Rammed Aggregate Piers

Rammed Aggregate Piers (RAP) are a foundation technique that improves soil stability by inserting columns of compacted aggregate material into the ground. Heavy equipment places and compresses loose gravel or crushed stone in deep shafts, creating dense columns that reinforce weak or unstable soils. These piers distribute loads more evenly, providing a strong support for structures like buildings and bridges. RAP offers a quick, minimally invasive, and cost-effective alternative to traditional deep foundations, especially useful in areas with poor soil conditions, reducing settlement risks and increasing overall foundation stability.
