Before a structure or building can be constructed, geotechnical engineers conduct environmental site assessments on the land where the construction will take place. These assessments include soil tests in the areas proposed for development. The engineers examine soil samples to learn about the underground composition of the soils in the area, and make predictions about the long-term effects the soil at the site might have on the walls, foundation, septic system or any other components of the proposed structure. Some soils, such as clays, have a tendency to shrink and swell when their water content changes. This expansive property can put pressure on structure and foundation walls and cause them damage. Other soils are poor at settling or sinking under weight, causing uneven ground. Foundations that are built on these soils are at risk for cracking or bending.
