Soil Stabilization (SS)

Rather than excavating and replacing the existing materials, soil stabilization reuses your natural soil or existing foundation. A binder (cement and/or lime) is mixed directly into the soil, which is then mixed, re-profiled and compacted. 

This approach eliminates the costs of excavation, transportation, and material disposal, while significantly reducing construction time.

Soil stabilization is suitable for a wide variety of contexts: municipal roadways with insufficient bearing capacity, temporary access roads for heavy construction, traffic areas for heavy vehicles, remote construction sites, and port infrastructure. 

It is also applicable to contaminated soils, allowing for their on-site reuse rather than costly disposal.

Each project begins with an analysis, formulation, and testing phase in partnership with a design firm to validate the targeted mechanical properties. The treatment is then carried out through mixing: either using pulverizers (pulvo) on-site or Pugmill mixers in a portable plant.

Once the soil has been treated, re-profiled, and compacted, a surface course (gravel, BCR, paving, etc.) is applied to protect the surface.

Yes. Stabilization allows certain contaminated soils to be reclaimed directly on-site, thereby avoiding the costs and constraints associated with their transport and disposal at an authorized site.

This approach is part of a responsible materials management strategy and can result in cost savings depending on the volume and type of contamination. Les Carrières de St-Dominique works in partnership with design firms to ensure that the targeted properties are achieved safely.
