Geopier® Ground Improvement: Scalable, Tailored Solutions

We are dedicated to providing industry-leading ground improvement solutions to address poor soil conditions and help ensure safe and resilient buildings/infrastructure across the Northeast. Each project is unique, with varying demands across residential, commercial, and industrial sectors requiring flexible and adaptable solutions. Geopier® Ground Improvement systems are exceptional for their scalability and provide tailored solutions to meet project-specific needs. From small-scale projects (such as 3,000 SF footprint gas stations) to larger commercial or industrial developments (such as massive >200,000 SF footprint distribution warehouses), we look forward to supporting your project needs from initial feasibility and throughout the estimating and construction process.

With Geopier GeoConcrete® Column (GCC) Rigid Inclusions and Rammed Aggregate Pier® (RAP) elements, HELCIAL delivers ground improvement solutions to increase soil bearing capacity and control settlement in extremely poor soil conditions. These solutions offer a cost-effective alternative to traditional deep foundations (piles) and are ideal for a wide range of applications.

Note in the illustration how the (left) mat loaded to the project-specified 5 ksf maximum allowable soil bearing pressure induces more stress beyond the “moderately compressible” upper zone soils into the “more compressible” lower zone soils. This simplified soil profile is quite representative of many typical soil profiles in the Northeast. When settlements are calculated for these identically sized foundations, the effect of the increased stress on the “more compressible” layer is often substantial. In many cases, the increased settlement from this simplified loading assumption drives the project from a shallower, more cost-effective ground improvement solution and onto more expensive solutions like deeper ground improvement or deep foundations (piles). In summary, using allowable soil bearing pressures to calculate settlement can yield misleading conclusions regarding foundation support viability and/or lead to Owner cost premiums.

Commercial (Warehouse Addition)

Geopier Rammed Aggregate Pier ground improvement allowed for conventional shallow footing and slab-on-grade construction and helped expedite the construction schedule. The RAP elements were designed to limit the total and differential settlement to less than 1 inch and ½ inch respectively, and provided a maximum allowable footing bearing pressure of five (5) kips per square foot.
