Soil Excavation and Disposal
When a contaminant is accidentally released, soil is usually the first material to be contaminated. The Cannington Group can quickly and accurately make the determination on how best to handle removal of the contaminant and provide the personnel needed to safely and efficiently excavate the materials before transporting for treatment and disposal. We handle both Hazardous and Non Hazardous soils.
The Cannington Group can implement remediation plans for soil and groundwater contaminated with petroleum products, chlorinated and non-chlorinated solvents, heavy metals, PCBs, mercury and hydrocarbons. We have used both traditional remediation methods as well as innovative techniques to ensure our clients of the most cost effective solutions for their projects.
We provide industrial, commercial, and residential services to meet the expectations of our clients.
We provide general earthworks, landfill excavation and cell development, sheet piling, dredging, slope stabilization and much more.
Bio Remediation In-situ & Ex-situ
Our staff have been involved in a number of bioremediation projects across Ontario. Our process uses safe and naturally occurring micro-organisms. These microorganisms breakdown the contaminants found in the soil and change them into harmless products such as water and carbon dioxide. Once the treatment has been completed, the soil can be reused as back fill. Bioremediation can provide significant cost savings compared to disposal.
On-Site Soil Processing
Our On-Site Soil Processes can be very effective in reducing the costly amount of material requiring removal for off-site disposal. In most cases the oversize materials such as rock maybe used as back fill. The process has shown cost savings of 20-30%. An advantage of this system is its size and mobility, which allows us to work in areas where space is at a premium. This process adds yet another methodology to our continuously expanding service offering.
Ontario generates approximately 12-13 million tonnes of non-hazardous solid waste and even with our various recycling programs still more than 10 million tonnes is land filled with over 1/3 being disposed of in the United States. With the border closing, increasing consumption and population rates, difficulty in permitting not only new landfills but also the expansion of existing ones, will exceed our available capacity in the future.
One immediate solution to this problem is landfill reclamation. This remediation technique has already been used extensively in Europe for many years, this remediation involves the excavation of old landfill areas, processing of the waste and cover material, recycling/recovering as much recyclable material as possible to recover valuable landfill space that will extend the life of existing landfills.
This process involves excavation, screening, and/or shredding, removal of recyclable materials, replacement, as well as repacking of waste and cover material to recover valuable landfill space. It involves the use of heavy equipment including track excavators, trommel screeners, waste shredders, mobile conveyors/stackers, wheel/track loaders, and landfill compaction equipment.
