Solmax

What Solmax does

Solmax (legal entity: Groupe Solmax Inc.) is a Quebec-based, privately held manufacturer of geosynthetics and polyethylene geomembranes serving civil and environmental infrastructure projects globally. The company operates as the consolidated platform formed by the 2017 acquisition of GSE Environmental, the 2020 acquisition of TenCate Geosynthetics, the 2021 acquisition of Propex, and a 2025 acquisition of a South American geosynthetics manufacturer, supported since 2017 by institutional capital from Caisse de dépôt et placement du Québec (CDPQ) and Fonds de solidarité FTQ. Headquartered in Longueuil, Quebec, with manufacturing in Varennes and a presence across more than 25 countries, Solmax sells a portfolio organized under eight proprietary sub-brands: GSE (HDPE/LLDPE geomembranes), MIRAFI (woven/nonwoven geotextiles and the patented H2R*i wicking geosynthetic), FABRINET (protection layers), PROPEX (erosion control systems including Armormax), GEOTUBE (dewatering containers), BENTOLINER (geosynthetic clay liners), MIRAGRID (geogrids for MSE applications), and Petromat (paving interlayers). The portfolio is complemented by free engineer-facing design tools (InfraSolve, MiraSlope Pro) that implement FHWA, AASHTO, HEC-15, and RUSLE methodologies.

Solmax sells through an enterprise field sales model with direct regional offices and a small distributor overlay (e.g., Encon Construction Products in the UK), targeting engineering firms, contractors, government agencies, and infrastructure developers on a project-based, quote-driven basis. Pricing is not publicly disclosed and is determined per specification, volume, and geography. The customer base spans transportation (DOTs, airports, railways), waste management (municipal landfills, hazardous waste sites), water management (reservoirs, canals, wastewater), mining (heap leach pads, tailings dams), energy (district heating pit thermal storage, biogas), and agricultural infrastructure, producing a highly diversified customer roster with no public concentration data.

The company's value proposition rests on three quantified technical outcomes: a 75% lower environmental footprint than conventional construction materials, products engineered for a service life exceeding 100 years, and project-level cost reductions in pavement applications of 20%. Competitive advantages derive from regulatory alignment (EPA Subtitle D/C, CCR, AASHTO, FHWA), a global manufacturing and specification footprint, and a deep branded product portfolio that creates specification lock-in with engineering firms and public agencies. North American engineering operations are concentrated in Georgia (Pendergrass, Cornelia) and Texas, with European manufacturing in the Netherlands and Italy, and Asia-Pacific manufacturing in China and Malaysia, positioning the platform to serve both developed-market infrastructure replacement and emerging-market buildout cycles.

Core offering

Solmax manufactures and sells proprietary geosynthetic products including geomembranes (HDPE/LLDPE), geotextiles, geosynthetic clay liners, geogrids, erosion control systems, and paving interlayers used for environmental containment, soil stabilization, filtration, separation, and reinforcement in infrastructure projects. The company also offers two web-based engineering design tools (InfraSolve and MiraSlope Pro) that integrate AASHTO and FHWA design methodologies to drive specification of its products in transportation, waste, water, mining, energy, and agricultural applications.

Product overview

Solmax operates as a geosynthetics solutions provider offering a comprehensive portfolio of polymer-based engineering products organized under sub-brands. The core offerings include geomembranes (GSE®), geotextiles and wicking geosynthetics (MIRAFI®), protection layers (FABRINET®), erosion control systems (PROPEX®), dewatering containers (GEOTUBE®), geosynthetic clay liners (BENTOLINER®), geogrids (MIRAGRID®), and paving interlayers (Petromat®). These products serve environmental containment, civil infrastructure, transportation, mining, water, energy, and agricultural applications. Complementing the product portfolio are design software tools (InfraSolve and MiraSlope Pro) that enable engineers to design solutions using Solmax products. The company has expanded through acquisitions including Propex (2021) and GSE Environmental (2017).
