Floor Sawing Services in Kent

If you’re looking for floor sawing services in Kent, you want a specialist with the right diamond saws, the right cut-depth capability, the right accreditations, and the experience to handle live sites, embedded services and the interface with any follow-on work like joint sealing or slab reinstatement. Floor sawing isn’t a task for a general civils crew with a rented saw. It needs owned diesel and electric saws, blade specifications matched to the concrete strength and reinforcement density, operatives trained in NVQ Level 2 cutting and drilling, and site methodology that stands up under HSE and client scrutiny.

At Shepherd and Sons, we deliver floor sawing across Kent and the wider South East as part of our concrete cutting service, with more than 40 years of specialist experience across airfields, highways, ports and infrastructure. We’re based at Westerhill Farm just outside Maidstone, we hold SafeContractor and CHAS accreditation, and we’re members of the Extruded Sealant Association for the related joint sealing work that usually follows on from cutting. This article covers what proper floor sawing services in Kent look like, the local project types we cover, the questions to ask before appointing anyone, and how to specify the work properly.

Floor sawing (also called slab sawing) uses walk-behind saws with large diamond-tipped circular blades to cut horizontally through concrete floors, pavements and slabs. The blade grinds through the concrete, producing a clean vertical edge ready for the next phase of work. For technical background on the method itself, what is floor sawing? covers the mechanics, saw types and depth relationships.

A proper Kent floor sawing service will typically include:

Diesel and electric saws. Diesel for external highway, airfield, port and yard work. Electric for internal warehouses, food-grade sites, hospitals and any ULEZ-adjacent London work that touches Kent. Petrol as a mid-range option for smaller sites without full diesel mobilisation.

Cut depths from surface scoring to 420mm. Our standard fleet handles the vast majority of Kent slab thicknesses, including highway carriageways (200mm to 350mm), airfield pavements (300mm to 500mm), port hard standings (250mm to 400mm), and industrial floors (150mm to 250mm). For cuts beyond 420mm, wire sawing takes over.

Blade specifications matched to reinforcement. Highway concrete, airfield concrete and industrial floors all have different reinforcement densities. Blade specification is matched to the actual concrete rather than pushed through with a generic blade regardless of substrate.

Wet cutting as standard. Continuous water feed cools the diamonds, suppresses dust at source, and lifts the concrete slurry clear of the cut. Slurry containment is built into the site methodology.

Interface with follow-on work. Cutting rarely ends the scope. Slab replacement, joint sealing, service installation and reinstatement all sit downstream of the cut. A proper Kent floor sawing service will plan the cut geometry around what comes next.

Kent’s geography brings a specific mix of floor sawing work, and we’ve delivered across all four sectors we cover.

Aviation. Floor sawing at UK airports for runway joint reformation, taxiway slab replacement, apron reinstatement, and airside civil pavement work. Kent’s proximity to the London airport network (Gatwick, Heathrow, City, Luton, Stansted all within easy mobilisation range) means aviation is our largest single volume. Our sole BAA PLC contractor status since 2008 anchors this work.

Highway. M20, M2, M25, A20, A2 and A21 carriageway joint reformation, slab replacement, drainage trenching and bridge deck work for highway authorities and Tier 1 contractors. Kent’s motorway and trunk road network is one of the busiest in the UK, and floor sawing is specified regularly on maintenance and capital programmes.

Ports. Sheerness, Ramsgate, Dover, Thamesport and the wider Thames Estuary port network sit within our regular mobilisation zone. We deliver port pavement floor sawing on hard standing replacement, fuel handling area reinstatement, quayside service installation and dockside structural work.

Public sector. Kent county council, district councils across Maidstone, Ashford, Tunbridge Wells, Canterbury, Medway and Sevenoaks, plus NHS trusts, schools and government estate work. Depot floors, vehicle workshops, service yards and infrastructure buildings all appear regularly.

We’ve delivered floor sawing on more than 300 UK projects in the past six years across these four sectors, with Kent as the largest regional concentration alongside London.

Cut depth is the question most Kent specifiers ask first. The honest answer for our fleet is 420mm maximum on standard floor saws, which covers almost every Kent slab specification. The relationship between blade diameter and achievable depth is:

• 500mm blade: roughly 180mm to 200mm cut depth
• 750mm blade: roughly 300mm to 350mm cut depth
• 900mm blade: roughly 360mm to 420mm cut depth

For deeper cuts beyond 420mm, wire sawing or specialist deep-cut plant is the alternative. On typical Kent work, this is rarely the specification, because standard highway, airfield, port and industrial slab thicknesses fall inside the 420mm range.

