A typical job runs 1 to 2 weeks once drilling begins; floodplain sites needing deeper piles to reach firm bearing can take longer.
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 common, since the goal is reaching a bearing layer well below the surface rather than spreading load across a shallow footing.
In Dallas County, that deeper bearing point often means passing through expansive clay to reach the Austin Chalk limestone in the western part of the county, or through soft floodplain soil along the Trinity River Corridor to reach firmer ground below. GSI's Dallas County micropile work typically centers on:
A typical job runs 1 to 2 weeks once drilling begins; floodplain sites needing deeper piles to reach firm bearing can take longer.
Cost depends on pile depth, diameter, and how many piles the load requires, which varies based on whether the site is in floodplain soil or upland clay.
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 in soft soil but have lower load capacity, which matters near the floodplain where piles may need to extend well past soft surface soils. Micropiles carry heavier loads to greater depths.
We drill test borings to confirm the actual depth to firm ground, whether that's rock in the western county or a firmer stratum below floodplain soil.
Micropile drilling generates minimal vibration and a small volume of spoils compared to driven piling, making it a practical option in sensitive floodplain-adjacent areas.
Yes. Because micropiles bear on deeper, firmer strata and use grout rather than large excavations, they're a common solution where floodplain soil would undermine a shallow foundation.
Every season the ground beneath an under-supported foundation in Dallas County keeps shifting, and repair costs climb with it. Call (855) 599-5217 to get a micropile assessment from a licensed engineer.
