A tieback anchor not proof-tested to design load is an unapproved element — and a tieback that fails its load test after you've poured the wall cap is a project crisis. The subcontractor who drills and grouted tiebacks without carrying geotechnical engineering support for the test protocol puts your acceptance timeline and structural warranty at risk.
GeoStabilization International provides tieback anchor installation as a geotechnically managed specialty subcontract. Our in-house engineers design the anchor length, inclination, and pre-stress schedule, and our crews perform proof and performance load tests to PTI standards. Your tieback submittal is stamped by the same engineers who designed the anchor system.
GeoStabilization International provides tieback anchor subcontract services on soldier pile walls, sheet pile shoring, retaining wall rehabilitation, and slope stabilization projects — design, installation, and testing under one subcontract.
Permanent post-grouted tieback anchors provide long-term lateral support to retaining walls, building foundations, and slope reinforcement systems. GSI drills to the anchor zone, installs post-grouted tendons, and proof-tests to PTI standards before stressing.
Temporary tieback anchors for deep excavation shoring are installed by GSI crews on a schedule aligned with your excavation lifts — drilling, grouting, and stressing at each lift level without delaying internal excavation operations.
PTI-standard proof and performance load tests are documented by our field engineers and submitted to your owner's structural engineer for approval. Load-extension records and acceptance documentation prepared in owner-specified format.
Tieback subcontracts that split the design from the installation create a coordination gap at the most critical phase: when the load test reveals the anchor didn't develop design capacity. Who revises the anchor design? Who remobilizes for re-testing? Who carries the delay cost?
GeoStabilization International eliminates that gap by employing geotechnical engineers and installation crews under one subcontract. When a tieback anchor doesn't pass its proof test, our field engineer identifies the cause and our crew drills the replacement anchor while the engineer revises the design — one call, one resolution, no schedule hold.
