This technique involves creating piles by displacing rather than removing soil, beneficial in Hawaii’s diverse soil conditions. It has less environmental impact, reduces noise, and ideal for urban and coastal areas.

Drilled shafts, also known as drilled piers, caissons, or bored piles, are deep foundation solutions used in various construction projects, including buildings, bridges, and towers, due to their strength and durability. Drilled are particularly effective in transferring structural loads through weak soils to stronger, more competent strata deep below the surface.

Driven piles, a foundational element in geotechnical engineering, are long, slender columns driven deep into the ground to support structures. Widely used in various settings, including coastal regions like Hawaii, they provide stability in soft or loose soils and are ideal for resisting coastal erosion and wave forces. This method ensures robust, reliable support for buildings, bridges, piers, and other structures in challenging environments.

Micropiles are a type of deep foundation used to transfer structural loads through weak soils to stronger layers deep underground. They are small-diameter, typically less than 12 inches, drilled and grouted piles with a high-strength steel core. Micropiles are versatile and effective for foundation support and underpinning in challenging ground conditions, often used in urban environments or where space or access is limited. Their installation causes minimal vibration and noise, making them a preferred choice for sensitive sites.

Soldier pile walls, also known as soldier beams, are retention systems used in deep excavations or construction projects. They consist of vertical steel beams (piles) driven into the ground at regular intervals. Between these beams, wood, concrete, or steel panels are inserted to hold back the earth, creating a stable wall for excavation or construction. This method is widely used for its cost-effectiveness, adaptability to various soil conditions, and efficiency in managing deep excavations.
