Geopier Firması 1989 yılında, oturmaya hassas yapıların desteklenmesi amacıyla verimli ve ekonomik bir Orta Derinlikte Temel çözümü olan orijinal Geopier Sistemi’ni geliştirmiştir.
The original Geopier® system was developed in 1989 as an efficient and cost-effective Intermediate Foundation® solution for the support of settlement sensitive structures. Today, the patented Geopier GP3™ system uses replacement Rammed Aggregate Pier® (RAP) elements to reinforce good to poor soils, including soft to stiff clay and silt, loose to dense sand, organic silt and peat, and variable, uncontrolled fill. The GP3™ system allows for visible inspection of the spoils, and the opportunity to address changing ground conditions as they happen. It is an effective replacement for massive over-excavation and replacement or deep foundations, including driven piles, drilled shafts or auger cast-in-place piles.
Geopier systems have become preferred replacements for massive over-excavation and replacement or deep foundations, including driven piles, drilled shafts or augered cast-in-place piles. Local Geopier engineers and representatives work with you and your specific soil conditions and loads to engineer a project-specific practical solution to improve your ground.

The Construction Process
The unique installation process utilizes pre-augering and vertical impact ramming energy to construct RAP elements, which exhibit unsurpassed strength and stiffness. RAP solutions are designed to provide superior total and differential settlement control and increased bearing support to meet project requirements.
1. The process first involves drilling a cavity. Drill depths normally range from about 1.5m to 10m, depending on design requirements. Pre-drilling allows you to see the soil between the borings, ensuring that the piers are engineered to reinforce the right soils.
2. Layers of aggregate are then introduced into the drilled cavity in thin lifts. A patented beveled tamper rams each layer of aggregate using vertical impact ramming energy, resulting in superior strength and stiffness. The ramming action densifies aggregate vertically and forces aggregate laterally into cavity sidewalls. This results in excellent coupling with surrounding soils and reliable settlement control.
3. Following installation, RAP elements support shallow foundations, floor slabs and tank pads and reinforce slopes and embankments. The footing stresses are attracted to the stiff RAP elements, resulting in engineered settlement control.
Strong and Stiff
Vertical impact ramming results in high density and high strength RAP elements providing superior support capacity, increased bearing pressure up to 480 kPa and excellent settlement control.
Thousands of structures are currently supported-proven experience that ensures high levels of performance and reliability.
Often results in 20% to 50% savings compared to traditional deep foundations.
Rapid installation process means shorter construction schedules.
Superior on-site quality control is maintained through observing, inspecting and testing the system, including visual spoil observation and full-scale modulus load tests.
Projects are engineered by Sentez Insaat Engineers and approved by Geopier Foundation Compnay.