In our experience, matching blade specification to the actual reinforcement in the slab works better than pushing a generic blade specification across every Kent job because heavily reinforced airfield concrete cuts differently to lightly reinforced industrial floor, and the blade and feed rate have to be adjusted accordingly. On an M20 concrete carriageway joint reformation programme, we adjust blade specification between the heavily doweled expansion joints and the plain contraction joints, and the productivity difference across a shift is significant.

Five points tell you most of what you need to know when shortlisting.

Accreditation. SafeContractor and CHAS are baseline. For specialist work, the Drilling & Sawing Association (DSA) is the relevant trade body. Where cutting interfaces with joint sealing, ESA membership signals genuine specialism.

Operative qualifications. NVQ Level 2 in cutting and drilling, CSCS cards, and where supervising, SSSTS. For airside airport work, additional airside familiarisation is required.

Owned plant. A contractor who owns their floor saws and services them regularly will consistently outperform one hiring plant in for each job. Ownership means operatives are practised, calibration is known, and short-notice mobilisation is possible on Kent’s overnight closure windows.

Services survey methodology. Before any cut is made, embedded services should be surveyed. Live cables, fuel mains, water mains and reinforcement layout all influence cut placement. A contractor without documented services survey methodology is taking risks they shouldn’t be.

Follow-on scope integration. Where the cut feeds into joint sealing or slab reinstatement, the cutting spec has to match what comes next. The ESA Code of Practice Section 5.1 requires joint slot faces to be within 10° of vertical for proper sealant performance, which is a cutting specification, not a sealing one. Contractors who understand this deliver better outcomes. For contractor selection at the broader Kent concrete cutting category level, concrete cutting contractors in Kent covers the wider evaluation framework.

Floor sawing in Kent is governed by:

• HSE guidance for diamond drilling and sawing operations
• The Drilling & Sawing Association (DSA) Code of Practice
• SHW Series 700 for highway pavement work
• CAA / ICAO / DIO standards for airfield applications
• CDM 2015 Regulations for construction projects
• BS EN 14188 series and the ESA Code of Practice where cutting interfaces with joint sealing
• ESA Code of Practice for silica dust control

For Kent specifiers, requesting both SafeContractor or CHAS accreditation plus the relevant trade body membership is the clearest way to verify contractor competence.

The execution matters as much as the kit and the accreditation.

Site survey and services check. Before any cut, the slab is surveyed for embedded services. We confirm drawings, scan where appropriate, and verify live fuel main locations physically before cutting on airside work.

Method statement and RAMS. Documented method statement covering blade specification, water feed, slurry management, section removal and edge protection. For live sites this includes traffic management or airside protocol around the cut zone.

Setting out. Cut lines are surveyed and marked precisely. On airfield and highway work, tolerance is measured in millimetres because the cut has to align with existing slab geometry, joint patterns or service drawings.

Water and slurry management. Continuous water feed cools the blade and suppresses dust. Slurry is collected and removed before it dries. On Kent highway and airside work, slurry containment is critical because runoff into drainage or grass margins creates environmental compliance issues.

Controlled cutting. The operator advances the saw at a rate matched to the concrete strength and reinforcement. Multi-pass cutting is used for deep cuts, with the depth increased on successive passes rather than attempted in one pass.

Section removal and clean-up. Cut sections are lifted by excavator, telehandler or vacuum lifting plant. On live airside sites, vacuum lifting is the standard to avoid drop damage to surrounding slab. Slurry is water-jetted and vacuum-extracted from the surface. Edges are cleaned ready for the next phase of work.

A meaningful Kent floor sawing specification will identify the slab thickness and reinforcement type, the cut linear metres and geometry, the required depth and width, the access constraints (internal versus external, live versus closed site), the services survey requirement, the saw type (diesel, electric, petrol), the water and slurry management approach, the section removal method, and the interface with any following work (joint sealing, concrete reinstatement, services installation).

If you’re specifying or commissioning floor sawing work in Kent, whether that’s an airfield taxiway programme, a motorway concrete joint reformation, a port hard standing replacement, or a public sector depot slab, get in touch. We’ll assess the slab, the services, the access constraints and the follow-on works, and quote the full scope properly under the relevant standards.
