Driven piles are installed to accommodate compression, tension or lateral loads. Piles can be selected to meet the specific needs of your site conditions or budget. Camden Foundation Technologies piles are installed to established criteria. Because they are normally driven to a blow count to assure the desired minimum capacity, pile lengths may vary when subsoil conditions are not uniform. In corrosive environments, coatings and or additives can be used to nullify the effects of corrosion thereby lengthening the service life of a structure.
The design, installation and quality assurance that are a part of each driven pile combine to eliminate any guesswork and produce a known, reliable, and cost effective product which can accommodate a wide variety of situations. Driven piles consist of natural materials or pre-manufactured shapes built to precise tolerances utilizing high-strength materials and reliable quality control. Their quality is consistent from the first pile to the last and can be seen and verified prior to installation.
Camden Foundation Technologies equipment and installation methods are time-tested and well proven. Recording the blow count versus depth during pile driving easily documents pile installation. You know what you have at the completion of driving because they have a measurable capacity providing assurance that the piles meet the project requirements. Driven piles have vastly superior structural strength because they have high lateral and bending resistances for their entire length.
Driven piles are usually the most cost effective foundation solution. There are no hidden extra costs or added expenses for site clean-up. Capacity per pile or pile length can be easily calculated to provide exactly the required capacity (including safety factors). As an additional benefit, driven piles often gain capacity after installation.
No Soil Spoils, No Vibration, No Heavy Equipment
Unlike the equipment and processes required to install other deep foundations, helix piles do not create any soil spoils that must be removed. The installation equipment is small, easily maneuverable and does not create vibrations. These features and benefits make Helix Foundations an efficient and affordable solution for job sites with restrictive access or environmentally sensitive conditions.
What is a Helix Foundation System and How Does it Work?
Helix foundations are an economical deep foundation alternative to wood and steel shell driven piles or concrete caissons. They are also a sensible and often more reliable alternative to shallow footings and reinforced mat foundations. In addition, Helix Foundations are excellent for supporting new residential buildings, additions, retaining walls and boardwalks. The torque required to install a helix pile is a good indication of the strength, density and bearing capacity of the soil at the depth of the helix cutting blades. Once the helix pile is successfully installed, it serves as a deep foundation support with a capacity of up to 25 tons.
Hot dipped galvanized is standard on all Helix Foundation products. This process provides the highest degree of corrosion protection possible from a coating process. In soils with moderate-to-high corrosive levels, helix piles will last more than 100 years.
On most projects, helical piling can be installed quicker than traditional concrete caissons, or steel shell and wood piling. They can be installed in any kind of weather and are not subject to delay from groundwater and caving soil. The speed of installation alone often results in significant cost savings in comparison to any other foundation type.
Helix foundation systems are sometimes referred to as helix piles, helical anchors, helicals, screw piles or earth anchors. Helix piles are screwed into the ground using a torque motor. The lead or first section is designed with one or more helix blade(s) welded to the pier's shaft, and each blade cuts its way downward into the soil as the pier is rotated by the motor. Additional sections called extensions are added to the lead section until the desire depth is achieved.
