Helical Piling Applications

Helical piling have been used for a wide variety of applications throughout the construction industry. Compared to concrete, driven or auger cast piling, helical piling offer significant savings in manpower, equipment and materials.

Helical piling can be installed and the load applied immediately - no additional excavation and form work is necessary. Helical piling are a dry construction method - water for augering or concrete is eliminated. Because equipment to install helical piling is small and mobile, they are ideal for areas of restricted access.

Some typical applications for helical piling are:

• Refinery Vessels
• Piping Manifolds
• Sound walls
• Pipe bridges
• Solar Panels
• Board walks
• Equipment slabs
• Electric TransmissionTowers
• Building slab repairs
• Building foundations
• Street light foundations
• Shoring for excavations
• Pipe racks and modules
• Valves and scraper traps
• Tank foundations and ring walls

Remember:  helical piling can be used anywhere auger cast, steel, wood or concrete piling are being considered.

Helical Piling Advantages

Helical piling offer many attractive advantages to the engineer, owner and contractor. Whether on a green field project or an existing facility expansion or retrofit, helical piling can provide significant savings in materials, equipment and personnel. This ultimately improves your construction schedule, thus reducing your construction costs. Some of the advantages include: 

• Dry System, no water for concrete or for augering
• Reduced construction time
• Less clean up, no excavation or spoil removal
• Environmentally friendly, soil stays in the ground
  
• Installation unaffected by weather
• Holding capacity verified during installation
• No harmful vibrations during installation
• Can work in limited/restricted access areas
• Equipment can operate in rough uneven terrain
• Construction unaffected by high water table
• Removable and reusable
• Installs with common construction equipment
• Interfaces with structural steel members
• Interfaces with concrete slabs or sleepers
• Lightweight, easy to handle and transport
• Minimum lay down area required
• Small, mobile installation equipment
• Reduced number of workers per crew
• Reduced support equipment requirement
• Fast delivery to the jobsite

 Helical Piling: Advanced Technology and Flexible Solutions for  Deep Foundation Projects

Advances in Helical Piling Technology

Recent advances in technology and equipment have opened up new application opportunities for helical piling installers and for their clients. Larger hydraulic equipment enables the owners and contractors to specify helical piling on projects where higher foundation loads are required. Helical piling now routinely have shaft sizes of 8-inch, 12-inch and larger. When coupled with larger helix diameters,  increased piling   load capabilties are common. Equipment  output torque capacities have also increased which means higher helical piling design loads are achieveable. It's not uncommon to have design loads of 50 to 100 tons and more for a single helical piling. Helical piling tests routinely reach loads of 300 tons. Equipment now has output torques of 300,000 ft. lbs. or greater. These capabilities give the engineer, designer and contractor more options for their deep foundations for any project.
