RAMMED AGGREGATE PIER^®

Foundation Systems are:

• RAMMED. Vertically Rammed + Heavy Crowd Force are the keys to providing unmatched strength and stiffness.
• STRONG. Impact hammer ramming of thin lifts of rock results in higher density and higher strength that increases bearing capacity. Resists lateral and uplift forces caused by earthquakes.
• HIGH STIFFNESS. Heavy vertical crowd plus ramming thin lifts of rock results in high RAP stiffness for reliable settlement control. Custom designed for every job site condition to get optimum and reliable foundation support.
• PROVEN. Over a decade of performance in California. Over 2,000 projects supported in more than 40 states & 10 countries ensures you are selecting a reliable and effective foundation-support solution.
• ECONOMICAL. Cost savings is often 20% or more
  versus driven piles and overexcavate/replace.
• FAST. Rapid installation process = shorter construction schedules. Install 30 to 50 RAPs per day – it is quick!
• SAFE. Design-build customer service reduces your budget risk by giving you a complete proven solution on a lump sum basis. Designed by California Registered Professional Engineers with over 30 years of combined foundation experience.
• ECO-FRIENDLY. Use recycled concrete/aggregate where available and get points toward LEED^TM certification.

RAP Estimating and Design at Farrell

California registered Civil, Geotechnical and Structural Engineers at Farrell can assist you with your tough soil site, foundation, MSE wall, or landslide.

Using RAPs allows the design and construction of cost effective conventional shallow footings. RAPs are used for several applications where improved soil is required.

Rammed Aggregate Piers improve soil by stiffening and prestressing soil before foundation loads are applied. Geopier RAPs are typically compacted to greater than 100% of the ASTM D1557 modified proctor. Please review some of the information below for more on Geopier and Impact RAPs .
