A french drain is a trench filled with gravel and a perforated pipe that intercepts groundwater or surface runoff and redirects it away from problem areas. When properly designed for your soil type and installed with adequate slope and the right filter fabric, a french drain is one of the most effective long-term solutions for drainage problems.

Arlington sits between Dallas and Fort Worth, one of the largest cities in the Metroplex and home to AT&T Stadium and Globe Life Field, whose explosive growth from the 1960s onward — well before Dallas or Fort Worth's more recent suburban booms — means the city carries a genuinely wide range of housing and drainage-infrastructure eras layered on top of each other, from 1960s-70s postwar construction to much newer development on its remaining undeveloped edges. Tarrant County's Eagle Ford and Woodbine clay formations produce real shrink-swell behavior, and Arlington's status as a dense, largely built-out inner-Metroplex city means less undeveloped land is available to absorb stormwater runoff during North Texas's periodic intense rain events than in newer, more spread-out outer suburbs — a real factor during major sporting and entertainment events that also concentrate a lot of paved surface runoff in a short window. The dense paved footprint around both major stadiums means game-day and event-day runoff volumes here are genuinely unlike anything found in a purely residential Metroplex suburb.

How French Drains Work

Water follows gravity. A french drain intercepts that flow by providing a path of least resistance — the gravel-filled trench allows water to enter from the surrounding soil, where it's collected by the perforated pipe and directed to a discharge point. The key variables are slope (minimum 1% grade for adequate flow), filter fabric selection (prevents soil migration into the gravel), and outlet placement (daylight outlet, dry well, or street). Getting these right is the difference between a drain that lasts decades and one that clogs in a few years.

Common Applications in Tarrant County

The contractors we connect you with install french drains along foundation perimeters to intercept water before it reaches the structure, across yards to interrupt subsurface water flow toward the home, and in low-lying areas where water consistently pools. In Tarrant County's clay soils, proper filter fabric selection is especially important — clay particles are small enough to migrate through coarser fabrics and eventually block the drain.
