Driven piles are typically long slender colums made from timber steel or concrete hammered into the ground with an hydraulic impact hammer. Their quality is consistent from the first pile to the last and can be seen and verified prior to installation.
The design, installation and quality assurance that are a part of each driven pile combine to eliminate guesswork and produce a known, reliable and cost effective product that can accommodate a wide variety of subsurface conditions.
Driven piles maintain their shape during installation. They do not bulge in soft soil conditions and are typically not susceptible to damage from the installation of subsequent piles.
Driven piles are usually the most cost effective deep foundation solution. You pay only for what you need. There are no hidden extra costs or added expenses for site clean-up. The correct material selection and pile capacity for each project prevents unnecessary expenses.
Pile driving equipment and installation methods are time-tested and well proven.
Southern Piling Works can easily verify pile capacity by either static or dynamic pile testing. Capacity per pile or pile length can be optimized to provide exactly the required capacity (including safety factors) to minimize foundation costs. Testing also eliminates the uncertainty of bearing capacity estimates based on static analysis.
As an additional benefit, driven piles often gain capacity after installation. Shaft soil strength usually increases with time after pile installation is complete to provide additional load capacity.
