The concrete cutting experts or contractors are essential to handle a variety of constructing and renovating house projects efficiently. Most of the concrete cutting Sydney professionals are well experienced and skilled, they know what materials are inside the concrete like rebar or any other materials that are embedded may cause damages.

Reasons for concrete cutting:

Most of the people, industries, and projects are making use of professional concrete cutting services. Here are some of the essential reasons for concrete cutting.

Renovation or reconstruction of a building:

Most of the old buildings and even new buildings will need to have some changes to the exclusive design. The buildings which are falling out of date, and remodels and renovations might require cutting down a few concrete walls. This is one of the main reasons why concrete cutting is necessary. Apart from just renovations, many people often want to install more doors, new window openings, and install a mini pool in their backyard would require cutting of concrete walls, concrete slab, or concrete floor. 

For safety regulations:

Another use of concrete cutting or drilling is when it is necessary for safety purposes. The buildings must have to follow the safety regulations. Both the regular exits and emergency exits are needed to be maintained properly and the dimensions should meet the capacity requirements. Concrete cutting is needed to make new holes for the need of more doors as emergency purposes or to widen existing door frames if the doors are too small.

For better productivity:

The main reason to consider concrete cutting is when the construction needs to increase productivity. There are many different types of buildings such as schools, offices, restaurants, colleges, or theatres, which need more doors and windows. More exits and entrances allow more employees and visitors to get in and out safely as an emergency. Keeping the building cool during summer and spring and warm in the winter and fall is another consideration. More buildings used this technology in Sydney. To know more about it you can search for concrete cutting Sydney buildings.

What is concrete? 

Concrete is a composite construction material that is made of cement, water, fine aggregates (sand or crushed stones), and coarse aggregates (gravels). Through the chemical process called cement hydration, the paste hardens and produces crystals that interlock and gains strength by binding together to form the rock-like mass known as concrete. Concrete is an artificial rock-like material used for various structural and constructional purposes.

Methods in concrete cutting:

All You Need To Know About Core Drilling

about core drilling

In the world of construction, there are many instruments being used for various functions nowadays. Think about the different tools used for cutting, drilling, boring, plastering, holding-in-place and likes. Amongst these equipment mentioned above is the core driller.

A core driller is a machine or equipment which is equipped with special types and grades of drill bits essential for drilling holes of large or small diameters in already constructed structures. A major use of the core drilling is in the construction of manholes for sewer outlets and fitting pipes in buildings.

It is reasonable to have questions about what core drilling really is to get more familiar with the concept. If you need answers to these questions, ensure you reach the end of this post as it provides answers to every question you have in mind about core drilling.

Question number one: What is core drilling really all about?

Core drilling, in general, is the process of creating a hole or penetrating through concrete, CMU (concrete masonry unit), brick or stone using a diamond or carbide-tipped drill bit. This is usually used in the construction industry so things can be fitted inside the holes drilled. Core drilling also is used for exploration in mining and all related engineering fields.

You should also know that the drill samples (a piece of concrete inside the drill) is first sent to geological experts for their analysis of the samples. They make the decision whether or not the area should be used for further construction work or should be abandoned.

Question number two: Are there any types of core drilling?

Of course, there are. Below are the principal types of core drilling:

Diamond core drilling: Diamond core drilling comes from the diamonds used to make the drill bits. The drill bit is made of small industrial-grade diamonds arranged into a soft matrix. You should take note that the more you use your drill, the more the diamonds on the tip get exposed to contact.

Reverse circulation drilling: Reverse circulation drilling has a lot of advantages over the other types of drilling methods. It uses dual wall drill rods that consist of an outer rod with an inner tube. The inner tubes allow the drill cuttings to be transported back to the surface steadily.

Question number three: What are the precautions to take when core drilling?

During core drilling, there are some safety procedures you should get accustomed to as operating a core driller is a dangerous job to do. Here are some precautions you should take when core drilling.

  • Never take alcohol or enhancement drugs before using the core driller.
  • Ensure you have your PPE (Personal Protective Equipment) when using the core driller.
  • DO NOT make any adjustments while the machine is operating.
  • Avoid cleaning chips with your hands. It is advisable to use a brush.
  • Remove all chuck keys and wrenches before operating the drills.
  • Ensure the cutting tools are running straight before starting the operation.
  • DO NOT place tools or equipment on the drilling table.

Following all these procedures while operating them should keep accidents and injury at bay.

Question number four: What are the Advantages and disadvantages of core drilling?

