cutting concrete? No reason to panic! With this comprehensive guide, we make you the expert for your next construction project.
Difficulty: Medium | Costs: from 15 euros | Workload: 10 - 30 minutes per cutting meter
Concrete is an extremely durable and versatile building material.
It consists of a mixture of cement, water and aggregates such as sand, gravel or stone.
This makes concrete very resistant to physical stress and environmental influences. However, these properties are also the reason why it is difficult to process and in particular to cut or saw.
1. The challenges of concrete cutting
Cutting concrete is a common task on construction and home improvement projects, but it's no easy task.
Here is where concrete is most commonly used after home construction:
- driveway for a house
- terrace foundation
- As a foundation for gazebos and tool sheds
- When subsequently laying plumbing and electrical lines.
- Cutting concrete slabs
- Openings for walls, doors and windows in concrete masonry.
2. The right tools for concrete cutting
There are various tools and machines that can be used to cut concrete.
These include angle grinders, concrete saws and corresponding diamond cutting discs for cutting concrete, as well as chemicals and concrete drills or concrete chisels.
Our tip: You don't have to invest in expensive machines or tools. Take what you already have on hand.
2.1 Cutting concrete with the concrete saw
Concrete saws are one of the most popular machines for cutting concrete.
A distinction is made between a wall saw or floor saw for concrete. Both types are more likely to be used in the professional field. They are particularly suitable for creating very large wall openings made of reinforced concrete.
2.2 Cutting concrete with the angle grinder
Everybody knows him. The good old angle grinder that everyone has at home.
Equipped with the right tools, the Flex is an excellent machine for cutting concrete. Fitted with a 125mm blade, the maximum cutting depth is approximately 4.5cm and is perfectly adequate for a range of applications.
Our experience: It is important to only cut the concrete with a diamond blade that is designed for working with concrete . Otherwise, the concrete disc will wear out too quickly or the material cannot be cut.
2.3 Cut through concrete with a hammer drill
Hammer drills are another way to cut through concrete.
Good to know: A hammer drill is actually intended for drilling extremely hard materials.
However, you can also get the result of cut concrete with a lot of holes next to each other.
Our Opinion: While not as effective as saws or the Flex, they are easier to carry and can be a lifesaver for small, precise "cuts".
The largest possible drilling diameter is recommended for this purpose, as otherwise the work can be quite lengthy, boring and exhausting.
3. The most common applications when cutting concrete
Cutting concrete, as we have learned, is a necessary chore in a variety of construction and renovation projects.
A list of the different concrete cutting methods:
3.1 Flexing reinforced concrete
Reinforced concrete is a type of concrete that is reinforced with steel bars or mesh to give it extra strength.
A concrete saw is typically used for reinforced concrete as it is capable of cutting through both concrete and steel.
With a little patience we have already been able to flex all the reinforced concrete.
Our experience: Please take regular cooling breaks to protect the diamond segments.
3.2 Cut concrete floor
Cutting concrete floors is a common task when installing new plumbing or preparing areas for tile or other flooring.
In our opinion, an angle grinder or a slot cutter is usually used for this.
3.3 Break up concrete as an alternative
In some cases, particularly larger projects, it may make sense to break up the concrete rather than cut it.
Tip: For refurbishments or complete renovations, chiseling out is the quickest and cheapest alternative for areas of more than 20 square meters.
For this purpose, jackhammers can be used, which break up the concrete with quick, powerful blows.
3.4 Wear safety goggles, earmuffs and a dust mask to protect yourself as much as possible
It is extremely important that you wear the correct protective gear while working on concrete projects.
- Safety goggles protect your eyes from flying concrete and dust.
- Earmuffs will help protect your hearing from the loud noise of the machines.
- A dust mask, on the other hand, protects you from inhaling concrete dust, which can be harmful to your health.
3.5 Precise marking of your cutting lines is the be-all and end-all when cutting concrete
Before you start cutting concrete, you should accurately measure and mark the area you want to cut. This will help you create accurate and clean cuts and avoid mistakes.
4. Conclusion - Cutting concrete can be done by anyone
Cutting concrete is a common and necessary activity in many construction and renovation projects.
With the right tools, knowledge, and safety precautions, you can cut concrete effectively and safely. Whether you use a concrete saw, angle grinder, or hammer drill depends on the size and type of project.
Remember to always wear the appropriate personal protective equipment and to accurately measure and mark the work area before beginning work.
