Soil and Groundwater Remediation

Excavation and Disposal

Tri-Phase excavates and loads hazardous and non-hazardous contaminated soil and debris for off-site disposal. We have remediated industrial sites, abandoned manufacturing facilities, operating and occupied institutions, high-traffic retail outlets and functioning bulk terminals. As your complete, one-stop shop, we also provide services related to site restoration including backfilling, compaction, grading and landscaping.

Soil Remediation

Depending on our clients' objectives and factors such as soil composition and stratigraphy, excavation and disposal may not be a viable remedial option nor the most cost effective solution. Therefore, our remedial capabilities include the latest in-site and ex-site technologies in treating soil, debris and sludge. We strive to attain the highest standards in this field and continually invest in the very latest plants, equipment and staff training. All our removal staff is highly qualified and trained.

Groundwater Treatment

We bring years of combined experience in the implementation, operation and maintenance of both in-situ and ex-situ groundwater remediation systems. In addition to our MOE Certificate of Approval (C of A) for the handling of PCB waste, we also carry a C of A for our mobile water treatment systems. Furthermore, we construct, operate and maintain extensive groundwater recovery and treatment centres for the treatment of groundwater contaminated with PCBs, heavy metals, arsenic, hydrocarbons and chlorinated hydrocarbons. All mobile and fixed treatment facilities meet the most stringent of standards while satisfying cost, health and safety, quality and environmental objectives.
