LANDFILL CONSTRUCTION
LANDFILL CONSTRUCTION SOLUTIONS BUILT FOR ENVIRONMENTAL SAFETY & LONG-TERM PERFORMANCE
Thalle Construction Company delivers large-scale landfill construction projects that meet the strict environmental, regulatory, and operational requirements of today’s waste management facilities. From new cell development and lateral expansions to closures, capping systems, berms, and leachate management features, we perform every phase with precision and a commitment to long-term environmental protection. Our teams are experienced in building lined containment systems, clay and geosynthetic layers, stormwater controls, access roads, and the heavy civil components that allow landfill operators to safely manage capacity and comply with state and federal regulations.
With a substantial equipment fleet and crews skilled in high-volume earthwork, material placement, and complex sequencing, Thalle excels on large, multi-acre landfill projects where accuracy, safety, and durability are essential. We work closely with owners, regulatory agencies, and environmental partners to ensure quality construction, clear communication, and dependable delivery. Our landfill construction services help communities expand waste management capacity, protect surrounding environments, and maintain safe, stable operations for years to come.

CASE STUDY
NORTH CENTRAL LANDFILL PHASE VI-A & VI-B EXPANSION
Thalle Construction successfully delivered the North Central Landfill Phase VI-A expansion in Polk County, Florida—an ambitious 15-acre Class I landfill cell expansion that strengthened long-term waste capacity for one of the state’s fastest-growing regions. The project required a full suite of heavy civil and environmental construction services, beginning with 75,000 cubic yards of imported subgrade and 90,000 square yards of dual-layer geogrid soil stabilization. Thalle then installed 2.7 million square feet of geosynthetic lining systems, 43,000 cubic yards of drainage sand, and a new stormwater management system designed to perform under Florida’s intense seasonal rainfall conditions.
Key environmental infrastructure included 1,600 linear feet of HDPE leachate detection and collection piping, a new pump station with electrical and instrumentation systems, and a 3,700-linear-foot HDPE leachate force main. Completing this work inside a valley formed by three existing landfill cells—and doing so during Florida’s notorious rainy season—required precise phasing, adaptable scheduling, and continuous water-control efforts. Thalle’s team completed Phase VI-A ahead of schedule, allowing Polk County Waste and Recycling to place the new cell into service earlier than anticipated.
The outstanding performance on Phase VI-A led Polk County to award Thalle a $10.9M change order for Phase VI-B, a 10-acre piggyback expansion directly adjoining the completed VI-A cell. This additional scope reinforced Thalle’s position as a trusted partner capable of delivering reliable, high-quality landfill infrastructure under challenging conditions.
Beyond the expansion work, Thalle was also selected for Polk County’s innovative Wetlands Treatment Construction project, a $11.3 million initiative designed to pilot a sustainable approach to landfill leachate treatment through engineered wetlands. This project included multiple treatment ponds, vertical flow wetlands, free-water surface wetlands, leachate conveyance piping, geosynthetic liners, pumping equipment, mechanical systems, and full electrical and instrumentation controls. While distinct from the landfill expansion, its award underscores the County’s confidence in Thalle’s ability to execute highly technical environmental construction projects.
Together, these projects highlight Thalle Construction’s expertise in landfill development, environmental containment systems, and complex waste-management infrastructure—reinforcing our reputation as a capable, dependable, and innovative partner to municipal clients across the Southeast.
