Common Water Issues
Drainage Problems We Solve
Western Washington rain is relentless, and the clay-heavy soils across Olympia, Lacey, Tumwater, Yelm, and greater Thurston County don’t always let it drain away. If water is collecting where it shouldn’t, you’re not alone — and it’s a problem we fix every season with lasting, beautifully finished solutions.
01
Standing Water & Puddling
Pools of water that linger for days after a storm, drowning plantings and turning patios and walkways into hazards.
02
Foundation & Basement Leaks
Damp crawl spaces, musty basements, and water seeping along the foundation — early warnings of costly structural damage.
03
Soggy, Saturated Lawns
Spongy turf, moss, and bare patches that never dry out, leaving your yard unusable for much of the year.
04
Overflowing Gutters & Downspouts
Downspouts dumping roof runoff right beside the house, causing erosion, splash-back, and pooling at the foundation.
05
Erosion & Washed-Out Beds
Mulch, soil, and gravel carried away by runoff, exposing roots and undermining hardscapes and retaining walls.
06
Poor Grading & Negative Slope
Yards that tilt toward your home instead of away from it, channeling every rainfall straight to where it does the most harm.
Recognize any of these? Our team diagnoses the true source of the water and engineers a drainage solution built for Pacific Northwest weather — protecting your home, your landscape, and your investment.
DRAINAGE SYSTEMS
French Drains, Catch Basins & Downspouts
Western Washington rain doesn’t take a day off, and neither should your drainage. We design and install complete collection-and-conveyance systems that capture water at the surface, move it underground, and release it safely away from your home — engineered for the saturated clay soils and long wet seasons of Olympia, Lacey, Tumwater, Yelm, and greater Thurston County.
01
French Drains
A perforated pipe set in a gravel-filled trench and wrapped in filter fabric intercepts groundwater and soggy-lawn runoff before it reaches your foundation, crawlspace, or patio.
- Clean washed drain rock and non-woven geotextile
- Proper slope to a daylight outlet or dry well
- Ideal for perimeter, yard, and hillside seepage
02
Catch Basins
Where water pools — low lawn spots, driveways, patios, and walkways — a catch basin collects surface runoff through a grate and sends it into a solid pipe network before puddles turn into problems.
- Sediment sump to trap debris and protect pipes
- Low-profile grates that blend into hardscape and lawn
- Easy-access design for simple seasonal cleanout
03
Downspout Drainage
A single roof can shed thousands of gallons in one Pacific Northwest storm. We tie downspouts into dedicated underground lines so roof water never dumps beside your foundation again.
- Smooth-wall solid pipe that resists clogging
- Cleanouts for long-term maintenance access
- Discharge to pop-up emitters, dry wells, or approved outlets
Built for Western Washington’s Climate
With 50+ inches of annual rainfall and slow-draining glacial till across much of Thurston County, we size every pipe, basin, and outlet for peak winter flow — so your system works together as one integrated solution, season after season.
GRADING & WATER MANAGEMENT
Shape the Land. Control the Water. Protect Your Investment.
In the Pacific Northwest, the ground beneath your home matters as much as anything built on it. Months of steady rain across Olympia, Lacey, Tumwater, Yelm, and greater Thurston County will find every low spot, flat lawn, and backward-sloping bed. Professional grading puts gravity to work for you, guiding water away from your foundation, patios, and plantings before it can cause damage.
“Water always wins unless the land is designed to guide it.”
Why Grading Comes First
Drains and catch basins work best when the surrounding land is shaped correctly. Proper slope keeps surface water moving in the right direction, reduces the load on your drainage system, and helps prevent soggy lawns, settling pavers, and moisture against your home. It is the foundation of every lasting outdoor living space we build.
01
Precision Re-Grading
We correct negative slopes and low spots so the ground falls away from your foundation, directing runoff toward safe outlets instead of toward your home.
02
Swales & Dry Creek Beds
Gently contoured channels and natural river-rock creek beds carry heavy rainfall across your property while adding texture and beauty to the landscape.
03
Surface Water Redirection
We study how water moves across your yard and from neighboring properties, then design a plan that captures, slows, and safely releases it.
04
Hardscape & Foundation Protection
Properly prepared sub-grades and planned pitch keep patios, walkways, and retaining walls stable, helping prevent heaving, erosion, and costly repairs.
Not sure where the water on your property is going? We will walk your site, identify problem areas, and recommend a grading plan built for Thurston County soils and rainfall.

DRAINAGE FAQ
Frequently Asked Questions
Straight answers for homeowners in Olympia, Lacey, Tumwater, Yelm, and across Thurston County. These are the questions we hear most about upkeep, our local soil, and how long a drainage system lasts in the South Sound's wet climate.
How does Thurston County's soil affect drainage?
Much of the South Sound sits on compacted glacial till and clay-heavy soil that absorbs water slowly, while low areas near Lacey and Tumwater often have a seasonally high water table. We test how your site drains, then size pipe, gravel, and outlets for those conditions so water leaves your property instead of pooling against it.
How much maintenance does a drainage system need?
Very little. Clear leaves and debris from catch basin grates and gutters each fall, and check that downspout connections and outlets are free-flowing before the heavy rains arrive. We build in cleanouts so the lines can be flushed easily if they ever need it.
How long will my French drain or catch basin system last?
A properly installed system with filter fabric, clean drain rock, and quality pipe typically performs for decades. The difference is in the details: correct slope, wrapped trenches that keep silt out, and a sound discharge point. We don't cut corners on any of them.
When is the best time to install drainage?
Late spring through early fall is ideal, when soil is workable and we can finish before the wet season. If you already have standing water or a soggy crawlspace, call us anyway. We can plan and schedule work to fix urgent problems year-round.
Will installation damage my lawn or landscaping?
Some excavation is unavoidable, but we plan trench routes to protect mature plantings and hardscape, keep a clean job site, and restore disturbed areas when we're done. Most homeowners are surprised how quickly the yard looks finished again.
Do you serve my area, and is the estimate really free?
Yes. We work throughout Olympia, Lacey, Tumwater, Yelm, and greater Thurston County. Every project starts with a free, no-obligation on-site assessment and a clear written estimate, so you know exactly what we'll do and why.
