High shrinkage soil
WebThe Interpretive information associates with a soil map also addresses shrink – swell. The map units are rated for their shrink – swell potential, generally low, moderate, high or very high. Current building code required the building plan to address the problem if the soil map for the project area shows a rating of “moderate” or higher. WebAug 26, 2024 · Expansive clay soils are high shrinkage soils that have low bearing capacity. So an effort is needed to reduce the nature of its swelling. One effort that can be done is the method of soil stabilization, where the soil is mixed with materials that can reduce soil swelling and increase the shear strength of the soil.
