Foundation Drainage in Georgetown, TX

Foundation drainage in Georgetown starts with a basic question: what is your house sitting on? On the east side, homes rest on Blackland clay that swells and shrinks with moisture, and slabs there can move. On the west side, many homes sit on thin soil over limestone, which is more stable, but cut-and-fill lots can have patches of fill and clay that settle unevenly. Drainage does not fix a foundation, and we do not do structural foundation repair. It manages water so the soil stays steadier. A simple habit helps on both sides of town: check gutters and the soil line twice a year. Many foundation moisture issues begin with a clogged gutter, a sunken planting bed, or a downspout that fell off the elbow. Fixing those costs little.

A good drainage plan for a Georgetown house starts at the roof. Gutters and downspouts should carry water well away from the walls. Next comes the grade, with soil sloping away and sitting below the brick line. Then, if water still gathers beside the slab, a shallow French drain or a surface swale can intercept it. Older homes near downtown may have pier-and-beam foundations with crawlspaces, where water pooling under the house is a sign that drainage and ventilation need attention. Crawlspace homes need ventilation and a dry floor. If you see standing water, mold, or soggy insulation under a pier-and-beam house, grading and exterior drains may help, but a licensed pro should assess moisture and structure together. Photograph the area around the house after a heavy rain so you can see where water gathers.

If you see cracks above doors, sticking windows, or sloping floors, bring in a structural engineer or a foundation repair company before you spend money on drainage. They can measure the slab and say whether it has moved. Then drainage becomes part of protecting the house. On rocky lots, a high spot of limestone next to the foundation can also channel water toward the wall, so we study how rain moves across the whole lot, not only along the edge of the house. In dry spells, watch for soil pulling away from the slab. Gaps wider than a pencil can let storm water run straight down to the footing. Fill them with compacted soil and follow your engineer's advice on how much to water.

Be careful with any claim that drainage alone will fix a damaged foundation. It will not. Drainage reduces one of the forces acting on a slab. It cannot undo cracks, uneven floors or stuck doors that have already developed. If you see stair-step cracks in brick, doors that rub their frames, gaps between walls and ceilings, or floors that slope, call a licensed structural engineer or a foundation repair company first. Many homeowners get an independent engineer's report so they have an unbiased view of what the slab needs. Once the structure has been evaluated, drainage becomes the maintenance side of the plan. A repaired foundation that keeps getting soaked on one side can move again. A stable foundation with good drainage is more likely to stay that way.

A word about watering foundations. In dry summers, some Central Texas owners run soaker hoses around the slab to keep the clay from shrinking. Opinions on this differ, and the advice we found is mostly from contractors rather than neutral research. Watering unevenly can cause the same differential movement you are trying to prevent. If you want to try it, ask your engineer or foundation repair company what pattern and schedule fit your slab and soil, and keep hoses away from areas where water also ponds. Finally, before any trench is dug, Texas law requires a call to 811 at least two business days ahead so buried lines are marked. Your HOA or city may also have rules about changing grade or draining toward easements, so ask before work starts.

The San Gabriel River is the defining water feature. Two dams on the river created Lake Georgetown and Granger Lake. Before those dams, periodic large but short floods shaped the river bottoms east of town, which are now wooded with oak and pecan. Smaller creeks and draws feed the river, and many neighborhoods have drainage channels or greenbelts running between lots. Terrain is hilly on the western side, so water moves quickly downslope and can cut channels through beds and gravel, wash out mulch and push soil toward the street. On the flatter east side, runoff spreads out and slows. We study the slope of your lot, and the lots above it, before suggesting any fix. Lake Georgetown sits on the North Fork of the San Gabriel River west of town, and the city's creeks and draws feed the river system below it, so a lot near a draw may carry fast water after a storm.
