Concrete cutting requires incredible precision, proper training, and the right equipment. Due to the complexity of the job, it should be a task reserved only for professionals.

There are many ways to cut concrete and various types of cutting machinery to get it done. In building or concrete demolition projects, the cuts can vary in depth and length. This is why a precise and well-trained hand is needed to ensure that the cuts are created in the exact size they should be.

The type of cut needed for each project should also be used as basis for the type of equipment to be used to cut the concrete. Whether you’re looking to cut curved or straight, deep or subtle lines, there is always the right equipment to get the job done.

If you’re looking for professional concrete cutters for your project then choose a local contractor who has the manpower and machinery to provide the services you need.

Regardless of whether you need to cut concrete to create windows or doors or simply would like to get concrete floor sawing services, professional contractors can get these done for you. In fact, there is a specific machine to ensure safe and precise concrete cutting for your project, and the right contractor should know which one to use.

Five methods to ensure safe and efficient concrete cutting on your construction project

Flush cutting
If you need to cut a straight line on a concrete floor then flush cutting is the best option. The flush cutting saw creates a precise straight cut at any depth, making it the perfect tool for cutting concrete or reinforced concrete.

It’s also ideal for cutting stone or bricks. With proper training, a flush cutting saw is generally easy to manoeuvre. It’s considerably smaller too, which makes it a great option for cutting in small or narrow areas that large machines can’t reach.

Hand and ring sawing
Hand saw and ring saw are great cutting machines to use for concrete cutting. They can work wonders especially when manoeuvred by skilled hands. These types of machines are perfect when you need to create precise cuts without much regard to the depth.

These cutting saws are best used for wall sawing, cutting expansion joints and doorways, and removing footpath and concrete slab. They are highly efficient and use a dust and water system to avoid dispersion of debris which could cause disruption of work in your site.

Hydraulic and High-Frequency Sawing
Concrete cutting can be noisy and disruptive. This is why it’s not always the easiest task to manage if you’re working on an indoor project. It can quickly become messy and time-consuming with the preparation, actual cutting, and post-cutting cleanup.

Hydraulic and high-frequency sawing by professional concrete cutters is a quick fix to the problem. These types of cutting saws generate low noise and are fume-free, which make them the perfect option for indoor projects. They’re also easy to manoeuvre, making concrete cutting a lot easier.

Road sawing
Large scale indoor and outdoor projects such as floor or road sawing often require special types of machinery that will ensure that the cuts are precise with the right depth. For these projects, special concrete cutting saws must be used to ensure perfect cuts.

Professional concrete cutting service contractors often use equipment that can create cuts with a depth of 375 mm to 500 mm. These cutting saws can cut through floors, asphalt, and pavements.

Diamond saw cutting
There are two types of diamond concrete cutting saw: the dry cutting saw, and wet cutting saw. The dry cutting saw generate the best result when successional cuts are made on the same spot to increase depth.

Meanwhile, the wet cutting saw can be used continuously as it uses water to prevent dispersion of dust and prevents the saw from overheating. Both cutting saws are often used in large scale projects as they can create precise and smooth cuts on concrete.

Concrete removal and demolition

It’s common in renovation projects to alter the size or totally remove concrete, whether it’s concrete floors, slabs, pillars or walls, among many others. Usually, concrete removal is regarded as a messy task that needs a lot of precaution and planning.

While it is true that concrete removal can be stressful, it doesn’t always have to be as costly and complicated of a task as most people regard it to be. With the right professionals, it can be done in the fastest and easiest way possible.

As established earlier, one of the perks of working with concrete cutting and removal contractors is their plethora of high-quality machinery. But more than that, they are the best option for the job because of their training and safety gear. They know how to cut and remove concrete in the safest and non-disruptive manner possible.

Core drilling

Apart from concrete cutting and concrete removal, core drilling is also another highly sought after service from professional contractors. Drilling on concrete is often sought before electrical or plumbing installations in buildings.

A modern core drilling machinery can drill up to 1000 mm in-depth, with a diameter of up to 1200 mm. Professional contractors can do regular drilling, inverted drilling or stitch drilling — all depending on the type of holes needed for your home’s engineering and architectural plan.

