Expert Foundation Excavation in Bexar County, TX

Foundation excavation in Bexar County requires more than moving dirt. The county's soil shifts between expansive Houston Black clay in the central and southern areas and shallow limestone bedrock in the north. That variation means every dig must account for what's underneath before a single footing is poured. At TPM Enterprises, we read the site first. We assess grade, drainage slope, and soil behavior before we break ground. Then we excavate to the correct depth and profile for your foundation type, whether that's a slab, footing trench, or pier layout. We remove spoil cleanly, maintain safe trench walls, and leave a level, compacted base ready for your concrete crew. Bexar County's clay soils swell with rain and shrink in dry spells, so proper depth and drainage slope are not optional. If your project is in the unincorporated county and disturbs one acre or more, a Site Development Permit is required before work begins. We work with property owners and builders across Bexar County who need a solo operator they can reach directly. Call TPM Enterprises to schedule a site visit.

Mark and his team did an amazing job. I had a horrible first contractor and should have just gone with TPM in the first place. They came in fixed the base pad for my home the same day. Replaced drainage pipes and vent pipes that the other contractor had broken. TPM always called and kept me updated on what the plan was for the day/week. They got the job done within the week. Installed my water lines, electric pole, electric lines, finished my base pad off, and fixed my piping for my septic system. No problems at all whatsoever with them do not make the mistake of going with someone else make sure you call TPM first and you won’t have to call anyone else or have any problems.
