Company Background
About Groundworks Foundation Repair San Antonio
Groundworks Foundation Repair San Antonio lists a run of recognitions on its own site, among them a Qualified Remodeler Top 500 placement for 2024, an Inc. 5000 badge, USA Today Top Workplaces for 2025, BBB 2025 Awards for Excellence and an Angi Super Service Award for 2025. Customers give it 4.8 from 943 Google reviews, read October 21, 2026.
The branch works from 18630 Goll Street, on the northeast edge of the San Antonio metro, and is part of the national Groundworks group. Its own site lists service in San Antonio, Schertz, Cibolo, Converse, New Braunfels, Seguin, Boerne and Kerrville, and as far out as Austin and Victoria. Anthony Martin is the general manager on the team page.
Be clear about what this company is. Foundation repair is the core trade, using helical piers, push piers, wall anchors and concrete lifting. The water control side is narrower than a dedicated waterproofing shop: an interior drain system, sump pumps, crawl space encapsulation with dehumidifiers and crawl space supports. The site does not mention French drains or exterior grading. In a clay and limestone market, pairing the two under one roof is why it belongs here.
Reviewers talk about crews and sales staff by name. One couple praised Tyler, Jay and John across a three day job. Another thanked Carson, Jeremiah, Chris and Roberto. A third credited Isaac and Nathan on site and Rich on the sales side, and a fourth thanked Alex, Junior and Darrel. The five reviews we read were all five stars, so check recent low ratings yourself before booking.
Inspections are free, and the warranty is described as transferable to new owners, though no term in years is published. Financing runs through GreenSky, subject to credit approval. Texas has no state waterproofing licence and the company's licensing page lists no Texas number, so ask for proof of insurance and confirm any plumbing work, such as a sump pump discharge, is done by a TSBPE licensed plumber. Check with the City of San Antonio on permit requirements.
It suits homeowners who want foundation and moisture problems handled by a large, staffed firm. It suits less well anyone who wants a small owner run shop or an exterior French drain. Before booking, ask for the warranty terms in writing, which crew lead will run the job, and who is pulling any permit.
