Groundwater & Basement Water Intrusion in San Antonio, TX
Basement seepage, failed sumps, and hydrostatic pressure against the foundation are extracted and dried, and the path from the ground is identified so the loss does not repeat. Groundwater and basement seepage are extracted and dried only after the path from the soil is identified — a wall, a slab, a drain, or a failed sump. Drying the interior without stopping that path returns the same water to the same floor.
Frequently asked questions
There is a flood tunnel running under the downtown.
There is, bored decades ago to take the river's peak beneath the center of the city and return it downstream. It works and it is worth understanding what it does not do: it defends one corridor. A property three miles away on a different creek is unaffected by it, and the mapping for that creek is what applies there.
Advice that helped across town did nothing at this address.
The city spans two quite different landscapes. On the northern side there is thin soil over limestone, where water travels along seams and arrives from beyond a boundary; to the south it is deeper clay that sheds almost everything at the surface. Those need different remedies. Establishing which of the two a property sits on comes before anything else.
The rules about drainage are stricter on the north side of the city.
That is the recharge zone, where the limestone takes surface water down into the aquifer that supplies the city rather than filtering it through soil first. What reaches the ground there reaches the drinking supply in days. So what may be discharged into the ground is restricted in a way it is not a few miles south, and drainage designs have to account for it.
