Launched nails install at up to roughly 250 twenty-foot nails per day, so most walls complete in days rather than the weeks a conventional drilled system requires.
Soil nailing turns the ground itself into the retaining structure instead of building a separate wall to hold a slope or cut face back. Crews install a grid of near-horizontal grouted steel bars into the face from the top down as excavation proceeds, then finish the surface with shotcrete.
GSI installs soil nails across Bexar County using our patented Soil Nail Launcher™, which fires a launched nail into the slope at up to 250 miles per hour instead of drilling a conventional borehole. That advantage matters where marl or fractured limestone layers can compromise a conventional open borehole, since the launched nail doesn't depend on that hole staying stable. GSI's Bexar County soil nail projects typically involve:
Launched nails install at up to roughly 250 twenty-foot nails per day, so most walls complete in days rather than the weeks a conventional drilled system requires.
A soil nail wall typically costs 25 to 50 percent less than an equivalent-height soldier pile wall and becomes a permanent structure. We provide a fixed-cost proposal after reviewing site conditions.
Yes. Every design is stamped by a licensed Professional Engineer and meets IBC and Texas Building Code requirements for permanent earth retention.
Yes. GSI offers 24/7 emergency response, and the Soil Nail Launcher handles variable or unstable ground well since it doesn't require a stable open borehole.
A conventional drilled nail relies on the borehole staying open, which fractured rock or soft marl can undermine mid-drill. A launched SuperNail™ is fired in a single shot and doesn't depend on that hole remaining stable.
We evaluate the specific mix of rock and soil at the site before finalizing nail length and spacing, since conditions can vary meaningfully within a single corridor.
The launcher unit is mounted on a compact excavator base, letting crews work efficiently and with a smaller footprint near sensitive infrastructure.
Yes. Because launched SuperNails™ don't depend on an open borehole, they install effectively through fractured or variable rock where conventional drilled soil nailing can struggle.
An unreinforced slope along Bexar County's growth corridors can fail without the warning signs a more uniform site would show. Call (855) 599-5217 to get a soil nailing assessment from a licensed engineer.
