Retaining Walls and Tie Backs

Helical Piles can be installed temporarily for braced excavations or for permanent retaining walls.

Helical Plates

All plates are fabricated with Grade 50 steel while most everyone else uses A-36 grade for the helix plate material. Plate sizes vary from 6″ to 16″ in diameter and have a thickness of 3/8″ or 1/2″ depending on job requirements. The # and sizes of helical plates may be varied to match soil conditions […]

Couplings

Inertia Welded to the shaft ends to allow attachment of extensions for deeper penetration into ground when needed. On both the box end and pin end of every extension we use 4140 & 4125 hardened alloy that we inertia weld to the tube body. We then quench and temper the connection, normalize and then heat […]

Green Structures

Using helical piles with ‘Green” projects will significantly reduce the footprint left on the site.

Connectors / Brackets

The top of the anchor connects to the foundation or structure with different types of connectors depending on the application. This allows the loads from the foundation to be transferred to the helical anchors and then to the soil at a deeper level. Ultimately this will give you more bearing surface for load and support. […]

Wireless Torque Indicator

The wireless torque indicator allows real time torque to be viewed and recorded during the installation process of every anchor – you don’t necessarily know with 100% certainty the load capacity of other technologies. Allows for real-time verification of capacity that can be acted upon immediately. The live time torque that is saved, can be […]

Pipelines

Through wetlands and unstable soil, helical piles can support pipelines to prevent buoyancy or compressive issues using a “saddle” system.

Cost

Time is money! Helical Piles take much less time to install than other deep foundation technologies. They can be installed in most weather conditions and through all four seasons of the year. This saves money and cost from delays that weather conditions can cause. They can be loaded immediately after installation. There is no cure time […]

Speed

Helical Piles are can be installed much faster that Caisson and other deep foundation technologies. Fast installation saves time and money. No curing time No weather delays Easy to work with More flexible and easy to correct or change At a rate of 15 RPM’s and an advancement of 3″ per revolution, a typical 30′ section […]
