How to Use a Laser Level for Grading

It’s critical to get the grading of a slope or surface right the first time. You don’t want to have to go back and correct your errors afterwards. That is why utilizing a laser level is such an efficient approach to complete the task fast and accurately.

Laser levels are simple to use and can assist you in achieving excellent results every time. In this post, we’ll go over the fundamentals of grading with a laser level. We’ll also give you some pointers on how to make the most of your laser level. So let’s get this party started!

What Is a Laser Level?

When grading a surface, a laser level comes in helpful. It emits a laser beam that can be readily aligned with your chosen plane, allowing you to achieve flawlessly level results every time.

There are two types of laser levels: manual and automatic. A manual laser level requires you to keep it in place and adjust it as needed, whereas an automatic (or self-balancing) laser level does all of the work for you.

Before you begin grading, make sure the laser level is properly calibrated. This ensures precision and prevents errors.

How Does a Laser Level Work?

You’re undoubtedly curious about how a laser level works. In essence, it emits a laser beam that is reflected off a leveled surface and returned to the instrument. This produces a visual reference that can be seen with the naked eye or through a digital display.

Using this information, you can grade your landscape by aligning it with a specified surface, such as a stake in the ground. It’s quite exact and ensures that your grading is consistent from one end of the landscape to the other.

The Different Types of Laser Levels

There are various sorts of laser levels, and it is critical to understand which one is appropriate for the work at hand. Here’s a quick breakdown:

  • Manual Level:

The manual level is, well, manual. To guarantee that the level is pointed in the appropriate direction, you must manually adjust it.

  • Automatic Level:

You don’t have to worry about getting the automatic level lined up correctly because it will self-correct.

  • Rotary Laser Level:

A rotating laser beam is emitted by the rotary laser level, which can be utilized for long-distance leveling and alignment.

  • Line Laser Level:

The line laser level projects a horizontal or vertical line onto surfaces, which can be useful for marking off dimensions or determining levelness.

So, which one do you recommend for grading? It is entirely dependent on the project at hand. However, for larger jobs, a rotary laser level is preferable, while a line laser level is preferable for minor work.

How to Use a Laser Level for Grading

Now that you’ve determined the appropriate level for the job, let’s get you up to speed on how to complete it. Here’s how to grade with a laser level:

  • First, locate a level surface on which to work.
  • Next, place your laser level on the surface. Check that it is stable and will not move while you are working.
  • Adjust the laser level’s height until the beam is pointing straight down at the ground.
  • After aligning the beam, use a spirit level or a carpenter’s level to ensure that the surface is level.
  • Finally, begin grading your surface by following the laser level’s lines.

Tips for Using a Laser Level

Here are a few pointers for using a laser level to achieve consistent grading:

  • Ensure that the surface you are grading is level. This is the most critical step—if your surface isn’t level, your laser level won’t work properly.
  • Before you begin, calibrate your laser level. This guarantees that the beam is pointing straight ahead.
  • Check that nothing is in the way of the beam. If something is blocking the beam, your measurements may be thrown off.
  • If possible, use a tripod. This will aid in the stability and consistency of your laser level.
  • Take your time and remember to measure twice and cut once. This old adage is especially relevant when it comes to grading—double-check your measures to avoid costly mistakes.

FAQs About Using a Laser Level

Undoubtedly, you will have some concerns about the usage of laser levels. Here are some of the most often asked questions and their responses.

Can I Use Laser Levels During the Day?

There are no laser levels available with full vision outside, in direct sunlight, beyond a few meters. As a result, the laser beam may be invisible in broad daylight. Nonetheless, fixed dot lasers have a visual range of 10m; beyond this, consider utilizing a reflecting target and using laser glasses to extend the range.

Is the Laser Light Harmful to My Eyes?

Yes, it can be! The most common concern connected with lasers and vision is flash blindness.

This visual impairment develops when the eyes are exposed to a very bright light flash. It may be either temporary or permanent. If the retina is permanently damaged by laser use, it could result in permanent blindness. Therefore, always use caution when using laser levels to safeguard your eyes.

Is a Laser Level’s Accuracy Rating Important?

The answer is dependent on the task you are attempting to complete. Nevertheless, the most important factor is that the precision required for operating the laser level is met. Lasers with a wavelength range of 1mm to 4mm in 20m are adequate for outdoor long-range operations. However, in a highly specialized technical situation, laser tolerance becomes critical.


You can use your laser level to grade your land precisely every time if you follow these basic guidelines. Simply take your time and be patient when setting up your level. Once you’ve mastered it, you’ll be able to finish your grading project swiftly and efficiently – and with flawless results.

Are you ready to give grading using a laser level a shot? You’ll be on your way to flawless land grading in no time if you follow these simple instructions!
