Construction and housing

RSI Environmental’s services meet the highest requirements in soil remediation and site waste management. The use of its highly efficient technology makes the treatment and recovery of waste from construction sites, residual materials and building materials possible; even when highly contaminated.

Sometimes, it is during the soil characterization phase that problems arise. Such as during excavation work, when unpleasant things are uncovered or during Environmental Site Assessments of a site which may reveal the presence of contaminants.

We work closely with firms specializing in site remediation on residential, commercial and industrial sites in offering our services in construction debris and contaminated soil disposal, which provides them with the opportunity to recycle the waste into something such as clean backfill soil.

Preliminary Environmental Assessments

Today, the majority of construction projects begin with a Phase 1-Environmental Site Assessment. This step is now required by financial institutions before issuing a mortgage loan involving a multi-unit residential building or a building of commercial or industrial use. Phase 1 involves, among other things, a soil test to set the environmental history of a property. Its objective is to verify whether the proposed activities on the site may cause soil and groundwater contamination.
If the phase 1 assessment reveals the presence of actual or potential contamination, a Phase 2-Environmental Site Assessment will take place to provide further and more detailed analyses of the site. If necessary, a Phase 3-Environmental Site Assessment will be used to evaluate the extent of contamination as well as the types of contaminants. Often the offsite disposal is preferred because of the risk of spreading toxic contaminants is higher during onsite work.

In addition to soil characterization, sometimes it is during excavation work when bad discoveries are made. It is possible that while digging, used bunker or oil storage tanks oil tanks, contaminated steel drums, creosote-treated wood, iron rebar, car parts and other debris or residues are found. This may have been the result of what is known as a “scrapyard” in Québec, or an illegal dumpsite.

RSI Environmental for soil remediation

This is where the expertise of RSI Environmental come in play. Once soil characterization is complete, RSI Environmental goes and collects the contaminated soil and other materials and brings them to its treatment facility in Saint-Ambroise. All of the services are offered under one roof with no extra fee. A certificate of destruction is then issued and the construction site is now ready to be filled with a backfill soil free of contaminants.

RSI Environmental provides a solution for the recovery of contaminated soil in Québec, using high temperature thermal desorption (HTTD). This cleaning technique removes more than 99.9999% of contaminate from the soil.

Our facility receives up to 100 000 tonnes of contaminated soil each year as well as any related harmful waste and construction debris. RSI Environmental takes care of sorting the construction debris and recovers it at no extra charge.
