SeaTac French Drain Installation Services
Does your yard turn into a swamp from November to May? It’s time to ditch the ineffective drainage solutions. Our team specializes in designing and installing properly sloped pipes, clean drain rock, and geotextile fabrics to effectively manage water flow in SeaTac’s unique clay soil.
What’s the Problem?
Is your SeaTac property facing water issues? Here’s what we frequently encounter:
- Standing water in lawns and side yards that lingers for days.
- Mushy footpaths created by foot traffic, pets, or vehicles.
- Downspouts dumping water onto your foundation, risking leaks in your crawlspace.
- Slopes weeping around walkways and stairs after rain.
- Previous attempts at drainage that were just fabric and gravel—leading to frustration!
What We Install (and Why It Works)
We offer a variety of drainage solutions specifically designed for SeaTac:
- French Drains: These perforated pipes are laid in gravel trenches to intercept groundwater before it causes damage.
- Downspout Conveyance: Solid pipes that carry rainwater away from your foundation to an approved outlet.
- Dry Wells / Dispersion Trenches: Perfect for areas where water cannot daylight; sized for your roof and soil, wrapped in non-woven geotextile to keep out fine particles.
- Channel Drains & Trench Grates: These systems catch water on hardscaped surfaces and integrate seamlessly into your drainage system.
- Cleanouts & Inspection Ports: Strategically placed to facilitate easy maintenance.
We don’t just throw fabric and gravel in a trench and call it a day; that leads to clogs and maintenance headaches!
Our Build Method (No Shortcuts Here!)
- Site Assessment: We analyze your property’s elevation and water flow using laser levels.
- Utility Locate: Safety first—we call 811 to avoid underground utilities.
- Trench Creation: Typical dimensions are 8–12” wide and 18–24” deep, lined with non-woven geotextile.
- Base Layer Installation: We add 3–4” of ¾” clean drain rock before placing the pipe.
- Pipe Installation: Perforated pipes are set with holes facing down at a ~1% fall for effective drainage.
- Rock Envelope: We fill to 2–3” from grade with clean, angular rock, avoiding round river rock that shifts.
- Wrap & Cap: We cover with fabric to keep fines out, then top with soil or decorative rock.
- Outlet Installation: We daylight to the curb or install dry wells as required by local regulations.
- Proofing: We conduct tests to ensure proper flow before backfilling.
Connecting drains to a sanitary sewer is a no-go. We ensure your outlets are compliant and functional.
French Drain vs. “Pipe in a Trench” (Why Yours May Have Failed)
- No Slope = No Flow.
- Fabric Misplacement = Mud Filter.
- Round Rock Rolls; Clean Angular Rock Locks and Drains.
- Perforated Pipe Under Roof Water = Sludge. Keep Downspouts on Solid Pipe.
- No Cleanouts = No Maintenance.
Quick Sizing Math (For Easy Ordering)
- Trench Volume per Linear Foot
- 8” wide × 12” deep = 0.67 cu ft/LF → ~40 LF per cubic yard
- 12” wide × 18” deep = 1.5 cu ft/LF → ~18 LF per cubic yard
- Rock: Order 10–15% extra for settlement.
- Pipe: Add 10–20% for bends and cleanouts.