Advantages:

  • Core drilling is way faster and efficient.
  • It requires fewer labour hours to get the job done.
  • You spend less while operating core drills.
  • Core drilling cuts more precise holes when compared to other drilling methods.
  • You get to make holes once thought impossible.
  • You don’t have to worry too much about the cooling system as the machine design has got this covered for you.
  • They save a lot of energy during cutting. This can be traced to the fact that they require less thrust to drill when compared to the other drilling categories.
  • They are also easy to sharpen.
  • Core drill bits have a range of diameter sizes.

Disadvantages:

  • Taking cores always leave weak points within the element. This can affect the integrity of structure and durability performance.
  • Coring can damage the structural performance of the element, especially if the coring damages the rebar. This is the last you want during coring.
  • Getting core locations can be very subjective. There are just too many things to put into consideration.

Question number five: Who is certified to use a core drill?

An engineer with the appropriate licenses.

Question number six: What is the importance of core drilling?

  • One of the most important aims of core drilling is for the collection of samples of what was removed from the site. Other importances are:
  • It helps geologists evaluate properties of the land they are to build on. This is important for evaluating the best design for a particular place.
  • It helps engineers and construction workers make accurate holes for proper installation of building components.
  • It is used in the preliminary construction of manholes, ducts, anchor installations and so on and so forth.
  • Owing to the fact that they don’t do too much damage to the overall structure, they are used well in renovation projects.

You as a core driller should get used to the props of the core driller. Do not forget to practice proper maintenance of your core drills. Here are some maintenance tips for keeping your core drills.

  • Make sure your bit is well sharpened.
  • Do not realign the drill once the hole has been started.

Know your equipment.

Apart from these, if required, you should take help of a professional company of core drilling services to avoid the injuries, mistakes, and other factors.

The Roles of Geologists in Mineral Exploration: Australia

You could take a look at the aspects of Australia’s mining and discover quite interestingly that the country is home to some of the world’s top-quality of mineral resource. In fact, it would be most interesting to know that the Argyle mine in Western Australia stands as the world’s leading producers of diamonds by volume.

But how exactly does the country discover the resources it explores?

Two words: Infield Geologists.

What Geologists Do?

Geologists go into the field to explore most of the country’s rocks and its constituent. These highly trained professionals and experts in the field approach the earth with understanding and get samples for the lab through core drilling. They then identify and test for the presence of minerals in these constituents of the earth.

How do these Geologists discover more minerals?
Geologists by core drilling drill rocks in prospective areas of mineral exploration and determine the constituents of the rocks in those areas.

Core Drilling: A Path to Exploration

Core Drilling is a very old drilling method much different from conventional drilling. It makes use of coring drill bits coated with diamond. These drill bits in core drills are the cutting tools and they spin fast and go at high revolutions per minute, typically between 300 to 1200 rpm.

Laboratory Techniques

After the core drilling process, the geologists get back into the lab and test the core samples they have obtained. The core samples which they get in the core drilling process is analyzed to determine its constituents. For suspected areas of exploration, the geologists, in their duties, might need to obtain further samples at the regions to ascertain the likelihood of getting more minerals from the grounds.

Back to the Drilling Grounds

When more core samples are needed, the geologists go back to the core drilling grounds and get more sample from the earth. These high-quality samples are then once again taken to the lab, and there testing continues.

In the world of mining and mineral exploration, geologists continue to play a very vital role in helping the country advance by finding more minerals and digging for more of the country’s resources that lie within its crust.

Earth Exploration: Analyzing Rocks and Soil Properties through Core Drilling

You might have learnt from Middle School Geography that rocks and soils consist of many minerals. But just how much minerals do these landforms contain? Core drilling provides the most accurate path to answering that question. In this blog, we bring you everything you need to know about core drilling and its applications in the world of the construction and mineral explorations.

What Is Core Drilling?

Perhaps once or twice you have used a drill on a personal project and managed not to screw a hole in your hand. Either way, you should be a bit familiar with how drills work. Core drilling works on similar principles.

Core drilling is a rotary drilling method that makes use of ring-shaped drill bits which sometimes have diamonds or carbides of tungsten around them. These diamonds and carbides used in core drilling are the drill’s cutting tools.

In core drilling, the core drill is placed against the surface of the material to be drilled─in this case rocks. Once turned on, the drill begins rotating, usually in the clockwise direction, at a high speed until a core sample is obtained.

And what exactly is this core sample?

Simply put, the core sample is the round bar of material ─ in this case rock ─ you get after a certain portion of the material has been drilled.

How does Core Drilling Assist in Determining Rock Properties?

Core drilling is a process that can be used to produce high-quality core samples. It is this core samples that will be used to check for the mineral content in the rock.

