The Different Types of Concrete Cutting and Breaking

Concrete cutting, can be explained in the layman's terms as the process of creating holes and openings through concrete surfaces, walls and ceilings. This process can be used for more complicated tasks along with revolutionizing tools and methods like coring concrete pile caps to removing unwanted concrete from a site. Concrete cutting, drilling and sawing are one of the greatest challenges for most of the drilling experts because the concrete is one of the toughest materials to work with due to its hardened nature. Special tools are needed to get the job done and safe without damaging the underground utilities and electrical conduits through the concrete.

The good news is that today, a wide range of concrete saws are available in the construction industry for fulfilling out different types of concrete sawing operations such as dry sawing and wet sawing. A concrete saw is nothing but a high-quality tool used by drilling experts to make cuts and openings on hard materials such as brick, masonry, and tile etc., apart from concrete. This tool can be hand-held saw or a big walk behind saw which often work with the support of either electric motors or gasoline.

Different Types of Sawing Techniques

Wire Sawing

Wire sawing's everyday need of the construction industry essential for creating highly accurate cuts or openings in steel and reinforced concrete. If you are looking forward to creating different types of shapes in a variety of different sizes, then nothing can to be more useful to you than wire saws. Wire saws, which can be diamond embedded cables used for creating holes and openings offer tremendous flexibility to contractors and helps in minimising wastage. Since wire sawing is an anti-vibration technique of creating cuts, it does not produce any types of cracks around the openings created by the contractors.

Floor Sawing

Floor sawing is the most commonly used method for cutting holes and cuts into roads, bridge decks and pavements, where awkward shapes and sizes need to be cut.

Wall Sawing

The main purpose of wall sawing is to create cuts on vertical structures inside heavily strengthened concrete such as walls. Wall saws are very close to track saws, and they are mostly used in building projects for creating openings such as doors and windows.

Concrete Cutting - Don't Let a Little Bit of Concrete Stop You

What is Concrete Cutting?

Concrete cutting is a process of controlled sawing, drilling and removal of concrete performed by skilled operators using special saws that use diamond impregnated blades. Unlike the old- fashioned dusty "jack hammer" method, modern concrete cutting leaves a smooth attractive finish and utilizes water so as not to create any dust or mess. There are many different kinds of concrete cutting but the most common are wall sawing, core drilling and slab or flat sawing.

Wall Sawing is the process of cutting openings such as doors or windows in concrete walls, usually no more than 12" thick but in some cases up to 24" thick. This is accomplished by using a saw that attaches to a track on the wall to be cut. This process utilizes an enormous 30" or even larger diameter diamond blade that can cut 12" or more of concrete all of the way through from one side. This aspect of our business requires the most skill and cannot easily be done by your average "do it yourselfer." As stated, wall sawing may entail cutting openings in concrete foundations but may also include lowering a foundation elevation, entire foundation removal and also the cutting of concrete retaining walls in part or in whole. This type of concrete cutting requires skill and experience to cut perfectly smooth plumb and level openings with virtually no dust or mess, so it is a rather expensive service. Most concrete cutting companies charge a minimum of $425 just to take their equipment to a site and cut.

Homeowners that build additions on to their home that have basements or cellars commonly find they need to cut into their existing concrete foundation to add an entry or passage between the new and existing basements. It is much easier and in most cases less expensive to have this service performed during the construction process and not after.

Core Drilling is the process of drilling perfectly round holes through concrete walls and floors. The diameters of the holes range from 1" to 12" round but average 5" for most homeowner applications. In commercial applications core holes can range anywhere up to 60" round and more. Core holes are used for "utility penetrations" such as electrical, plumbing and heating but are also commonly used for venting furnaces or clothes dryers. Although not recommended, core drilling can be performed by an advanced "do it yourselfer" and the equipment necessary to perform core drilling is readily available at your local tool rental and supply store. Most companies have a minimum charge of $250 to core a hole for you and it can take a professional as little as 10 minutes to unload his equipment, core the hole, and reload his equipment. Yet, I have seen homeowners rent the equipment and spend an entire weekend trying to core a single hole and then call a professional to complete the project. Just like with any trade a professional concrete cutter will make his job look easy.

