Cased micropile installation is only half the scope. The load test program, structural connection design, and PE-stamped submittal your owner's structural engineer requires are the other half — and most specialty foundation subs don't bring that engineering capability. When the submittal fails owner review, your foundation schedule falls behind your steel erection by weeks.
GeoStabilization International provides cased micropile installation as a design-assist subcontract. Our in-house engineers prepare the pile design and load test program, manage the submittal cycle, and carry the PE stamp your owner's engineer accepts. Installation begins only after the design is approved.
As a cased micropile subcontractor, GeoStabilization International integrates pile design, drill-and-grout installation, and structural load testing into a single managed scope.
Cased micropiles develop bearing and tension capacity through steel casing and grout column to depths exceeding 100 feet in complex soil profiles — cobbles, fill, karst, and fractured rock. GSI drills to competent bearing regardless of intermediate soil variability.
Foundation bearing micropile systems for new bridge abutments and retaining wall footings are installed by GSI crews during the substructure phase — coordinated directly with your concrete formwork schedule.
Pre- and post-installation settlement monitoring by our field engineers provides the structural documentation your project engineer needs to approve pile acceptance and release the foundation design for superstructure loading.
The most common cased micropile schedule problem is the engineering-installation gap: the owner's structural engineer approves a pile design, the prime awards a separate foundation sub, and the field sub discovers the design doesn't match actual boring conditions. RFIs, redesign, and revised submittals consume two to four weeks. GeoStabilization International closes that gap by employing engineers and running the drill on the same project.
When a boring condition differs from the design, our geotechnical PEs revise the design and our crew continues drilling — same day. That integrated decision capability means the first pile and the last pile both match the approved design.
