Concrete cutting and their benefits

Cutting concrete is difficult

Concrete is strong and very heavy. It is physically demanding to cut

It is cut gradually, in sections

You have to allow for at least 3 times the size of the hole

Don't forget the tons of dirt

One wall in a flat can weigh up to 2 tonnes, so take waste disposal into account

If concrete cutting is most often associated with renovation and demolition, it is also used in new construction. All electrical wiring and data installations need grooves that are cut into newly constructed walls and then overlapped and smoothed.

Concrete cutting is done using a variety of tools and techniques, including diamond blades, core drills and high pressure water jets. The selection of the correct technique depends on the specific project, the thickness of the concrete, the presence of reinforcement, and the desired accuracy of the cut. Diamond wheels are most commonly used because of their ability to cut even the hardest materials with minimal wear.

The cost of cutting concrete is influenced by several factors. One of the main factors is the thickness and type of concrete. Thicker and harder concrete requires special tools and more time to cut, which increases the cost. According to statistics, the average price for cutting concrete up to 10 cm thick is around €20-30 per metre running, while cutting concrete over 20 cm thick can cost up to €50-70 per metre running.

The complexity of the project is another important factor. Complicated cuts that require high precision or work in confined spaces are more costly. For example, cutting holes to install new windows or doors in existing concrete walls is more difficult and expensive than simple cuts in an open space. The cost of such specific cuts can be 20-40% higher than conventional cuts.

The construction and accessibility of the cutting location also affect the price. Working at heights, in confined spaces or in areas with limited access requires special equipment and additional safety precautions, which adds to the cost. Working in difficult conditions can increase the cost of cutting concrete by 15-25%.

Another factor is the cost of labour and equipment. In areas with high labor costs, concrete cutting prices are higher. In addition, modern equipment and tools that improve accuracy and efficiency can be expensive, which is reflected in the overall cost. The use of advanced technologies can increase the cost of concrete cutting by 10-20%.

The use and maintenance of special tools such as diamond wheels and core drills also contribute to costs. These tools have a limited service life and their wear depends on the hardness and type of concrete. Regular maintenance and replacement of worn parts are essential to ensure quality and safe cutting, which increases operating costs.

Project location is an important factor affecting the cost of concrete cutting. Service prices can vary by region, with urban areas typically having higher costs due to higher rents and wages. According to surveys, concrete cutting prices in urban areas can be up to 30% higher compared to rural areas.

Statistics show that the demand for concrete cutting is increasing, especially in the context of construction and renovation work. According to estimates, the concrete cutting market is expected to grow at around 5-7% per annum over the next five years, owing to increased construction activity and infrastructure upgradation.

Concrete cutting is a challenging and technically complex process that requires special equipment and skilled manpower. The cost of concrete cutting is influenced by several factors including the thickness and type of concrete, complexity of the project, condition and accessibility of the site, cost of labor and equipment, use and maintenance of tools, and the location of the project. With the increasing demand for construction and renovation work, it is important to understand these factors and plan concrete cutting costs effectively.

Concrete cutting is a common construction activity that involves cutting concrete structures into smaller sections or creating holes in them - penetrations. It is used in a variety of construction work such as renovation, demolition, creating openings for windows, doors or plumbing.

Concrete cutting is specific in that concrete is hard and very heavy, so working with concrete walls is physically demanding and the concrete has to be cut gradually in small sections.

Cutting concrete panels

In prefabricated houses we often encounter the need to cut concrete panels, for example when creating new openings for doors or windows or enlarging existing openings. This is practically the only way to change the layout of prefabricated flats.

Diamond cutting of concrete

The most commonly used method is diamond cutting. It is a precise and efficient technique that minimises vibration and noise. Diamond wheels can cut concrete, reinforced concrete and masonry. The cutting is done using special machines that ensure accuracy and speed of work.

This method is suitable for reinforced concrete walls. It is accurate, fast and minimizes vibrations that could damage surrounding structures.

When cutting concrete walls, it is important to note that multiple cuts need to be made, not just around the perimeter of the desired opening. Because of the fact that cutting concrete parts produces very heavy pieces of concrete blocks weighing from 50 - 100 kg/piece. Holes and walls are cut gradually, in parts.

What is a diamond cutting wheel?