No matter what your project is, don't let a little concrete stand in your way. Concrete can be a homeowner's worst obstacle if he or she doesn't know that there are companies out there that specialize in removing it very quickly and neatly. To find a reputable concrete cutter I recommend that you start with the yellow pages and always check them out with your local Better Business Bureau or your local Department of Consumer Protection. To get more acquainted with the industry just do a search for "concrete cutting" and check out a few websites dedicated to the subject.

It is a must for the operators to understand the user guide or operating manual and safety requirements of all drilling equipments. During the core drilling operation, the drilling operators must strictly wear protective equipments recommended by local, state or federal standards. The diamond core drilling machine operators and those involved in the drilling operation must wear proper safety equipments that include safety goggles, safety footwear, snug fitting clothes, hearing protection, head protection, and proper respiratory equipment.

Before starting the drilling operation, make sure that all the drilling equipments, especially the electrical equipments are in good operating condition. Before operating hydraulic drills, ensure that the hoses and fittings are in good condition. You must not wear loose-fitting clothes and jewelry while operating the drilling equipment. You must keep your hands and clothes away from all the moving parts of the machine.

Diamond core drilling companies ensures to provide a safe and healthy working environment for all their employees and clients. They ensure to use drilling systems and procedures accepted by commissioned Health and Safety Management Plan. They even provide extensive and continued mentoring/training for their employees in order to ensure safety use of drilling equipments. They provide training related to diamond core drilling safety methods and first aid. All drilling operators and employees are encouraged to adopt safety methods while working. All drilling operators must strictly follow safety methods recommended by the company in order to ensure efficient work with minimum risk.

You must take care before starting the drilling operation. Lock the core drill to the working surface to prevent the drill from moving so that the core bit does not bind in the drilled hole. Check for any damage in the drill bit before using it. Do not operate the drilling machine if you have not read and understood the operators manual or if you are unsure of how to run the machine. Do not operate the machine if you are you are tired or fatigued. Avoid using damaged equipments.

Avoid using drilling equipment unless you are specifically trained for using it. Never leave the power cords in or near the water. Do not drink alcohol or use any drugs before using drilling machine. Never touch the rotating parts of the machine in any circumstances. In case of any malfunctions of the machine while performing the drilling operation, switch OFF the machine and remove the plug from the power source. Do not attempt to repair the machine by yourself. Any repairs on the electric parts of the machine must be performed only by a trained professional.

Safety conscious drilling companies insist on the use of personal protective equipment. The use of personal protective equipment prevents minor and fatal injuries occurring at the drilling sites. Diamond core drilling safety manuals consists of safety program responsibilities, electrical safety measures, drilling machine safety procedures, policy statements, accident reporting, etc. The safety manual section also includes general safety rules and precautions, and safe work practices for diamond core drilling.

The drilling companies are responsible to ensure that their employees are well trained to use the drilling equipments properly. They must also ensure that their employees use personal protective equipments and adopt safety measures while performing the drilling operation.

The Different Types Of Drilling Rigs

Drilling rigs are structures that house equipment like pipes, cables, drill bits and derricks which are necessary in extracting important commodities such as petroleum from under the earth's surface. The rigs are categorized under offshore and land with the offshore handling drilling on the ocean floor and land based drills handling the drilling that is done on land.

Apart from extracting petroleum, they can be used in the construction industry in building foundation construction, roadbed, bridges and airports constructions where strong foundations are required. They can also be used in mining, drilling and water well drilling. The drilling rigs come in different types and the most suitable is selected according to the task that is at hand. The drilling rig classifications can be done using various factors, attributes or technologies.

By power

The kind of power a drilling rig uses can determine what type it is. In general, you can find mechanical drilling rigs which use clutches, transmissions and torque converters that are powered by their own diesel engines. The electric ones are those whose machinery items are driven using electric motors generating power on site through internal combustion engines. There are also hydraulic rigs which use hydraulic power, steam rigs which use engines and pumps that are steam powered and the pneumatic ones which are powered using pressurized air.