These core samples can be taken to the lab and analyzed, subjecting them to both qualitative and quantitative analysis to ascertain their physical properties. The properties of these samples discovered after the analysis usually provide an accurate idea of the property of the rock it was drilled from.

Other Applications of Core Drilling.

Here are some other applications of core drilling in the geological field:

●     Infill Drilling in underground mines.

●     Determining the suitability of grounds for construction

A rock mechanics engineer after core drilling can analyze the rock mass to determine its mechanical and hydrological properties. By doing this, the engineer is able to decide whether construction can be done in the area from which the rock mass was obtained.

In soil mechanics, the geotechnical engineer uses the soil sample gotten from the core drilling site to obtain information on whether the soil layers must be reinforced or sealed to withstand the stresses of the proposed construction.

Concrete Cutting: Beyond Just Having The Right Tools

Concretes can be tough, resilient materials and very difficult to cut through. But in most cases, this only occurs when you don’t have the right set of equipment. With the right blades and tools, you can cut through just about any concrete. Having the right tools is not enough, though. There are also other technical processes that must be mastered if concrete cutting is to be done correctly.

So to put it simply, it’s not just about having the right tools; it’s also in knowing when, and how, to use them.

In this blog, we bring you some very important tips that are sure to make concrete cutting even easier for you.

Concrete Cutting Processes: The Right Tools Used The Right Way

1.    Making small cuts

Small rough cuts can be made using a sledgehammer and cold chisel. However, a circular saw that has a special blade is the best choice. There are three basic choices that are available.

2.    Economics

If you’re looking to do just one minor concrete cutting job, then you might want to use a blade that’s not so expensive. For example, you could use an abrasive corundum blade. It can cut through concrete and asphalt but it is not as fast as the rest of the available blades. So if you need to make only some few shallow cuts, and you’re looking for cost-effective ways to make it work, these types of blades might be the economical choice for you.

3.    Job Quality Control: Wet or Dry-cutting

In concrete cutting, as a professional, the quality of the job you attend to is very important. It should be easy for you to decide whether to use a dry or a wet-cutting diamond blade on the job.

Diamond blades are metal blades with diamond composites bonded to the edges and the perimeter of the blade.

  • In using a dry-cutting diamond blade, you must work at making gradual cuts into the concrete so that the blades you use do not overheat.
  • A wet-cutting diamond blade, however, serves the advantage of keeping particles of dust flying in the air minimal. It requires a constant supply of water though for the blades to remain lubricated and cool for the rest of the time.

Using this blade in concrete cutting ensures that your work is done in the shortest possible time.

4.    Power Source

Concrete cutting equipment are sometimes hydraulic or electric powered, or in some cases, they make use of diesel oil. Knowing which one works you’re most comfortable with, even though that knowledge appears partly insignificant, is one of the crucial ways to improve the quality of delivery on your jobs.

Seven Advantages of Employing Concrete Cutting Processes

There are more conventional ways of removing concrete. However, none of these techniques compares with concrete cutting. Concrete cutting remains by far the best and most trusted technique in dealing with the most fatal of concrete flaws.

Advantages of Concrete cutting over conventional cutting procedures

  • No patchworks required: Concrete cutting is the cleanest way to make cuts on curbs and damaged roads. Unlike other conventional techniques that will require site cleanups after the procedure, concrete cutting makes neat and precise cuts into exactly where you need them.It remains solidly rooted as the most accurate technique in making cuts into damaged concrete.
  • Dust free process: You can go for wet or dry cutting. Either way, you can be sure that minimal dust is going to be raised. There is no friendlier way to carry out cutting processes than to employ core cutting processes.
  • Small work zone: When it comes to concrete drilling, you don‘t need to block out too large an area or completely close down roads. All that won’t be necessary. Why? Because the high level precision of concrete cutting allows it to demand only a small work zone for the procedure.
  • Fast: No other conventional cutting technique is as fast as concrete cutting. When it comes to making top-notch repairs in real time, there is no better option than to go for concrete cutting.
  • Disruption free:Concrete cutting techniques produce the least amount of noise. Other convention cutting methods are quite lousy and have a trademark for disturbing the surrounding. However, with concrete cutting, you can guarantee that your work zone and the areas around it are completely free from noise and appliance disturbance.
  • Operation in enclosed spaces: It can be a little bit difficult to get other conventional cutting techniques to perform efficiently in enclosed regions. Concrete cutting on the other hand thrives in these spaces.
  • Safety:Accidents happen at sites, but truth is, they don’t have to. In fact, they can be prevented. Employing concrete cutting processes rather than other conventional cutting methods is one sure way to reduce the risks of hazards at the construction site and ensure that your work is done better, easier, and much faster without you putting yourself or any of your coworkers in harm’s way. So, why not go for concrete cutting methods the next time your concretes need to be tidied.

