Twenty percent of car accidents happen in parking lots. Many of these are not the business’s fault. You can, however, prevent a fair amount of them with a high-quality parking lot.
The first step to getting this is to ensure the proper grading of your lot. To do that, you first need to learn what grading is. Read on to get started with this knowledge by learning the difference between rough grading vs fine grading.
What Is Grading?
Grading refers to the construction process where workers change the slope of a piece of land. Usually, this involves making the land uniformly smooth and flat.
There are plenty of different processes, however. Business owners may want to add a slope to their property that directs water away from vulnerable areas. Grading can also be a major step in creating attractive landscaping features.
What Is Rough Grading vs Fine Grading?
Rough and fine grading are two phases of grading. Usually, rough grading happens first, and fine grading follows after. Most of the differences between the two involve how roughly workers work the soil.
How Rough Grading Works
When workers rough grade a piece of land, they shift large amounts of soil around to form the majority of the slope. This is usually done with heavy equipment such as excavators. Workers may also use laser measuring tools or other kinds to make certain that the slopes are at the correct angle.
The workers must create the right slopes. If they don’t, the land could flood due to drainage problems.
How Fine Grading Works
Workers performing a fine grading process are more concerned with making the land smooth and ready for its intended purpose. This can involve shaping the land a bit. If so, workers will only work with the top two inches of soil at most.
Mostly, though, fine grading involves removing debris that makes the surface uneven, such as rock, and adding an appropriate type of topsoil. What kind of topsoil a worker uses for fine grading depends on the final purpose of the land. For example, more plant-nutritious topsoil may be used for a lawn and a regular one for paving.
Why Is Grading Important for Paving?
The best parking lot is a uniformly smooth one. This will prevent your business’s customers from damaging their cars or tripping over divots or bumps. It’s also important that water drains well so that your customers can comfortably navigate the lot without getting their feet wet.
This isn’t possible without effective rough and fine grading.
