Pushing Boundaries with High Capacity Helical Piles

Posted by Stephen Scott, EIT on Mar 29, 2021 8:30:00 AM

As the concepts and design of modern structures continue to evolve, so too must the deep foundation systems on which they are founded upon. With the help of modern technology and material science, structural boundaries continue to be pushed and economic considerations are causing a trend toward the increased use of high-capacity piles. In response to the demand, helical piles have expanded beyond light and medium loaded structures and have been engineered to support heavily loaded structures subjected to both compression and tension.

Helical Piles vs Concrete Drilled Shafts (Caissons)

Posted by Shawn Downey on Mar 2, 2021 4:39:03 PM

There are several solutions engineers and contractors can choose from when a deep foundation is required. With a deep foundation the structure’s load is transmitted to soils that are deeper in the ground. A deep foundation is used when a shallow foundation is not possible, not practical, or will not carry the load. Examples are weak, unstable, or expansive surface soils. Two popular options for deep foundations are helical piles and drilled shafts, also known as drilled piers or caissons.

Foundation Solutions for Environmentally Sensitive Areas

Posted by Intech Anchoring Systems on Sep 4, 2020 8:15:00 AM

A key benefit of helical piles is the ability to install them in environmentally sensitive areas. CHANCE helical piles are precisely engineered to create minimal disturbance to the soil itself during installation with the pitch and placement of the helices precisely calculated. Helical piles can also be installed using limited access installation equipment eliminating the need for damaging access roads and large equipment required for other foundation types.

Helical Pile Foundation Engineered to Support Hillside Boardwalk Trail

Posted by Walder Foundation Products on Aug 21, 2020 11:15:19 AM

Helical piles have been gaining notoriety as an ideal foundation solution for many types of trails, boardwalks, and walkways. The town of Ashland, Virginia sought a pedestrian and bicycle trail constructed to connect Carter Park to the existing Ashland trolley line trail. The trail is an easy half-mile walk along a very straight and level path. To connect Carter Park to the Ashland Trolley Line Park trail a boardwalk was needed over the steep embankment along Walder road. The Ashland Trolley Line Park Trail is a Greenway trail which is protected and managed for conservation and recreational purposes.

How To Build A Lasting Pool Foundation

Posted by Foundation Technologies, Inc. on Aug 4, 2020 9:15:00 AM

As with a foundation on a home, the foundation of a swimming pool can experience sinking due to unstable or poorly compacted soil. Ensuring a pool is constructed on a deep, lasting foundation will protect the owner investment and save them from costly future repairs. Whether you're a contractor building a backyard pool or an indoor aquatic center, starting on a firm foundation is key for the long-term success of any project, and there are a wide range of variables in the design process.

Engineered helical piles for lateral load capacity on ballistic barriers

Posted by Josh Lindberg on Jul 24, 2020 9:49:00 AM

Helical piles are an established solution for foundation underpinning, but their applications are as far-reaching as the creativity of an engineer. Helical piles are typically associated with gravity load - force pushing down on the pile. In the project below, helical piles are utilized to support lateral loads, including wind and seismic loads.

High Capacity Foundation Solutions for Difficult Site Conditions

Posted by CHANCE Foundation Solutions on Feb 11, 2020 10:13:00 AM

Traditional foundation methods can be tricky to implement when access is limited, overhead clearance is especially low, or soil conditions call for strict weight limitations. For instance, on swampy ground or low-quality soil, the machines needed to install conventional foundations cannot always operate safely or maneuver effectively.
