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.
Rather than building a wall to hold a slope or cut face back, soil nailing turns the ground itself into the retaining structure. Crews install a grid of near-horizontal, grouted steel bars into the face from the top down as excavation proceeds, then apply a shotcrete skin over the reinforced soil.
GSI installs soil nails across Dallas 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 matters along the Trinity River Corridor, where saturated floodplain soil can collapse a conventional open borehole before a drilled nail is even placed. GSI's Dallas 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 saturated, actively moving ground well since it doesn't require a stable open borehole.
A conventional drilled nail relies on an open borehole that can collapse in wet, loose floodplain soil before the nail is placed. A launched SuperNail™ is fired in a single shot and compacts the surrounding soil instead.
We evaluate soil strength, saturation, and existing movement before finalizing nail length and spacing, since floodplain and upland clay sites behave very differently.
The launcher unit is mounted on a compact excavator base weighing about two tons, letting crews work in tight or sensitive floodplain-adjacent areas.
Yes. Because launched SuperNails™ don't depend on an open borehole, they install in collapsing or saturated ground where conventional drilled soil nailing struggles.
An unreinforced slope anywhere in Dallas County can keep moving until it threatens the structure or roadway above it. Call (855) 599-5217 to get a soil nailing assessment from a licensed engineer.
