Landfill Closures

Turnkey landfill closures: final cover, geosynthetics, stormwater, and CQA—built for compliance and long-term performance.

Closing waste cells the right way—safely, compliant, and built to last.

Davis & Sons delivers turnkey landfill closures across Northeast Tennessee and Southwest Virginia, combining heavy civil earthwork, geosynthetics installation, stormwater controls, and CQA documentation so owners can meet permit conditions and transition smoothly into post-closure care.

Landfill Closures & Final Cover Systems

What we build

  • Final cover systems (soil/geomembrane/GCL composites) that minimize infiltration and resist erosion. eCFR
  • Gas management features (vents, trenches, header tie-ins) coordinated with your GCCS plan. US EPA
  • Run-on/run-off & stormwater controls: down drains, channels, perimeter ditches, energy dissipation, and permanent BMPs. Tennessee State Government
  • Surface protection & vegetation: topsoil placement, lime/fertilizer specs, seed mixes, and stabilization per the TN EPSC Handbook. TNEPSC

Typical scope (turnkey or à la carte)

  1. Pre-construction – survey control, phasing, traffic plans, safety and SWPPP setup. TNEPSC
  2. Grading to design – shaping waste mounds, interim cover repairs, anchor trenches.
  3. Geosynthetics – geomembrane and/or GCL placement, seams, panels, and tie-ins at penetrations. DWEE NE
  4. Drainage layer & gas features – geocomposite, sand, vents, and riser details.
  5. Protective/erosion layer – cover soils, ESC measures, down drains, aprons. Tennessee State Government
  6. Topsoil & vegetation – soil amendments, seeding, mulching, and punch-list stabilization. TNEPSC
  7. CQA/CQC & as-builts – density tests, seam testing (air-channel/vac box), panel layout logs, and survey deliverables. EPA NPLSems Publishing

Compliance you can point to

  • Subtitle D closure criteria (MSWLF): written closure plan, final cover meeting permeability and erosion performance, and closure completed within 180 days of initiation (unless an approved extension applies). eCFR
  • Post-closure care: maintain cap, leachate, groundwater, and methane systems; typical 30-year duration (state director may shorten/extend). US EPAUS EPA
  • Tennessee program: closure/post-closure plans must be submitted/approved under Rule 0400-11-01; certifications follow TDEC SOPs. Tennessee State GovernmentTnSos Publications

How we reduce risk

  • Mountain-tested logistics: safe access on steep grades and limited-footprint work areas.
  • Weather windows & phasing: flexible sequencing to protect subgrades and liners during wet spells.
  • Constructability input: early reviews of slopes, anchor trench details, stormwater conveyance, and tie-ins to existing infrastructure.
  • Third-party ready: we collaborate seamlessly with your engineer and independent CQA to keep closeout moving. EPA NPL

Project types we support

  • MSW landfill parcels and piggyback cells
  • C&D monofills and industrial cells
  • Partial closures, final closures, and corrective action caps
  • Repairs: erosion fixes, down-drain replacements, cap penetrations

Deliverables

  • CQA documentation set (testing, seam logs, panel maps) and as-built survey
  • SWPPP records and stabilization certifications per TN EPSC guidance
  • Owner training for post-closure inspections and routine maintenance tasks TNEPSCTennessee State Government

Service area

Tri-Cities and the I-81/I-26 corridor—Kingsport, Johnson City, Bristol, surrounding counties, and nearby Southwest Virginia.

FAQs

What standards do your caps meet?
We build to the engineer’s design and 40 CFR 258.60 performance requirements for infiltration and erosion control. eCFR

How long is post-closure?
Federal guidance is 30 years, adjustable by the state director based on site conditions and performance. US EPA

Do you handle CQA and as-builts?
Yes—our teams work with your independent CQA to generate complete testing records and as-built packages per EPA guidance. EPA NPL

Call to action

Ready to plan a closure phase?

  • Request a scope review (closure plan, phasing, geosynthetic specs, stormwater).
  • Schedule a site walk to discuss access, sequencing, and weather-risk strategies.
  • Ask dispatch about pairing trucking with cover-soil sourcing to keep cycles tight.
