How a French Drain Works
Proven subsurface water management
A French drain is a gravel-filled trench with a perforated pipe that captures and redirects water away from structures and saturated zones. The system relies on gravity, using a consistent slope to move water toward a safe discharge point such as a daylight outlet or a dry well. Wrapped in non-woven geotextile, the assembly filters sediment, relieves hydrostatic pressure around foundations and retaining walls, and intercepts both surface runoff and lateral groundwater.
When properly designed, a French drain prevents basement seepage, stabilizes walkways and patios, reduces lawn puddling, and mitigates erosion. It can be integrated with downspouts, curtain drains, and swales to create a comprehensive drainage plan, and cleanout ports allow periodic maintenance to extend service life.
Recognize the need before damage spreads
Persistent puddles lasting more than 24–48 hours, spongy turf, algae or moss growth, heaved pavers, and musty odors indoors are common red flags. You may also notice efflorescence on foundation walls, standing water near fence lines, or mosquito activity around low spots after rain.
Risk factors include dense clay soils, compacted subgrades from construction, negative grading toward structures, lots at the base of slopes, and high water tables. If downspouts or sump pumps discharge near the home, a French drain provides a controlled pathway that protects foundations and landscaping.
Precision built for niche landscapes
Every project starts with a detailed assessment: utility locates, elevation mapping with laser levels, soil infiltration checks, and evaluation of discharge options such as daylight, dry wells, or storm tie-ins. Gordon Landscaping specializes in niche landscaping for land owners, tailoring layouts to preserve trees, habitat plantings, driveways, and other site-specific features while minimizing disturbance.
We build to proven specs: trenches typically 8–18 inches wide and 18–36 inches deep, a minimum 1% fall, 4-inch perforated PVC or HDPE pipe, and 3/4-inch washed angular stone. Non-woven geotextile encases the system to resist clogging, cleanouts are placed every 50–100 feet, and catch basins capture surface water. We can integrate downspouts with debris filters, protect outlets with riprap, and add freeze protection where needed.
After installation, we restore grading, topsoil, sod or seed, and any disturbed beds or hardscape edges. You receive an as-built layout and maintenance guidance: flush cleanouts annually, clear basin grates, and inspect outlets after major storms. Expect transparent pricing, clear timelines, and workmanship backed by a robust warranty.

Local Drainage Planning That Works
Design tuned to your property’s conditions
In Leavenworth, varied slopes and seasonal snowmelt can overload soils. We size pipe capacity and set fall to handle intense spring runoff, consider river-influenced water tables, and protect outlets against freeze–thaw cycles common in Leavenworth.
Properties in Leavenworth often combine fast-draining gravels with pockets of dense clay. We test infiltration to determine whether a daylight outlet, dry well, or storm connection is appropriate, and we choose materials and filtration that stand up to the conditions found in Leavenworth.
