A field is literally a bare canvas. A field has so many different possibilities for its future. It can be turned into pasture or farm land, it can be turned into a beautifully manicured park, and it can even be turned into the site of a home with enough time and effort. For many, a field is the first step towards their final goal. However, while some fields are so obviously sloped, any grassy fields can be quite deceptive. Luckily, one of the best tools that can help you turn that field into whatever you can imagine can also help you create a level field as well – the laser level.
Unlike areas that are already under construction, using a laser level on a field can be difficult. Not only can the thin red or green laser be difficult to see against the green grass, but detecting the actual grade of a field can be problematic due to the grass.
No matter what you are intending to build, the first step you should take is to get rid of the grass. This could mean digging up the entire field or simply cutting the tall grass down. By doing this, you can also discover if or how bad your field needs to be laser leveled. If there are tons of dips or uneven areas, it won’t be suitable for any purpose. Even if you are using it for something as simple as pasture land, if you leave tons of dips in your grazing land, there is a fair chance your animals can hurt themselves. If you are using it to build or grow crops, uneven areas also mean pooling water and potentially uneven foundations. This means that even small flaws need to be fixed, and laser levels can help you find those flaws.
Once you have removed or cut the grass, you can start grading the land by setting up the laser level on its tripod and positioning a laser detector at the two furthest corners. You want to position the laser level so that it is diagonal from the laser detector to get the most sweeping reading. For this, you can use two laser detectors or you can just use one and move it.
Regardless of how many laser detectors you have, once your detector picks up the beam diagonal across the field, you can begin to take measurements from the beam down to the ground. If the measurements differ by more than a fraction of an inch, you will need to add or remove soil in the area to even out the ground. However, in a field, you need to be very careful with your measurements since the grass itself can throw off the numbers. It is for this reason that unless you are dead set on keeping the grass that is already in the field, it is best to just remove it so you can truly see how much you need to re-grade the land.
