Soil Mix Walls
Soil mixing improves the engineering properties of soil by injecting cementitious grout and blending the materials in-Situ. Soil mix walls are constructed by overlapping elements of soil mixed ground, and inserting structural piles for reinforcing.

Diaphragm Walls Secant Pile Walls Internal Bracing Soil …
Overlapped drilled piles create a continuous rigid support and cut-off wall before start of excavation. Secant piling is a robust, rigid system which can be used to construct combined earth retention and groundwater cut-off walls. The continuous wall is constructed by drilling overlapped concrete piles with diameter typically between 2 and 4 feet.

How Sonic Drilling Works
When the resonant Sonic energy coincides with the natural frequency of the drill string, resonance occurs. This results in the maximum amount of energy being delivered to the face. At the same time, friction of the soil immediately adjacent to the entire drill string is substantially minimized, resulting in fast penetration rates.
