New Mexico's landslide risk concentrates in the Rio Grande rift zone's volcanic and sedimentary formations, where I-25 and I-40 corridors cross slopes destabilized by a combination of seismic activity along rift-related faults and monsoon-triggered flash saturation — a dual mechanism distinct from the single-cause failures NMDOT's maintenance program more commonly addresses.
GSI treats this as one of several Steep Slope Stability Issues issues the state's infrastructure owners regularly face.
GSI's soil nail systems for New Mexico's rift-zone slopes account for both static loading and the seismic loading this active tectonic setting periodically generates, incorporating USGS regional seismic data into the design. This draws directly on GSI's soil nailing work.
New Mexico's monsoon-driven flash infiltration into volcanic ash and sedimentary interbeds requires horizontal drains sized for rapid, high-intensity events rather than steady seasonal seepage. GSI's Soil Nail Launcher™ capability supports this step.
Volcanic ash interbeds common in New Mexico's rift-zone stratigraphy collapse around conventional boreholes on contact — the Soil Nail Launcher™ installs before the ash layer has time to react. This is one application of GSI's broader horizontal drains expertise.
GSI often considers landslide emergency response alongside this work when scoping New Mexico projects.
Engineered for New Mexico's conditions. GSI integrates seismic loading from the active Rio Grande rift into New Mexico slope designs — a consideration most standard slope repair specifications in non-seismic states don't include. GSI's general contractors and asset owners experience backs this approach.
Design/build delivery. Design and build responsibility sit with one team — removing the handoff delays between design and field work.
NMDOT specification compliance. Engineering documentation and installation practices meet DOT standards from first submittal.
