How Is Site Grading Performed?
Usually engineers ask for native clay or yellow clay to be installed around the perimeter of the foundation at a minimum slope of 5% away from the foundation. after this a tamper or a jumping jack should be used to compact the material properly.
What Is This Process Used For?
This is performed not just to level out the ground for a strong foundation but to make sure that the water flows in the right direction. The process needs to be done properly to prevent problems like basement flooding, damage of foundation and erosion. These problems usually happen when the drainage system has a flaw in it.
