John F Hunt Concrete Cutting
John F Hunt Concrete Cutting (South) is a Division of John F Hunt Limited who undertake technical demolition and structural alteration projects, by combining traditional demolition skills with the professional services provided by the Concrete Cutting and Diamond Drilling teams. They deliver complex projects, both in challenging central London locations and across the South of the country. John F Hunt Concrete Cutting (North) is a Division of John F Hunt Regeneration, who carry out the decommissioning and industrial dismantling of brownfield structures nationwide. The Concrete Cutting and Diamond Drilling teams support the Regeneration activities throughout the Midlands, North and Scotland.
With our extensive proficiency gained through a history of working on logistically challenging sites and sensitive environments, we can provide valuable advice and technical support on all forms of concrete cutting and controlled demolition.
Our ability to respond to our clients’ needs quickly and efficiently, is a key factor in the continuing growth and success of the company.
Providing innovative and creative bespoke solutions, makes us the go to company for our client’s requirements.
Diamond Drilling
Fast and virtually silent, Diamond Drilling is the most environmentally sensitive way of creating a precision opening in any structure. Rigs have a single hole drill capacity from 8mm for smaller anchor bolts and dowel bars, up to 1000mm in diameter for installing large pipes, and can be operated manually or automatically from virtually any angle.
Our self contained, hydraulically driven trailer rigs, drill cores of up to 750mm in diameter. Requiring no fixing, they enable work on external jobs where securing to a surface is not an option.
The ‘Stitch Drilling’ technique, where holes are drilled next to each other, provides countless options, with opening sizes becoming unlimited.
When noise pollution is a major consideration, concrete cutting and diamond drilling are fast and virtually silent, enabling work to continue and deadlines to be met.
Wall and Track Sawing
A fast and precise straight line method to create openings in concrete and masonry. It is typically used to cut appetures for doorways and windows, as well as reducing wall heights, and forming lift-shaft openings. With up to 1000mm depth of cut, track sawing is also ideal for making separation cuts between walls and floors prior to demolition operations.
Track saws have a digital cutting head, blade guards, power pack and track system, all anchored to the surface being cut. The cutting head moves along the track powered by 3 phase electricity.
Our blades range from 450mm to 2.2m in diameter, giving us the ability to cut to depths in excess of 1 metre. Machines can also be fitted with flush cutting flanges enabling tight cuts to any structures.
Our fleet of over 20 track saws are remotely controlled making them safe as well as precise and efficient pieces of equipment.
Wire Sawing
Wire sawing is a very versatile and efficient method of cutting, with the operation being dust and vibration free. It is typically used for cutting large sections of heavily reinforced concrete. The procedure can be used successfully under water, which is ideal and cost effective when working in tidal situations or water filled tunnels.
Wire saws are perfect in complex, awkward or confined spaces. A diamond beaded wire is fed around the structure and through a pulley system whilst applying a constant pulling force making the wire carve through the material.
Where wire sawing is the only solution, i.e. on ground bearing slabs over 1m deep, the plunge wire sawing method is used.
Through continual investment, we use the most advanced, high frequency wire sawing technology and equipment in the industry today.
Floor Sawing
We have an extensive range of diesel and 3 phase electric floor saws, capable of taking blades from 450mm to 1500mm which gives us cutting depths of up 630mm. Our Floor Sawing services are perfect for cutting external horizontal surfaces such as roads, pavements and airport runways, as this method produces clean edges in a very short space of time.
We also specialise in sawing internal floor slabs such as in shopping malls, factories, supermarkets and hospitals, where a depth of 480mm can be achieved.
In these locations, the speed of operation, consideration of surroundings as well as the safety of the general public are of the utmost importance.
Utilising our self-propelled cutting saws, we also offer an expansion joint cutting service, creating joints up to 20mm wide, quickly and accurately.
Drilling, Bursting and Crunching
Concrete Bursting or Hydraulic Bursting is a safe and environmentally friendly method of weakening and demolishing large concrete structures, through a silent and vibration free demolition technique. It enables the removal of smaller more managable pieces of concrete without the use of large machinery.
This system is ideal when the required concrete removal is very close to another structure, raising concerns regarding the effect of vibration on the building’s foundations.
The technique of ‘Crushing’ is used for removing concrete with hydraulic concrete crackers, allowing easy reduction of reinforced concrete into rubble.
Due to this method being almost noise and vibration free, its use is preferred over conventional demolition processes.
Remote Controlled Demolition
Our cost-effective fleet of electro-hydraulically powered, remote controlled robotic excavators, allow work to proceed in the smallest of areas with no harmful fumes and by design, the removal of the operator from any hazardous situations. With an array of attachments and minimal noise emissions, robotic BROKK demolition also alleviates hand-arm vibration problems.
With our extensive fleet of modern BROKK’s ranging from 60 up to the 400, we are able to operate in many confined, difficult and challenging locations such as basements and stairwells.
Small machines weighing only 380kg are ideal for scaffold access whilst the Brokk 400 is as powerful as a conventional excavator. ‘Cracking’ concrete generates little noise or vibration and less structural damage risk.
Saving time and money, BROKK’s productivity is outstanding, enabling safe, environmental demolition in the most testing sites.
Floor Planing
We offer a concrete Floor Planing service for the removal of surplus or unwanted material. This is often utilised for the levelling of screeds from floors and slabs after poor construction. Suppression systems are fitted to reduce the amount of dust created within the working environment.
We provide concrete scabblers, floor scabblers and concrete planer equipment operated by our competent and experienced staff.
We supply handheld diamond drilling equipment for the cutting of openings and the removal of small obstructions.
Our range of equipment includes:
- Ring saw
- Solid saw
- Chain Saw
- Hand-held diamond drills
- Hand-held chasing units
Ferrous Scanning
To identify the position of hidden metal objects and rebar within a concrete structure without any intrusive or damaging investigation, can be very difficult. Our Ferrous Scanning service enables the non-destructive inspection and identification of metals, whilst providing measurements and pin-point positioning for drilling and cutting.
We give you visible results as to rebar content on a hand-held screen. Our technical operatives use the portable unit for structural analysis in a non-destructive manner.
Data is automatically recorded over lengths of up to 30 metres, providing 9 clear images and accurate measurements for reinforcement or rebar at depths of up to 100mm.
With clear 2D images of the metal, this allows us to provide on-the-spot structural analysis, to enable precision drilling without fear of hitting metal.
Training and Accreditations
Training is key to maintaining our exemplary health and safety record, with our operatives receiving regular task specific training to industry standards. We provide ongoing training for all teams including PASMA, IPAF, BROKK operator and confined space training.
100% of our workforce is CSCS, Face Fit and Asbestos Awareness trained, with our senior supervisors being SMSTS or SSSTS trained.
We are members of a number of industry associations including the Drilling and Sawing Association.
We operate in accordance with our Integrated Management Systems which are accredited by UKAS and compliant with ISO 9001, ISO 45001 and ISO 14001.
