Profile: Geo Craft Builders specializes in providing ground anchor systems, ground stabilization, and foundation underpinning services. Rock anchors are often used for new communication tower construction or tower retrofits situated on a remote mountain top. The tower foundations are founded in bedrock that is at or very near the surface. The tower leg foundations rely on rock anchors for increased stability. Rock anchors can be drilled and installed with mobile equipment. Tiedown anchors are often used for subsurface structures build at or below the groundwater table to resist buoyant uplift forces present when groundwater levels are higher.
