Landfill Remediation
Using One-Pass Trenchers for Landfills and Environmental Remediation
Hydraulic Barrier (Cutoff) Walls, Collection Trenches, Permeable Reactive Barriers..
DeWind One Pass Trenching has established itself as a trusted leader in providing specialized trenching services for the landfill and environmental remediation industries. DeWind’s innovative approach is redefining the way landfills are managed and remediated – using a variety of advanced techniques designed to ensure safety, efficiency, and environmental protection.
What DeWind Offers
DeWind delivers comprehensive solutions tailored to the unique challenges of landfill management and environmental remediation. These services include:
Hydraulic Barrier (Cutoff) Walls:
Impermeable barriers that prevent the migration of liquids, such as leachate, by mixing native soil with stabilizing agents (bentonite, cement, etc.) directly in situ. We can install with very little room/spatial requirements – landfills usually need cutoff walls right next to the property line or as close as possible.
Collection Trenches:
Engineered trenches that intercept and collect leachate, groundwater, or other contaminants, directing them safely to treatment facilities without the need for traditional open excavations. Minimal to no dewatering required during CT installation. Even if the water table is within a couple ft from the surface – will not impact our installation process.
Permeable Reactive Barriers (PRB):
Systems that allow groundwater to flow through while treating contaminants with reactive materials matched to specific pollutants.
These solutions address complex environmental challenges as well as contribute to safer and more sustainable landfill operations.
How DeWind Does It
At the heart of DeWind’s service offering is its patented One Pass Trenching method. This is a revolutionary technology that delivers multiple benefits by eliminating the need for open excavation. Here’s how it works:
Integrated Installation Process:
The One Pass Trenching system simultaneously removes native soil and places the prescribed backfill or treatment media (whether for a hydraulic barrier, collection trench, or PRB). By using this process, DeWind is able to create a continuous, homogeneous barrier with minimal disruption to the surrounding environment. DeWind creates the least amount of spoils that need to be managed.
In-Situ Soil Mixing:
For hydraulic barrier walls, the system mixes the native soil directly with stabilizing agents. This in-situ mixing technique simplifies the installation process and also preserves the integrity of the site by avoiding the removal of large amounts of soil.
No Open Excavations:
Traditional excavation methods are disruptive and costly, often requiring shoring, dewatering, and extensive spoil management. DeWind’s method completely side-steps these challenges which reduces environmental impact, minimizes downtime, and cuts costs.
Precision and Control:
Advanced controls ensure that each installation meets strict safety and quality standards. By eliminating open excavation, the risk of disturbing hazardous materials or spreading contaminants is greatly reduced.
Why DeWind Excels
DeWind’s unique and innovative approach offers several key advantages – setting them apart from the rest of the industry.
Minimized Environmental Impact:
The One Pass Trenching method significantly reduces disturbance to the surrounding ecosystem by avoiding open excavations. This means less disruption, minimal spoils, and a reduction in the need for site restoration.
Enhanced Efficiency and Safety:
By integrating soil removal and backfill placement into a single pass, DeWind streamlines project timelines while maintaining high safety standards. This efficiency translates into reduced project costs, minimized operational downtime, and a reduction in safety risks.
Long-Term, Reliable Solutions:
Regardless if it’s a hydraulic barrier wall that contains nearby contaminants or a collection trench that manages leachate – DeWind’s installations are designed for longevity. This in-situ mixing technique creates durable, continuous barriers that offer lasting results.
Regulatory Compliance and Low Environmental Impact:
All DeWind installations are designed to meet or exceed local, state, and federal environmental regulations. DeWind ensures that their projects contribute to the overall health and sustainability of landfill sites by working closely with environmental authorities.
