Standing water in your yard, water infiltrating your basement, erosion at the property edges, these are drainage problems that get worse with every rain until properly addressed. Middle Tennessee gets 50-55 inches of rain annually with intense storm events. S and S Excavation designs and installs drainage solutions across the region.
Drainage System Types
French drain: perforated pipe in aggregate-filled trench, wrapped in filter fabric. Captures water below grade and routes it to a daylight outlet or dry well. The workhorse of property drainage.
Surface drainage (channel drains, area drains): grated drains capturing surface water from patios, driveways, low spots in yards.
Foundation drainage: perimeter drain at footing level, often combined with sump pump and waterproofing. Stops basement and crawlspace water entry.
Roof drainage: downspout extensions and underground routing of gutter water away from foundation.
Erosion control: swales, riprap, retaining walls to manage water flow across slopes.
Dry wells: below-grade aggregate pits that absorb captured water gradually. Used when daylight outlets aren’t available.
Common Middle TN Drainage Problems
Standing water in yard after rain: usually grading problems or buried springs. French drain or regrading.
Wet basement or crawlspace: exterior foundation drainage, interior perimeter drain, sump pump, or combination.
Water against foundation: downspout extensions and grading away from house.
Erosion at slopes: swales, riprap channels, retaining walls.
Driveway flooding: channel drains across driveway, French drain along uphill side.
Septic system overload from storm water: divert surface water away from septic field with French drain or grading.

Diagnostic First
Drainage problems often have multiple causes. S and S starts with site assessment to identify:
- Source of water (surface runoff, groundwater, roof drainage, neighbor’s property)
- Existing drainage features and where they’re failing
- Soil type and how it affects drainage approach
- Available outlets for captured water (daylight, dry well, storm sewer)
- Property grade and existing slopes
Bad drainage installs solve one problem and create another. Diagnostic first means the install actually fixes the root cause.

Frequently Asked Questions
How much does drainage installation cost in Middle TN?
Basic French drain: $1,200-3,500. Larger system: $3,500-9,500. Foundation perimeter: $8,500-22,500. Channel drain: $850-2,400. Whole-property redesign: $8,000-32,000+.
Will a French drain solve my wet basement?
Sometimes, depends on water source. Surface water entry: yes, French drain at perimeter helps. Groundwater rising through floor: needs interior perimeter drain + sump pump. Diagnostic determines.
How long do French drains last?
Properly installed with quality filter fabric and clean aggregate: 25-40 years. Cheap installs without filter fabric clog with sediment in 5-10 years.
Can you install drainage to fix basement leaks?
Yes, exterior foundation drainage is the gold standard fix. Interior systems (perimeter drain + sump) work when exterior access isn’t feasible.
Do French drains require maintenance?
Minimal, annual outlet inspection to ensure no blockage. Quality installs with filter fabric don’t silt up.
How long does drainage install take?
Basic French drain (50-100 ft): 1-2 days. Foundation perimeter drainage: 3-7 days. Whole-property redesign: 1-3 weeks.
