Structural pipe piling is most frequently used in deep foundations and marine applications. Its stiffness, load-bearing capacity and bending resistance make it ideal for use in the construction of buildings, structures, wharfs, bulkheads and quay walls. The large surface area of pipe piles allows them to offer substantial frictional load resistance in deep foundations as well as point bearing properties.
For over two thousand years, timber piles have been used for shoring, foundations, docks, piers and more. Not only can this material satisfy the load capacities of most piling projects, timber piles can also save over 50% of the material costs when compared to other piling products.
Timber piling is an extremely viable piling option. Manufactured from an abundant natural and renewable resource, the natural taper of round timber piles increases friction capacity. They are resistant to acidic soils, unaffected by stray electrical currents, and do not require corrosion protection. Timber piles are easily cut to length with a simple chainsaw and use only EPA-registered preservatives. One of the key benefits of timber piles is, when properly preserved and caped with concrete, they can last more than one hundred years.
PRECAST CONCRETE PILES
Precast, prestressed concrete piles are often the preferred choice for durable and economical foundations, especially in marine environments due to their excellent versatility and resistance to corrosion.
Precast concrete piles are prefabricated, high-strength, prestressed concrete columns, impact-driven into the soil by means of an adjustable hydraulic or diesel hammer. These piles are available in various cross-sectional shapes, such as circular, octagonal or square.
H-Piles are designed for deep foundation applications. These piles are designed to transfer structural loads away from surface soils, which do not have the mechanical properties to support large buildings, to deeper bearing strata soils. The H-pile shape is the most effective to transfer load bearing through the pile to the tip. H-piles are most commonly used in dense soils or rock where no piling system is better for offering pile resistance at the tip for point bearing capacity.
H-Piles are also commonly used for "soldier beam and lagging" construction in braced excavations such as building and subway foundations.
