DXI’s Environmental Works Packages combine heavy civil engineering with targeted environmental asset management. Built to support the green transition, this unified offering delivers structural resilience and strict regulatory compliance across waste processing, containment, and renewable energy sectors.
1. Waste Treatment Facilities
DXI manages the complex construction and technical modification of modern waste treatment facilities. Our team executes precise bulk earthworks, installs chemical-resistant drainage systems, and pours heavy-duty reinforced concrete slabs engineered for high-impact sorting and recycling operations. We also specialize in live-site modifications—retrofitting older facilities with advanced leachate storage and processing bays to meet changing regulatory demands without halting client operations.
2. Landfill Infrastructure & Lifecycle Engineering
From initial cell design to full ecological reinstatement, DXI provides comprehensive engineering across the entire landfill asset lifecycle:
-
Construction: Engineering secure containment cells utilizing low-permeability clay liners and advanced geosynthetic membranes to completely isolate waste and protect local groundwater.
-
Maintenance: Installing and continuously balancing subsurface extraction networks, including vertical gas wells and horizontal leachate lines designed to accommodate ground settlement.
-
Restoration: Executing permanent containment capping, landscape profiling, and topsoil reinstatement to return closed cells to safe community or ecological use.
3. Wind Farm Civil Facilities Management
Extending our civils capabilities to the renewable energy sector, DXI provides specialized facilities management to secure the infrastructure of onshore wind farms. Remote turbine locations require continuous, proactive maintenance to protect assets and ensure uninterrupted power generation.
Our targeted wind farm interventions focus on long-term structural integrity:
-
Access Track Maintenance: Continuous grading, drainage management, and structural reinforcement of heavy-duty haul roads to guarantee safe passage for heavy maintenance cranes year-round.
-
Erosion & Drainage Control: Implementing sustainable drainage systems (SuDS) and culvert management to mitigate soil displacement and manage surface water runoff around critical turbine bases.
-
Foundation & Hardstanding Integrity: Inspecting and remediating crane pads and turbine foundation surrounds to protect against shifting and structural environmental wear.
