward. In reality, it is a high-risk, high-skill operation. Attempting to carry it out without the right equipment, training, and experience can result in serious injury, structural damage, project delays, and significant extra cost. 

Here is why instructing a professional specialist contractor is non-negotiable: 

 

1. Safety — Protecting Your Workers and Your Site 

• Concrete cutting generates fine respirable silica dust — one of the leading occupational health hazards in construction. Without proper wet-cutting technique and dust suppression, workers and bystanders risk long-term lung damage including silicosis. 

• Ring saw blades operate at extremely high speeds and exert tremendous force. An incorrectly mounted or over-stressed blade can shatter catastrophically. 

• A professional contractor will carry out a full method statement and risk assessment (RAMS) before any cut is made, ensuring the work is carried out safely and in compliance with CDM Regulations. 

 

2. Structural Integrity — Protecting Your Building 

• Cutting through reinforced concrete without understanding the structural layout risks severing load-bearing rebar, compromising structural integrity and potentially causing collapse. 

• A specialist diamond cutting contractor will work from structural drawings, liaise with engineers where required, and cut only within agreed tolerances. 

• Damage caused by an unqualified cutter can run into tens of thousands of pounds to remediate — far outweighing the cost of hiring a professional in the first place. 

 

3. Precision — Getting It Right First Time 

• Professional operators use track-mounted systems and laser-guided set-up to ensure cuts are perfectly straight, square, and to the correct depth. 

• Precise cuts mean less remedial work, cleaner finishes, and a faster overall programme. 

• Professionals understand how to read a structure and anticipate challenges — voids, aggregates, varying reinforcement — that an inexperienced operative won't spot until it's too late. 

 

4. Compliance & Insurance 

• Professional diamond drilling contractors carry full public liability and employer's liability insurance. 

• They operate in compliance with COSHH, CDM 2015, and HSE guidance on dust suppression and silica management. 

• Using an unqualified contractor may invalidate your site insurance or expose you to enforcement action. 

 

5. The Right Equipment for the Job 

• Industrial ring saws are specialist, expensive pieces of equipment. Hiring a professional means access to the correct machine for the job — sized and powered appropriately — without capital outlay. 

• Equipment is maintained, calibrated, and operated by trained specialists. Blade selection, water flow, power supply, and operating speed are all optimised for the material being cut.

Frequently Asked Questions About Ring Sawing 

How deep can a ring saw cut? 

Professional ring saws such as those in our fleet can achieve cutting depths that significantly exceed standard disc cutters of a comparable blade size. For particularly deep cuts, multiple passes or alternative methods such as wire sawing may be combined. Our team will advise on the right approach for your specific requirements. 

Is ring sawing suitable for reinforced concrete? 

Yes. Diamond-tipped ring saw blades are specifically designed to cut through reinforced concrete, including heavy rebar. Our operatives are experienced in managing the additional demands of cutting through reinforcement. 

How messy is ring sawing? 

Ring sawing is a wet-cutting process. Water is continuously applied during cutting, which suppresses dust and controls the slurry produced. Our teams manage slurry carefully on site, and where required we can deploy containment systems to protect sensitive environments. 

Do you provide RAMS? 

Yes. Method statements and risk assessments are provided for all our projects as standard. We take site safety seriously and our paperwork is always in order before any works begin. 

Can you cut at height or in confined spaces? 

Yes. Ring sawing can be carried out on scaffolding, at height, and in confined spaces. Our equipment and training allows us to work safely in challenging environments.
