A percolation test is the best method to determine the suitability of the <br /> 6. soils. Please see the next section for percolation test results. Generally speaking, sandy non- <br /> cemented soils have much greater potential for percolation than fine-grained cemented soils. <br /> L <br /> L <br /> L 8 <br /> L '004 <br /> L <br />
