Context

Unstable storage space in a sawmill.

Located in La Baie, Saguenay, Groupe Lignarex is a family-owned company specializing in wood transformation for five generations. To meet increasing demand, the company needed to expand and optimize its storage and loading area. However, the site presented significant challenges due to unstable soil composed of wood chips, bark, and other organic residues accumulated over time. This instability hindered accessibility for transportation and wood storage operations.

Challenges

Optimizing limited storage space

Prior to Soleno’s intervention, the Lignarex yard suffered from subsidence problems, limiting storage space, which was already limited in the sawmill yard. The soil, enriched with non-structural organic matter, made it difficult to circulate heavy machinery and store lumber. The yard’s limited space, combined with the impossibility of effectively using its entire surface area, represented a major impediment tot hte development of operations.

Permanently stabilize the soil, despite the site’s history;
Allow asphalting of the surface for efficient logistics operations;
Offer a long-lasting, maintenance-free solution

Solution

A combination of geosynthetics to the rescue

Soleno proposed a combination of separation geotextile and BX-2000 reinforcement geogrid, providing effective soil stabilization with low backfill. This solution was deployed over 2 phases, providing Lignarex with a solid yard.

The results were impressive:

Enhanced Stability: The yard has remained stable for over four years without any signs of subsidence.
Improved Accessibility: The asphalted surface facilitates the movement of heavy machinery and transport vehicles, streamlining operations.
Optimized Space: The entire yard area is now fully functional, maximizing storage capacity.

In addition to the products’ performance, Lignarex praised the quality of the advice and follow-up provided by the Soleno team throughout the project.
