Weak, compressible soils may require structural elements that transfer loads to underlying competent soils or rock, specifically deep foundations (also known as heavy foundations). Keller can provide the optimal deep foundation solution on an open site or inside an existing structure.
- Support new or existing structures
- Support compressive, tensile, or lateral loads
- Support static and seismic loads
Deep foundations are generally connected to the structure and can be installed before construction or as underpinning elements for existing structures. They can be driven elements of timber, steel, or concrete or constructed in the ground by drilling a cased or open hole and filling it with reinforced concrete. The load can be transferred to the bearing stratum through end bearing and/or side friction. Grouting techniques can be used to construct or enhance the load transfer element.
Having experience with the full range of deep foundation techniques, we can provide the most cost-efficient and technically appropriate solution.
