Projects
We specialize in environmental cleanup and excavation primarily for commercial and industrial clients — demolition, installation of petroleum tanks for service stations, construction of service stations from scratch, cleanup of hazardous materials from carwashes, and environmental cleanup work for municipalities and townships across Ontario. We take pride in our cleanliness on a jobsite, and in safety standards we set exceptionally high for ourselves.
401 Eastbound Service Centre
The scope of work pertained to the decommissioning, demolition, and remediation of a service station and adjacent buildings.
Clarkway Construction utilized its ALLU Bucket (crusher/screener) to reduce demolition debris, screen debris from the soil, and crush frozen material suitable for backfill. During remediation procedures, the crusher/screener allowed frozen clean native material, otherwise suitable for backfill, to be crushed and screened for optimal compaction.
Contaminated groundwater was found during drilling activities; Clarkway Construction activated the certificate of approval for our water treatment system to treat and discharge the impacted water to an adjacent surface watercourse.
401 Eastbound Service Centre
The service centre and adjacent restaurants were decommissioned and demolished. An estimated 6,000 metric tonnes of soil was anticipated to be contaminated with hydrocarbons; well reports determined groundwater was contaminated with SVOCs, VOCs, BTEX, and hydrocarbons. Clarkway Construction performed all work in conjunction with the environmental consultant retained by the client.
Clarkway Construction utilized ORC (Oxygen Release Compound) as a method of in-situ remediation. An estimated half of the contaminated soil originally arranged for off-site disposal was made suitable for backfilling purposes instead.
Clarkway Construction activated the Certificate of Approval for our water treatment system. Impacted groundwater was treated and dispersed to an adjacent surface watercourse.
