Self-Drilling Anchors

Magnacore anchors are self-drilling, meaning that there is no predrilling required and grouting is completed during installation.


Magnacore Micropiles can be used in a variety of applications. Particularly useful when projects are launched in areas with limited access or weak soil, Micropiles have become a preferred method of deep foundation stabilization for their reliability, versatility, and efficiency.

Tieback Anchors

A tieback is a horizontal rod used to reinforce retaining walls for stability. With one end of the tieback secured to the wall, the other end is anchored into the earth with sufficient resistance. By utilizing Magnacore SDA’s for Tiebacks, you can save time and money with quick, efficient, all-in-one installation.

Soil Retention Anchors

Earth retention systems are constructed to provide support where deep excavations are made or slope stability is a concern. The design of these systems must consider movement control, stability during construction and wall drainage. Magnacore can be utilized for jobs specified for slope stabilization, soldier pile & lagging, and tieback anchors.