Diamond cutting does not use real natural diamonds, but synthetically produced diamond grains that are produced using extremely high pressure and temperature. They are therefore not diamonds, but they are similar in strength. These are then mixed into the cobalt mixture from which the cutting wheel is made.

Core hole drilling

Core drilling is used to create holes for various installations such as electrical wiring, water pipes, fume hoods or drains - that is, drilling large diameters that cannot be done with a commonly available drill. This is a precise method that minimises damage to the surrounding structure. Also, care must be taken when doing this to break the iron reinforcement in the concrete.

Ensuring static stability when cutting concrete

In the case of large openings in partitions or when demolishing load-bearing walls, it is necessary to ensure the statics of the building. This means that a temporary or permanent replacement for the load-bearing function of the wall is built. Welded steel "U", "I", "L" profiles or load-bearing ceramic-concrete beams with steel reinforcement type KP7 are most often used, which take the load of the removed wall or also serve as lintels for the openings. The demolition of load-bearing walls must be approved by a structural engineer, who also takes into account any previous construction work by your neighbours above and below you. And, of course, a majority of the neighbours also have an opinion on the cutting of load-bearing walls.

Iron support when cutting out a piece of wall in a concrete wall

When renovating a house or apartment, you may need to cut a hole in a concrete wall. Whether it's to create a doorway, window or other passageway, it's important to ensure the stability of the wall during the cutting process and even after it's finished. Iron support is used for this purpose.

Types of iron support:

  • Support posts: these are vertical support elements that are placed underneath the opening in the wall. The posts should be strong enough and must be anchored into the floor and ceiling.
  • Support beams: Beams are used to carry the weight of the wall above the opening. They are placed horizontally above the opening and supported by the posts or walls at the sides.
  • Angles: Angles are used to reinforce the corners of the opening and to connect the posts to the supporting beams.
  • Temporary supports: These supports are used during the cutting process to support the wall and prevent it from collapsing. Once the cut is complete, the temporary supports are removed and replaced with permanent iron supports.

Material Selection: Steel is commonly used to make iron supports. Steel is a strong and durable material that can bear heavy loads. Depending on the size and type of hole, different thicknesses and types of steel sections may need to be used.

Installation of iron support:

Installation of iron support should be carried out by an experienced structural engineer. The process includes:

  • Dimensioning and marking the hole in the wall
  • Cutting a hole in the wall
  • Positioning and anchoring the supports and support beams
  • Welding of angles and connections between elements
  • Checking the stability and strength of the iron support

Important aspects:

  • It is important to obtain planning permission before starting any work on the wall.
  • Protective equipment such as goggles, gloves and a dust mask should be used when cutting the concrete wall.
  • The iron support must be designed and constructed in such a way that it can support the weight of the wall and prevent it from collapsing.
  • Once the installation of the iron support has been completed, it is important to check its stability and strength.

Conclusion: The iron support is an important element when cutting a hole in a concrete wall. A properly designed and installed iron support will ensure the stability of the wall and prevent it from collapsing.

Removal and disposal of debris after concrete cutting

Removal and disposal of construction debris after demolition and cutting work is essential. The material from demolition of load-bearing walls is considered a special type of waste that cannot be disposed of in normal municipal waste and requires specific management in accordance with applicable regulations.

When cutting concrete walls, it is necessary to allow for more cuts than just the perimeter of the opening. Walls shall be cut gradually, in sections, for reasons of safety and handling. A concrete block from the entire opening of the transition door would be too heavy (700-800 kg) and its removal would be problematic. Therefore, it is important to consider the actual extent of the cuts, not just the size of the required opening, when calculating the cost. For example: if we want to cut a standard door opening (2000 x 1000 cm) we have to calculate a 10 bm cut, even though logically we only have about 5-6 bm of cut. Then the concrete blocks do not weigh so much and can be easily removed from the apartment/house.

Cutting concrete panels requires expertise, experience and adherence to safety procedures. Therefore, it is recommended to entrust this work to qualified professionals or a company.

Caution: Demolition of partitions and cutting of concrete panels may affect the structural integrity of the building. A structural engineer must be consulted before work commences to assess the safety and stability of the building after the alterations have been made. In the case of apartment buildings, it is often necessary to consult and approve demolition work with the representatives of the apartment owners.
