Let’s Review the Different Types of Ground Anchors
When you need to hold soil loads in place during and after a construction project, you can take advantage of ground anchoring systems, also called earth or soil anchoring systems. You can use one of several types of ground anchors to hold the earth in place so you can complete your project. Let’s look at the different ground anchor types Intech Anchoring offers and installs. Then you can determine which type meets your project’s earth anchoring requirements.
What Types of Ground Anchors Do We Offer?
We offer three main types of anchors, and each type has its own applications, installation methods, and advantages. These anchor types include:
- Soil nails: Soil nailing systems are gravity composite soil structures located in vertical cuts or excavated slopes. In these systems, closely spaced reinforcement elements, such as ground screws, hold the composite soil structures in place for long-term earth retention. The soil nail install process occurs in two steps: first, a contractor installs soil nails at the top of the slope’s excavation and works downward; second, they apply a temporary or permanent facing to retain the soil in that spot. We offer two types of soil nails: screw anchor nails and grouted nails. Soil nails work best for the following applications: retaining walls, roadway widening beneath bridges, landslide remediation, and slope stabilization.
- Ground Screws: Our ground screws are AB Chance helical anchors, and they’re often called earth screws or soil screws. Each anchor has a helical end-bearing plate welded to a central steel shaft. Ground screws appear in earth retention systems that laterally stabilize soil for temporary or permanent walls. When a contractor installs the ground screws’ helical plates, they give the plates a 3-inch pitch and space them far enough apart that each plate functions as an independent load-bearing element. Ground screws work well for the same applications as soil nails, plus retaining wall repair and reconstruction.
- Tieback Anchors: Tieback anchors are horizontal elements that reinforce retaining walls, basement foundations, or earth shoring walls. Contractors drill or screw tieback anchors into place and install these earth anchors in segments. Then they secure the tieback anchors to the wall or foundation. Tieback anchors work well for projects with limited access. They have the following applications: retaining walls, seawalls, shoring, sheet piling, and timber lagging walls.
We provide these earth anchors to contractors who use them in commercial and residential construction projects. We offer products that can handle your project’s anchor loads, no matter what type of anchor you need.
What Types of Soil Do Our Earth Anchors Work With?
Different anchors work with different types of soil. For example, soil nailing works best with soft soil that’s prone to landslides. Soil nails include steel bars that keep soft soil from sliding out of place. Tieback anchors, on the other hand, work best with soil located in limited-access areas. Soil type and density determine what type of anchor you should install in your wall or foundation. We provide the anchors that best fit the soil types and densities involved in your project.
What Brands of Anchors Do We Provide?
We provide CHANCE helical anchors and Magnacore self-drilling anchors and tieback anchors. AB Chance helical anchors have been used in the electric transmission industry since the 1960s, but contractors now use them often in civil construction. Why? Because they are versatile and cost effective, and they provide solid uplift solutions.
Magnacore’s self-drilling anchors have become popular with contractors because they don’t require extra grouting before installation, and they leave little mess behind after installation. How is that possible? The self-drilling anchors are hollow bar micropiles. The hollow bar injects a high-pressure cement grout mixture into the ground. This mixture forms the micropile and serves as the drill string. The micropile exits the bar and permeates the loose soils in the foundation or behind the retaining wall to form a solid reinforcement column.
The anchors we provide take on whatever load transfers your project requires. Each brand has its advantages, and we can send you whichever one you require for your current project.
