Tetra Tech Coffey’s ground improvement experts know how to deal with the design and construction verification of ground improvement measures on marginal land.
Weak and highly compressible or collapsible soils or liquefiable ground can create serious consequences for a project if they are not well-managed. Our ground improvement experts can correctly interpret a site’s geology and geotechnical conditions and identify compressible, liquefiable, or other weak soils prior to design. If weak or undesirable soils are encountered, we can develop the most appropriate, cost-effective ground improvement methods to ensure a successful project – always considering available time for the development.
