- Bearing piles are driven into the ground until a hard stratum is reached.
- Friction piles are used when the soil is soft and there are no hard strata available.
What is driven piling?
A driven pile is a relatively long, slender column, provided to offer support or to resist forces, made of preformed material having a predetermined shape and size that can be physically inspected prior to and during installation, which is installed by impact hammering, vibrating or pushing into the earth.
What is the purpose of pilings?
Piles are an essential component of many construction projects because they can provide a strong, sturdy foundation for a structure regardless of soil quality or harsh environment.

Typically, 8” x 8” pilings are placed at least 8 feet in the ground (16 feet in the ground for homes closer to the ocean). The pilings are set by injecting water into the ground and are held in place by the pressure of the sand. Older homes are often resting on 6” pilings.
Is pile driving expensive?
However, it’s an expensive option because of the various on-site processes involved. Friction piles could need temporary casings, excavation, management of the spoil, concrete pouring, rebar cage production, insertion etc, plus all of the associated equipment required for handling each process.
What are the different piling techniques?
The load therefore bypasses the weak layer and is safely transferred to the strong layer.

How deep should piles be driven?
Usual depths for concrete precast piles range from a few meters to around 30 m, but under special circumstances piles have been driven down to 150 m! Steel circular piles in offshore works can go much deeper.
