New Construction? Deep Foundation Support
Helical piles, also known as steel helical torque anchors at Earth Contact Products, are designed to eliminate shifting soil specifically in an unstable turf. Foundations are subject to soil conditions that are in constant flux because of weather patterns and ground penetration. During the new construction process, professional engineers prefer American made steel helical piles for projects because they improve the structural integrity of foundations for years to come.
New Construction Installation Process – A Smart Choice
Because ECP steel helical torque anchors can be installed prior to the start of foundation construction, this product is a smart choice for the engineering community. Construction engineers are able to negate the effects of adjusting soil conditions in light of the pre-installation process. The anchors are hydraulically advanced into the ground to a predetermined depth based on soil data and by measuring torque during installation. In fact, “the amount of torque required to install a helical anchor relates to its installed ultimate capacity.” Then, the piles are installed at intervals between the footing forms and tie into the steel grid-work prior to pouring concrete.
Helical Torque Anchor Features
There are several advantages to using helical torque anchors in new constructions. The individual features of this particular product include installation times, structural capacity, and cost. Additionally, construction crews are able to install helical torques in areas of limited access and can be installed with little to no vibration. Check out more features of this beneficial product:
