A typical job runs 1 to 2 weeks once drilling begins; sites with more variable geology may need adjusted pile depths that extend the timeline slightly.
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 to depths of 50 feet or more. That depth lets the pile bypass an unreliable near-surface layer and bear on whichever stratum actually offers stable support.
In Bexar County, that flexibility matters because the geology beneath a given lot can be limestone, marl, or clay depending on exactly where the site falls near the county's military installations and I-35 corridor. GSI's Bexar County micropile work typically centers on:

Cost depends on pile depth, diameter, and how many piles the load requires, which our engineers determine after confirming which geologic layer the site actually sits on.
Yes. Every design is stamped by a licensed Professional Engineer and meets IBC and Texas Building Code requirements.
GSI offers 24/7 emergency response and can typically mobilize a crew within hours of a call.
Helical piers work well in soft soil but can lose reliable capacity in limestone or marl layers common in the area. Micropiles are drilled rather than screwed in, allowing the bearing layer to be verified before load is applied.
We drill test borings at the specific pile locations to confirm the actual geologic layer present, rather than assuming a single soil profile applies across the corridor.
Micropile drilling generates minimal vibration and a small footprint, which limits disruption to nearby infrastructure and operations.
Yes. Pile depth and design can be adjusted pile-by-pile if test borings confirm the bearing layer varies across the site.
Every season the ground beneath an under-supported Bexar County foundation keeps shifting, and repair costs climb with it. Call (855) 599-5217 to get a micropile assessment from a licensed engineer.
