Texas's landslide risk spans the Balcones Escarpment's limestone terrain around Austin and San Antonio and the expansive clay slopes of the Blackland Prairie further east, and along I-35's central corridor, TxDOT sees slope failures driven by two very different mechanisms depending on which side of the Escarpment the site falls on — a geologic transition most single-approach repair specifications don't account for.
GSI sees this alongside other Steep Slope Stability Issues work across the state's infrastructure network.
GSI's soil nail designs for Texas differ by geologic province: Balcones Escarpment limestone slopes get reinforcement anchored into competent limestone, while Blackland Prairie clay slopes get reinforcement designed around expansive clay's swell-shrink behavior. GSI's soil nailing experience informs this approach.
Karst-influenced groundwater near the Balcones Escarpment and expansive-clay-perched groundwater in the Blackland Prairie require distinctly different horizontal drain strategies, which GSI designs independently for each Texas geologic setting. This draws directly on GSI's Soil Nail Launcher™ work.
Whether the challenge is a karst-affected limestone borehole or a swelling clay borehole, the Soil Nail Launcher™ installs without depending on either material's cooperation during conventional drilling. GSI's horizontal drains capability supports this step.
Where relevant, landslide emergency response is factored into the Texas project plan from day one.
Engineered for Texas's conditions. GSI designs Texas slope repairs around the state's genuine geologic split — Balcones Escarpment limestone versus Blackland Prairie expansive clay — not a single approach applied statewide. This is reinforced by GSI's work in general contractors and asset owners.
Design/build delivery. A single accountable team delivers design and build — removing the handoff delays between design and field work.
TxDOT specification compliance. Project records and construction methods conform to DOT requirements from first submittal.