By Pipe

Rig categorization under pipe has cable drilling rigs that use cables to raise and drop drill bits, conventional drilling rigs which use plastic or metal drill pipes of different types to suit the function and col tubing rigs that use giant tube coils and down hole drilling motors.

By height

Height categorization comes in when temporarily removing drill pipes from the hole and is based on the number of connected pipes in the derrick. Single rigs pull dingle drill pipes, whereas double rigs can handle a stand of pipe that has two connected pipes in the derrick. Triple stand rigs can handle three whereas quadri stand can accommodate four connected drill pipes.

By drilling method

The drilling technology classifies the drilling rigs into non rotational rigs that include most service rigs and direct push rigs. There are also rotary table rigs that achieve rotation by turning a hexagonal or square pipe at the floor level of the drill. Top drive rigs have the circulation and rotation done around the top area of drill string on motors moving on track along the equipment derrick whereas sonic rigs use vibratory energy so that the drill string is advanced. You will also find hammer rigs that use percussive and rotation force.

By derrick position

Drilling rigs can also be categorized according to the positioning of the derrick on the equipment. There are conventional rigs that have the derrick in vertical position and slant rigs that have the derrick slanted at an angle of 25 degrees so that horizontal drilling is facilitated.

Whatever the drilling needs you have, there is always an importance of making sure you select the best for the task at hand. When you know what your options are your chances of choosing the best drilling rig are increased.

How to Choose an Air Compressor in 5 Questions

Although the number of air compressor choices can be overwhelming, selecting the right one can be made easy by asking a few important questions.
What is the application?
Air compressors are used for a wide range of jobs — from inflating tires to powering tools to operating a factory. The application will determine the type of compressor you need. For example:
Portable air compressors are well-suited for one person operating air tools
Stationary, single-stage air compressors are often used for wood shops, automotive restoration and maintenance, small businesses, or facility maintenance.
Two-stage air compressors are recommended for multi-bay automotive shops, light commercial shops and industrial applications.
Rotary screw air compressors are recommended for applications that need constant volumes of air, which would require a compressor to run 100 percent of the time to keep up with the tools necessary for the job.


What air tools will you be using?
Some air tools require more air than others. This is measured by standard cubic feet per minute (scfm). There are several steps you can take to select the appropriate air compressor based upon your tools.
First, find the tool that requires the greatest amount of scfm and multiply that number by 1.5. This will give the compressor some room for future expansion or heavier tool use. If operating more than one tool at a time, add together the scfm requirements for each tool then multiply that number by 1.5.
Next, make sure the compressor chosen offers cubic feet per minute (cfm) output equal to or greater than the requirement of the equation in step one. For example, if the tools you plan to use individually are an impact wrench with a 5 scfm rating, a ratchet with a 4 scfm rating, and a dual action sander with a 9 scfm rating, then the air compressor must have a cfm rating of 13.5 or more. This is because the dual action sander has the highest scfm requirement, and 9 scfm multiplied by 1.5 is 13.5 cfm.


If you plan to use all three of those tools at the same time, the compressor must have a cfm rating of 27 or more — a rating reached by adding together the scfm requirements of the three tools (18) and multiplying that number by 1.5.
How often will you use the air compressor?
If you plan on regular use — several times a week — then select a compressor with a 50/50 duty cycle, such as a portable cast iron or contractor compressor.
For daily commercial or industrial use, select an air compressor with a higher duty cycle, such as high performance cast iron, single stage, two stage, or rotary screw compressors.


Be aware that air tools requiring larger air consumption will require a larger air compressor to operate appropriately. This should be taken into consideration above all else.
What type of power is available?
Portable compressors typically operate on 115-volt, 15-amp circuits. Stationary, single-stage compressors and some large portable compressors operate on 230-volt, single-phase power. Two-stage air compressors that are 10 hp and larger operate on three-phase power only, while 5 hp and 7.5 hp two-stage compressors are available for single-phase and three-phase power. If no electrical power is available, a gas air compressor is required.
Do you have plans for future expansion?
If there are plans to expand the business or operation in the near future, and these plans will require more air, it’s less expensive to buy up to the next larger air compressor now than to purchase a second compressor in the future.
Use these tips to explore our wide variety of air compressor options to find one that’s right for you.
