Diversified Environmental Field services I Environmental Construction Services
Environmental Construction Services
DEFS’s professional technicians are providing complete phases of construction for Pilot testing, Vapor sampling and Soil Vapor extraction (SVE) or Dual Phase Vapor extraction (DPVE) treatment installations. These phases including but not limited to saw cutting, core cutting, excavation, piping, demolition, backfilling, compaction and surface completion.
We have experience working on a variety of sites, such as active or legacy Dry cleaners, Gas stations, Car washes and other industrial sites which needs environmental field services for their environmental investigations and remediation purposes.
Our Services
Environmental construction services cover a wide range of activities that support
remediation, compliance, and infrastructure related to environmental projects.
These services bridge traditional construction with environmental remediation and
protection.
Site Preparation & Support
- Clearing and grading of contaminated or impacted land.
- Excavation and trenching for utilities, pipelines, and remediation systems.
- Shoring and stabilisation to ensure safe excavation in contaminated zones.
- Containment berms and liners for soil or water control.
Remediation System Construction
- Soil Vapour Extraction (SVE) systems: wells, piping networks, blowers, and treatment units.
- Dual-Phase Extraction (DPE) / Multi-Phase Extraction systems: groundwater and vapour recovery wells, pumps, separators.
- Air Sparging and Biosparging systems: injection wells, compressors, distribution piping.
- Pump & Treat systems: extraction wells, conveyance piping, treatment skids (e.g., GAC, air strippers).
- Chemical injection systems: delivery wells and distribution networks for in-situ chemical oxidation (ISCO) or bioremediation.
Groundwater & Soil Infrastructure
- Monitoring well installation and development.
- Sub-slab vapour mitigation systems (for methane and VOCs under buildings).
- Methane barrier and venting systems (common in California construction).
