Groundwater & Basement Water Intrusion in Leander, 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
Why is this area singled out for flash flooding?
The escarpment here lifts moist Gulf air abruptly, which produces some of the highest rainfall rates recorded anywhere in the country. Underneath it is thin soil over rock with almost no storage, and creeks that fall steeply into narrow valleys. The combination turns an intense storm into a wall of water within minutes rather than hours.
The creek is dry almost all the time.
That is the normal state and it is exactly what makes these channels dangerous. A dry bed gives no visual cue about what it carries in an event, and on this ground it can go from nothing to a substantial flow in under half an hour. Judging one of these creeks by how it looks on an ordinary day is the standard mistake here.
Everything here was built in the last fifteen years.
Which means the drainage was designed to modern standards, and also that the whole catchment converted from ranch land to roof and pavement inside a single decade. Downstream channels shaped by the old runoff regime now receive a much sharper peak. Modern design on each site does not by itself resolve what the aggregate change did.