How to Know When You Need Concrete Cutting Services

You may need concrete cutting services to avoid a future disaster or when you’re looking to build, but it won’t do you much good if you can’t tell when you need you need professional concrete cutting services. Below are a couple of common reasons that come up in a lot of home or business establishment, which can as well be yours.

Concrete Cutting Services

MAINTAINENCE

Disproportionate alignment: The concrete surface should typically be straight and aligned with each other, so when you an unequal alignment(one part going upwards and the other lower) it’s a sign that you’ll need concrete cutting services. Though it may not seem like much of a problem, but it’ll eventually start falling apart and leave a part of it exposed; causing pot holes on the long run.

Discolouration: Discolouration occurs due to changes in cement or when there’s a leakage underneath that you can’t see from the top. You’ll need it cut, dug out and refilled by a company that does concrete cutting.

Stagnant water: Whether it’s a concrete sink or concrete bathroom flooring, it really is annoying when water collects in little spots when it supposed to flow off in a particular direction. You’ll need concrete cutting services to drill in and ensure the drainage is moving to one direction as is required.

Sewer lines and broken water pipes: Concrete cutting services are effective because of their ability to cut through walls within very small space to access sewer lines and water pipes.  It’s quite a pickle when your water pipes get clogged or damaged, since that will hamper your entire sewage system. You’ll need to get your plumber to determine which area the problem is coming from, then hire a concrete cutter to cut out that portion carefully so as not to affect your pipes.

Removing concrete: It’s never a good idea to remove or move large concrete blocks with your bare hands and on your own if there is a need is a need to that. You can cause yourself harm. It’s a better idea to let the professionals handle it, as they would cut the concrete into appropriate bits before moving it which is much safer.

REMODELING

Remodeling: If you’re just looking to remodel your house, you’re going to need to make cuts in walls for new structures such as windows, doors or even cut down the whole wall if necessary.

  You may want to install a new pool in the backyard, add a small kitchen, bathroom or pave a path to the house through the garden, this would require cutting concrete.

It could also be in a work setting and you need to make a couple of changes to your office for efficiency or to appeal to aesthetics. It’s usually a great idea to let the professional do it so you don’t mess it up and leave your office inhabitable for a while.

All You Need To Know About Applying Road Saws

Having received so many questions about the subjects from clients and the general public, we have decided to create a blog to help answer these questions. Having said that, here’s everything you need to know about what a road saw is and it’s applications.

Image result for https://www.hardcutconcretesawing.com.au/road-sawing/

What is Road Sawing?

Road sawing is the process of utilizing heavy machinery, referred to as road saws, to make cuts into the surface of solid materials like roads (hence the name).

What are Road Saws?

A road saw is a heavy machine used to cut solid surfaces e.g. bricks, concrete, asphalt, masonry. It is either powered by fuel, electricity, or hydraulic or pneumatic pressure depending on its model. Some road saws can be handheld while others are operated as a big walk-behind saw. They are also called concrete saws.

The road saw is used for cutting holes in roads or material similar in thickness. The basic mechanism includes cross braces mounted on a truck body, with multiple cutters that can slide in and out on either side of the truck body, to position the cutters along pre-marked lanes lines on the road.

The cutters are dropped and energized so it can cut through the road with the required hole depth. There is also a water supply through nozzles directed towards the nozzles to cool and lubricate the blades. When the cut is finished, the cutters are withdrawn and the water is turned off. A different nozzle directs air to the cut to blow off with a blast dirt, water and dust from the cut hole.

Using Road Saws

Here are a few things to consider when using a road saw are:

  • Be sure not to force the blade of the road saw into a cut. The most effective way to cut through fast and efficiently is by letting the weight of the saw and blade handle the cutting.
  • Don’t use your hand saw for an extended period of time at a time. This measure is carried out to prevent it from overheating and also to prolong the shelf life of your road saw.
  • Protect your body parts (with safety helmets, half-face masks and protective goggles) that could sustain permanent damage from this work like your ears, eyes and lung. Road saw usage is a very loud and messy activity and road saw accidents are very common.
  • If you’ll be using your road saw for many DIY project, a diamond blade is your best option.
  • Never forget to examine the road saw’s blade to confirm if it is in good condition for use and to know if cleaning or servicing is required.
  • Buy suitable diamond blades for your road saw according to the task requirements.

It is also advisable to do extensive research on road saws before handling one. All newly purchased road saws come with instruction or operation manuals, these have basic road saw operation how-to.
