How to Cut Concrete Horizontally

In this blog post, we’ll provide some helpful tips on how to efficiently cut through concrete no matter what the size or width is — from small sidewalk patches all the way up to large roadways and even foundation walls. So read on for more advice about completing horizontal cuts with precision for your next DIY project!

Is It Difficult to Cut Concrete Horizontally?

When it comes to cutting concrete horizontally, the difficulty depends on the size of the surface. For small patches or slabs of concrete like those that are often used for driveways and sidewalks, it’s relatively easy to use hand tools such as a saw to achieve a smooth edge. However, if you’re dealing with larger surfaces like those used for foundations or roads, then it’s best to use power tools such as a concrete saw.

In either case, the most important thing is to make sure that you have all of the necessary safety gear and equipment before beginning. This includes eye protection, hearing protection, gloves, and even respirators if you’re dealing with especially thick concrete.

Things to Consider Before Cutting Concrete Horizontally

1. Type of Concrete

Before you begin cutting concrete horizontally, there are a few things that you should keep in mind. Firstly, you need to know the type of concrete and what sort of reinforcements it may contain. Reinforcements such as rebar or mesh can make it more difficult to cut through and may require additional precautions like using special blades.

2. Layout of the Cut

You also need to take into consideration the layout of the cut that you’re going to make. If it’s a straight line, then it should be relatively easy to achieve with any saw or cutting tool. However, if there are curves or angles involved, then you may need an experienced eye and a steady hand to make sure that everything is cut properly.

3. Gather Tools

Lastly, you need to think about the tools that you’re going to use for cutting concrete horizontally. For smaller jobs, a masonry saw with a diamond blade will be sufficient — just remember to wear all proper safety gear. For larger surfaces, you’ll likely need a walk-behind saw or even a concrete cutting machine.

Once you have the right tools, it’s all just a matter of making sure that you take your time and follow the proper safety precautions. This way, you can get great results without having any issues with your concrete project!

Required Items

Cutting concrete horizontally requires a few materials and tools.

  • A diamond blade is needed to make the cut
  • Safety glasses and gloves.
  • Cutting indoors due to ventilation requirements
  • Dust mask or respirator

10 Ways How to Cut Concrete Horizontally

1. Mark the Line

Mark the cutting line on the concrete with a marker or chalk. You also need to double-check the line and make any necessary adjustments. While marking the line, it’s important to keep in mind that the cut should be made at least 6 to 8 inches away from the edges of the slab.

2. Score the Surface

To score the surface, use a masonry saw equipped with a diamond blade and make multiple passes along the marked line. Make sure that you wear safety glasses and gloves to protect yourself against any flying debris.

3. Use a Hammer and Chisel

Once the surface is scored, use a hammer and chisel to break off the edges of concrete around the cut line. You can also use a masonry drill with a core bit to make deeper cuts if necessary. Chisel and hammer are best when dealing with small concrete cuts.

4. Use a Circular Saw

For larger surfaces, you can use a circular saw to cut the concrete along the marked line. When using this tool, it’s important to make sure that you have chosen an appropriate blade for cutting through concrete and wear safety glasses and gloves.

5. Use a Walk-Behind Saw

For large jobs or when cutting deeply into concrete, you may need to use a walk-behind saw. This type of saw is equipped with diamond blades and can make precise cuts up to 12 inches deep. Again, wear safety glasses and gloves to protect yourself from flying debris.

6. Use a Wet Saw

A wet saw is specifically designed to cut through concrete and can make very even and precise cuts. The blade of the saw is submerged in water, which cools the diamond blades, reducing wear and tear on the blade itself. When using a wet saw, it’s important to follow all safety instructions and wear the proper safety gear.

7. Use a Concrete Cutting Machine

For complex concrete cutting jobs, you may need to use a concrete cutting machine. These machines are designed for precise cutting and can cut through reinforced concrete up to 18 inches deep. It’s important that you only operate this type of equipment after receiving proper training and instruction.

8. Use an Angle Grinder

An angle grinder is a versatile tool, often used for grinding and polishing. However, you can also use it to make straight cuts in concrete. The diamond blade should be of the correct size for the job, and you must wear safety glasses and gloves when using this tool.

9. Use a Chalk Line

For marking the cutting line on the concrete, you can use a chalk line instead of a marker or chalk. A chalk line is much easier to wipe away afterward, and it will stay in place better than regular chalk. This is especially useful for complex cuts that require precise lines.

10. Clean Up

When you’re finished cutting the concrete, it’s important to clean up the area and dispose of any debris properly. This can help prevent any accidents or injuries that may occur due to the dust or pieces of concrete left behind.

By following these steps, you should be able to cut your concrete with ease and precision. Remember to always use the right tool for the job and wear safety glasses and gloves when operating any type of saw or grinder. With the proper preparation, you can make clean horizontal cuts in your concrete with ease.

6 Safety Measures to Follow

When it comes to cutting concrete horizontally, the process can be quite dangerous. There are a few safety measures one should take to ensure the job is done safely and efficiently. Here are 8 essential safety precautions to follow when carrying out horizontal concrete cutting:

1. Wear protective equipment. Always wear protective equipment such as safety glasses, ear plugs, and a dust mask when cutting concrete. It will always be a good idea to put on some form of respiratory protection to ensure that no airborne particles enter your lungs.

2. Keep the environment clean. During the cutting process, dust and debris can fly around and disperse in the air. Make sure you have placed wet towels or blankets beneath the saw so as to reduce dust scattering around. You should also remember to keep the place you are cutting in well-ventilated.

3. Make sure that no one is standing near the work area. It is always best to keep bystanders as far away as possible when sawing concrete horizontally, as pieces of debris may fly out and hurt someone if they are too close.

4. Use the right tool for the job. Make sure you use the correct saw for your job in order to get the desired result. Different types of concrete can require different saws and blades, so make sure you select the appropriate one before starting.

5. Check for underground wires or pipes. It is important to always check for any underground power lines or pipes before cutting horizontally. If these objects are present, you need to contact a professional as soon as possible in order to find the safest way of avoiding them when sawing.

6. Take your time and be patient. It is important to take your time when cutting concrete horizontally, as rushing could result in mistakes or injuries. Take the necessary precautions and take your time to finish the job safely and correctly.

Following these safety measures when cutting concrete horizontally will ensure that the job is done safely and efficiently.


Cutting concrete horizontally is not a difficult task as long as the right precautions and preparations are taken. Make sure to use safety goggles, gloves, and appropriate ear protection when working with tools. Take measurements to ensure precise cuts, choose an abrasive diamond disc for electric grinders for efficient precision cutting, and mark the line of the cut with chalk first—all these steps on how to cut concrete horizontally will help you achieve success.

With proper care, cutting concrete horizontally can be relatively hassle-free. Not only that, but it can also look ultra-modern with meticulous accuracy. So give it a shot—no need to break down a wall or hire professional contractors–you got this!
