When “Good Enough” Becomes a Bigger Problem
We’ve seen it all — gravel-filled holes that turn into swamps, plastic pipes buried flat, and downspouts draining into the middle of a lawn. Most homeowners mean well, but drainage is more technical than it seems. Here’s a breakdown of common DIY drainage solutions we’ve been called to fix — and what we install instead to solve the problem permanently.
1. The “Rock Pit” Trick
1. The “Rock Pit” Trick
DIY idea: Dig a hole, fill it with gravel, and call it a drywell.
Why it fails:
Water has no exit, so it just pools
Clay soil traps water instead of draining it
Turns into a muddy, mosquito-breeding pit over time
What works instead:
Properly sized drywell with an overflow outlet
Connected to a French drain or gutter system
Installed with filter fabric and designed for runoff volume
2. Flat Drain Pipe with No Slope
2. Flat Drain Pipe with No Slope
DIY idea: Bury perforated or solid pipe flat to “drain” water.
Why it fails:
No slope means no water flow
Water sits and backs up inside the pipe
Often no proper outlet, causing failure
What works instead:
Minimum 1% slope (1-inch drop every 10 feet)
Clear discharge point like daylight, emitter, or drywell
Use solid pipe only downstream of water collection zone
3. Splash Blocks Without Extensions
3. Splash Blocks Without Extensions
DIY idea: Place a splash block under a downspout.
Why it fails:
Only diverts water a few feet away
Water still pools near the foundation
Ineffective during heavy rain or snowmelt
What works instead:
Extend downspouts 10–15 feet with buried solid pipe
Connect to a French drain or dry creek bed
Add erosion control at discharge points
4. Layering Soil Over Wet Areas
4. Layering Soil Over Wet Areas
DIY idea: Add topsoil to cover wet spots.
Why it fails:
Creates a sponge that traps water near the surface
Doesn’t correct poor grading or drainage
Can suffocate turf roots and worsen conditions
What works instead:
Regrade area with proper slope away from structures
Install subsurface drainage solutions as needed
Amend or replace compacted soil with proper base prep
5. French Drains Without Filter Fabric
5. French Drains Without Filter Fabric
DIY idea: Dig trench, add gravel and pipe, then backfill with dirt.
Why it fails:
Soil quickly clogs gravel and pipe
System loses drainage ability within a season
Total failure often happens after first freeze/thaw cycle
What works instead:
Use geotextile (filter) fabric lining trench walls
Backfill with washed gravel, never soil
Wrap pipe with a filter sock
Finish surface with gravel or sealed layer before sod/mulch
Why These Mistakes Are So Common
Why These Mistakes Are So Common
Most DIY guides skip critical steps — like proper slope, reliable discharge points, understanding soil type, and freeze depth considerations. Effective drainage requires more than digging; it demands understanding how water moves (and doesn’t) across your property.
