A typical job runs 1 to 2 weeks once drilling begins; steep or hard-to-access sites may take somewhat longer to mobilize compact equipment for.
A micropile is a slender, deep foundation element built by drilling a small borehole, typically under a foot across, inserting a steel reinforcing bar or pipe, and filling the hole with structural grout. Depths of 50 feet or more are possible, though in rocky Hill Country terrain the bearing point is often much shallower once solid rock is reached.
In Travis County's unincorporated Hill Country, that means a micropile foundation often anchors directly into limestone close to the surface rather than needing the greater depths a clay-heavy site elsewhere in Central Texas might require. Because micropile rigs are compact, they also fit narrow or steep lots where larger foundation equipment can't set up. GSI's Travis County micropile work typically centers on:
A typical job runs 1 to 2 weeks once drilling begins; steep or hard-to-access sites may take somewhat longer to mobilize compact equipment for.
Cost depends on pile depth, diameter, and how many piles the load requires; shallow bearing on Hill Country rock can sometimes reduce depth requirements compared to clay-heavy sites.
Yes. Every design is stamped by a licensed Professional Engineer and meets IBC and Texas Building Code requirements applicable to unincorporated construction.
GSI offers 24/7 emergency response and can typically mobilize a crew within hours, including to more remote unincorporated properties.
Excavating a conventional footing into shallow, hard limestone can be difficult and disruptive. Micropiles drill directly into the rock with a compact rig and far less excavation.
We confirm rock quality and depth at the specific pile locations rather than assuming uniform bearing conditions across a sloped or varied lot.
Micropile drilling generates minimal spoils and doesn't require large-scale excavation, limiting disturbance on sensitive or heavily wooded Hill Country lots.
Yes. Compact micropile rigs are designed to access narrow, steep, or otherwise constrained sites that larger foundation equipment can't reach.
Erosion and rock movement on a Hill Country property can undermine an under-supported foundation over time. Call (855) 599-5217 to get a micropile assessment from a licensed engineer.
