Why Northex Needs to Receive Environmental Studies of Your Soils

Northex is a treatment facility, not a landfill: we must know the composition of the soils and the nature of the contaminants to ensure we can treat them according to our authorization certificate, accurately assess their potential for recovery, and determine our pricing.
The studies we receive are analyzed by our team of experts and handled with strict confidentiality.

Does Northex’s Site Have a Truck Scale?

Yes! We ask that you notify us 48 hours before delivering your soils to ensure there is no waiting time during unloading. This benefits the transporters, you, and our organization.

What Is the Turnaround Time for Receiving a Quote?

The usual response time is one or two days after receiving the environmental studies.
This allows our team to assess the soil composition and associated contaminants.
However, we can expedite this process if you inform us of your urgency: we adapt to your needs.

Trace Québec and Transport Manifests

Once our quote is accepted, we will provide you with our site number for “Trace Québec” and the transport manifests to present when unloading your soils. We are available at every stage of your project to support you.

How Is This Different from a Landfill?

We treat and recycle the soils to give them a second life, allowing our clients to reuse our processed products for their future needs. Additionally, the fees for contaminated soils leaving their original site, effective January 1, 2024, are only $5/ton with us, compared to $10.67 for landfills and waste disposal sites.
