What CHANCE Products Does Intech Offer?

Intech offers a variety of CHANCE products, including:

CHANCE Helical Anchors

While CHANCE helical anchors have been used as the primary anchor solution for the electric transmission industry since the 1960s, they’re seeing increased popularity in civil construction applications because of their versatility and cost effectiveness. Helical anchors are commonly used as an earth anchoring solution because they offer quick installation and immediate load testing. Other benefits of helical anchors include:

• High production capabilities
• Minimal soil displacement during installation
• No spoil removal required
• Easy installation in limited access areas

Helical anchors resist tensile loading and are installed by segmenting the anchor with breaking plates and a central steel square shaft. This shaft strengthens the ground by transferring the load from the soil to the bearing plates. The system capacity reaches up to 55,000 pounds per anchor, and there’s minimal soil disturbance because the anchors are screwed into the ground.

CHANCE Helical Piles

CHANCE helical piles are used worldwide to secure residential and commercial building foundations. They’re an economical solution to underpinning systems by transferring load weight to bearing places in stable soil. Helical piles are an ideal solution for stabilizing foundations and offer the following advantages:

• It doesn’t require heavy equipment
• Quick installation
• Limited excavation
• Low-access installation

Helical piles are installed by excavating a small hole at each pile location and using a rotary machine to drill the anchors into the soil. Extensions are added to the anchor until the appropriate depth and torque are achieved. The installer then attaches a bracket to the pile and transfers the load to the anchor, stabilizing the foundation beneath a building.

CHANCE Helical Piers

CHANCE helical piers secure residential and commercial buildings, tower foundations, and other deep foundation structures. Some of the advantages of using helical piers include:

• Turnkey installation
• Environmentally friendly
• Doesn’t require concrete
• They’re installed in any weather

Helical piers feature a simple mechanical design that balances the capacities of the major components, including:

Helix

Steel bearing plates are formed into a helical shape that minimizes soil disturbance during installation. The helical bearing plates transfer the load to the soil bearing stratum located deep below the ground surface.

Central Shaft

The central shaft transmits torque to the helical plates during installation. The shaft must have the structural capacity and resistance to withstand the applied stresses from the structure.

Termination

The termination transfers the load down the shaft through the plates and into the bearing soil by connecting the structure to the pile’s top. The termination may be a manufacturing bracket or a separate attachment manufactured on-site as designed by an engineer.

CHANCE Helical Pulldown Micropiles

CHANCE helical pulldown micropiles are a system for constructing grout columns around a steel shaft. They combine the end bearing of a helical plate and skin friction along the grout column to provide a higher bearing capacity. Micropiles are ideal for bridges, weak soil sites, and new construction and offer the following benefits:

• Quick installation
• No pre-drilling
• Predictable results
• Requires a limited workforce

Micropiles are installed by placing helical piles into the soil and applying torque to the shaft. Drilling extensions create a cylindrical void around the shaft into the pile, and grout fills the void surrounding the shaft.
