Drilled Shafts

Drilled shafts are often used to solve deep-seated slope stability problems.  When slope failure planes run deep the driving forces are high which require a reinforcing element with a high section modulus placed at a relatively close spacing.  Drilled shafts used for slope stability applications typically consist of 24 to 42 inch diameter reinforced concrete shafts.

Precast Concrete Piles

Precast Concrete Piles are displacement piles that are one of the most economical pile systems on a cost per lineal foot per load supported basis.

Ductile Iron Piles

Ductile Iron Piles (DIPs) are a pre-fabricated driven pile system utilizing high-strength ductile iron pipes that transfer the load from a footing or pile cap, or heavily-loaded slabs to a stiff soil or rock layer to control settlement of a structure.  DIPs can be designed for end-bearing or skin friction depending on the stratigraphy and loading conditions.
