Anchors

An essential system for the stability of your structures

For stabilizing dams

Wanapum Dam | Beverly, WA

When workers noticed a slight misalignment on the dam during a routine investigation, we were contracted to install post-tension anchors and solid bar anchors as part of the repair solution for Monolith 4.

MDOT Jackson and Mechanic Bridge Repair | Jackson, MI

The Michigan Department of Transportation replaced two century-old bridges located on a segment of railroad within the high-speed rail corridor between Chicago and Detroit. We were contracted to install micropiles to support the new bridge abutments, and permanent soil anchors as part of new earth retention walls used to raise the existing railroad grade, increasing the roadway clearance for vehicles.

North Hill Multifamily Development | Alexandria, VA

A new development in Virginia required two retaining walls to grade the site for the construction of a multi-family neighborhood and townhome complex. We built two massive, anchored retaining walls to support both areas of the development.

What are anchors?

Anchors are tension elements typically post-tensioned to transfer loads from a structure to competent soil or rock stratum.

How do they work?

Anchors are used to provide preloading of structural systems by applying a lock-in tension load in the anchor tendon, which is then bonded to competent rock or soil using rock or cement-based grout. The pre-applied load in the tendon helps to limit structure movement.

Why do you need anchors?

Anchors are used to support walls against lateral earth and water pressures in earth retaining structures, to secure landslides, tunnels, shafts and deep excavations. They are also used to provide resistance for tensile uplifts on basements due to elevated groundwater and overturning or sliding forces in dam stability projects.
