When engineers face loose sands, soft clays, or other weak soils, two common foundation solutions come to mind: displacement piles and CFA piles. Both systems have been used successfully in deep foundations for decades, but recent innovations, like Chance’s GroutForce™ Displacement Pile (GDP), are shifting the way we think about load capacity, installation efficiency, and overall project cost.  In this article, we’ll compare CFA piles and displacement piles, highlight their s

In construction, the strength of any structure ultimately depends on one critical factor: what lies beneath it. While superstructures often receive the most visual attention, it is the performance of the foundation system that governs long-term stability, serviceability, and safety. Subsurface conditions, however, are rarely uniform. Variability in soil composition, moisture content, density, and groundwater levels can significantly impact how loads are transferred and resist

When it comes to building on unstable or challenging soil conditions, the foundation is everything. That’s where helical piers, also known as helical piles or screw piles, come in. These innovative, screw-shaped foundation elements are revolutionizing how we stabilize structures and support loads, offering an efficient, clean, and cost-effective alternative to traditional foundation systems.
