Completed Projects Nationwide

Rapid Installation

The Geopier® system is known for its relatively quick installation process. This minimizes construction delays and speeds up project timelines without compromising quality.

Versatile Application 

The Geopier® system is versatile and adaptable to a variety of soil conditions, including those with low bearing capacity, high compressibility, or variable composition. It is suitable for a wide range of construction projects, from residential buildings to industrial facilities.


The materials and installation procedure of our technology directly translates into savings compared to traditional deep pile foundations. The value-added aspect is clearly seen in the performance of the Geopiers, which are able to control overall settlement and attain the required bearing capacities at a
fraction of the costs to traditional options.

How can we help you?

There are so many reasons why PGATech should be your solutions provider in your ground improvement needs:

Enhanced Safety

By mitigating risks associated with ground instability like soil liquefaction and such, PGATECH’s Ground Improvement Solutions contribute to the overall safety and longevity of the projects, protecting both assets and human lives.

Cost Savings

Utilizing our ground improvement solutions can result in substantial cost savings for your projects. By strengthening the existing soil, we minimize the need for expensive deep foundation systems or extensive soil replacement. This efficient approach not only lowers initial construction costs but also reduces long-term maintenance expenses, making your project more economical.

Environmental Sustainability

Our ground improvement services are designed with environmental sustainability in mind. By enhancing soil properties in situ, we reduce the need for extensive excavation and transportation of materials, thereby lowering the environmental impact.

Project Versatility and Customization

We offer a wide range of ground improvement solutions tailored to meet the specific needs of your project. Whether it’s soil compaction, grouting, soil stabilization, or other advanced techniques, our team of experts can customize the approach to address unique site conditions and project requirements. This versatility ensures that we can effectively tackle diverse ground challenges, delivering optimal results for every project.

Featured Project

Ground Improvement Works for a Storage Facility Project

The subsurface conditions consisting loose sands, soft clays, and a shallow water table indicated the potential for liquefaction. To address this, Prefabricated Vertical Drains (PVD) were installed to accelerate the consolidation of compressible clays. Additionally, 1,384 Geopier® positions were installed to provide settlement control, liquefaction mitigation, and provide foundation support with an enhanced area-wide bearing capacity.
