Foundation Drainage & French Drains in North Richland Hills, TX

Foundation drainage work, including French drains, can be the least expensive part of a foundation repair, and it helps keep the repair working. Clay soil swells when it gets wet and shrinks when it dries. When water from roofs, patios and neighboring yards collects along one side of a house, the soil there behaves differently from the soil a few feet away, and the slab moves unevenly. Moving that water away, and keeping the soil around the house at a more even moisture level, is the goal.

Start with the roof

A roof sheds a large amount of water in a heavy rain, and gutters gather it into a few downspouts. A downspout that empties against the foundation puts all that water in one spot. Extensions, splash blocks and underground downspout lines that carry water to the yard or the street are usually the first fix, and the least expensive one.

Grading

Soil around the house should slope away from it. Over the years flower beds get built up, mulch piles against the brick, and patios settle toward the house. Regrading restores the slope so surface water runs away. Swales, wide shallow channels in the yard, can carry water around the house toward the street; the City of North Richland Hills suggests them for runoff coming from a neighbor's lot.

French drains

A French drain is a trench with gravel and a perforated pipe that collects water from saturated ground and carries it to a lower outlet. It suits areas where water soaks in and stays, such as a low side yard or along a slope above the house. Angi notes that French drains are harder to install in clay soil. Surface drains have limits too: the City of North Richland Hills does not generally recommend area drains for surface flow, noting they typically lack the capacity for runoff heavy enough to threaten a home and must be cleaned of leaves and debris often.

Where the water goes

The outlet matters as much as the drain. North Richland Hills' drainage guidance says it is against state water laws to divert or concentrate runoff onto a neighbor, and that property owners are responsible for drainage on their own lots. We plan outlets to the street, a swale or another outlet the city allows, and we point out when a lot-wide problem is better handled by a civil engineer with drainage expertise.

Sprinklers and buried lines

Drainage trenches often cross sprinkler lines. Moving or repairing an irrigation system is licensed irrigation work in Texas, so the owner hires a licensed irrigator for any sprinkler changes. Before we dig, buried utility lines are located and marked.

Steady moisture

Soil that swings between soaked and bone-dry is what moves foundations. Good drainage handles the wet side. In long dry spells, some owners water evenly around the foundation with a soaker hose to slow the drying; follow your city's current watering rules if you do.