When working on a renovation or a new building, knowing what types of concrete services you’ll need from professionals can make the entire process a lot easier for you. You can effectively relay to professional contractors what you need and they can guide you through the processes needed to get it done.

And since a good contractor essentially means easier building and renovation, you must do your due diligence before committing to one. Choose contractors who have the experience and skills needed for the job and are situated locally.


Tefcold owner becomes Interlevin MD

UK: Torben L Christensen, the owner of Tefcold, has taken over as MD of Interlevin Refrigeration.

He replaces Jonathan Corns who was appointed MD last year following the company’s acquisition by Tefcold, the Danish family owned commercial refrigeration company.

“We see Interlevin as a very important part of the Tefcold Group and for Interlevin to reach its full potential we believe we have an obligation to get the best possible integration into the group,” said Christensen.

“The group management have decided that I take over as MD in order to make sure we share best practices around processes through the group and grow Interlevin within the marketplace. While we have seen many operational improvements during the last financial year, we know that there is still room to grow and maximise our offering within the commercial refrigeration sector.”

Survey seeks to boost womens’ careers in RACHP

UK: The IoR’s Women in RACHP Network is inviting the refrigeration, air conditioning and heat pump sector to complete a survey to gauge attitudes towards women in the industry.

As the RACHP sector continues to struggle to bring more women into the industry and utilise female talent to its full potential, the Women in RACHP Network is undertaking research in this area in an aim to drive change. The network is encouraging everyone in the sector to take part in the online survey which is intended to benchmark the industry’s benefits and attitudes towards women and explore what should be done to close the gender gap.

It is clear that women are under-represented in engineering and the RACHP sector is no exception.

“Although there are no official figures in the UK the reality of the RACHP sector is comparable to that of the US where women represent only 1.2% of the HVACR workforce,” said committee member Astrid Prado, marketing manager at Star Refrigeration.

Maintaining that a reputation for the refrigeration and air conditioning being “man’s work” is failing to attract talented women at all levels, Prado said it continued to operate with work packages “developed decades ago for a largely male, full-time workforce” and was “failing to keep pace” with the expectations of the modern workforce.

“In order to drive change, we must redesign current workplace practices to accommodate the diversity of today’s workforce who want flexibility, equal opportunities, and better access to training and development.”

Prado added, “Although this is only a starting point, the outcome of the research will serve not only as a point of reference but as industry guidance for the future, to help us improve and ensure we offer an attractive package to women so that they are inspired to join and stay in the industry.”

The survey is open to both men and women working in all roles and from all pay grades and structures. All entrants completing the questions before December 1 will be added to a prize draw to win a Latitude travel charger set.

The Women in RACHP Network was set up by the Institute of Refrigeration as an educational and networking group to encourage diversity in the workforce and promote the role of women in refrigeration.

Contractor group moves to allay fears on R22

USA: The USA’s largest air conditioning contractors’ association has moved to allay US fears regarding the future availability of R22 refrigerant.

The production and importation of the main air conditioning refrigerant R22 will be banned in the US from January 1 under Montreal Protocol phase-out agreements. While existing stock and reclaimed/recycled material will still be able to be used, there is concern in the market regarding future prices and availability.

The Air Conditioning Contractors of America (ACCA), which represents over 60,000 members and 4,000 businesses, says it believes there will be enough stockpiled and reclaimed R22 to allow for a smooth R22 transition.

“Do we know how much R22 is and will be available? No, but there are some indicators that show that R22 should be available for several years,” says ACCA vice president, public policy & industry relations on the association’s website.

This he bases on ACCA’s research and in working with refrigerant manufacturers and reclaimers.

He quotes Arkema’s director of sales saying: “Arkema has done significant market research and we estimate that there is sufficient R22 to serve the market needs for at least five years.”

Haun also stated: “Take R12, for instance, which was phased out on January 1, 1996. There are still R12 systems operating in the US and contractors are still able to purchase R12 to service those systems.”

However, according to a large reclaimer, one of the challenges that could decrease R22 availability is the mixing rate of reclaimed product. Some reclaimers lack the ability to separate refrigerants when they received recovery cylinders that are made up of a cocktail of refrigerants. ACCA fears that the increased mixing rate and inability to separate those products could have an impact on the supply but is not certain that that alone would reduce the years of projected availability.
