The 12 Québec companies that make up this sector develop innovative and eco-friendly solutions that separate, filter, waterproof, improve drainage, reinforce and distribute loads more efficiently, while protecting soils and surfaces.

Civil engineering involves planning, manufacturing, operating, maintaining and upgrading infrastructure. Most companies in this sector specialize in the production of water dams (cofferdams and anti-spill systems), wind barriers, compost covers, water main rehabilitation ducts (aqueducts and sewers), road grids, landfill membranes and geosynthetic linen. In the environmental sector, companies have developed expertise in the recycling and recovery of post-consumer clothing.

The technical textile materials developed by these companies are mainly anti-root, compatible with drinking water, eco-friendly, waterproof or permeable (depending on the application) and resistant to many elements such as soil acidity, low temperatures, degradation and strength loss caused by chemicals and pollutants in the air or rain and other building materials, erosion, creep and sunlight.

Non-woven, needle-punching, weaving, calendering, direct coating, transfer coating, polymerization and rubber blending are the main processes for producing technical textile materials for the civil engineering and environmental sector. In addition to rolling, value-added coatings are used for finishing high-performance textile products.

Some of the major Québec companies in this sector are Jasztex Fibers, Fybon Nonwovens, Megasecur, Niedner, Soleno Textile, Stedfast, Texel and Texonic.
