Deep Expertise in Deep Foundations
Deep foundations are crucial to ensuring the stability and longevity of structures bearing heavy loads or in challenging soil conditions. Backed by a world-class equipment fleet and industry-leading expertise, Kiewit Foundations ensures cost-effective solutions and expert execution for drilled shafts, micropiles, auger cast piles, driven piles and more.
Drilled Shafts
Drilled shafts (also called caissons, drilled piers or bored piles) are designed to provide a cost-effective and strong-performing deep foundation solution. From bridges to high rises and other large structures where heavy loads and lateral resistance are major factors, Kiewit Foundations ensures expert drilled shaft solutions and seamless execution.
Micropiles
For projects requiring deep foundations in tight spaces or low-overhead conditions, micropiles offer a highly adaptable solution. Installed using rotary or percussive drilling methods, these small-diameter, high-strength piles are reinforced with steel casing, high-strength central bar and cement grout.
