Heavy-duty stockpile tarps for bulk materials
For over 15 years, Mégatex has specialized in manufacturing heavy-duty waterproof tarps designed to protect outdoor bulk material stockpiles.
Whether for ores such as coal, ferrosilicon, mineral concentrates, zinc, ferromanganese, bauxite, or quartz; for salt, gypsum, fluorspar, grain, or sugar; or even for waste and contaminated soil, our protective covers for bulk materials ensure reliable protection against the elements, moisture, and contamination.
Built for demanding environments, these waterproof tarps are custom-made to fit the exact size and shape of your stockpile, ensuring complete and reliable coverage. Whether you need huge waterproof tarps or tailored solutions, our products deliver long-lasting performance in industrial settings.
Comprehensive support, from calculations to installation
In any stockpiling project, every moment counts. Bulk piles often need to be covered quickly to prevent contamination, material loss, and production downtime—a challenge we fully understand and are specifically organized to address.
Mégatex supports you at every stage of your project:
- Analysis and measurement — our team helps you determine the exact dimensions of your pile, even when its geometry is complex or irregular.
- Custom calculation and fabrication — we design and manufacture your covers to the precise dimensions of your stack, ensuring optimal coverage with no material waste.
- Installation type recommendation — based on the planned storage duration, climatic conditions, and the site, we propose the most suitable anchoring and installation solution.
- Rapid on-site installation — our team travels to install your canvases promptly, with the commitment to safety and durability that defines our work.
The result: a project managed from start to finish, without you having to deal with multiple suppliers or improvise a solution in a rush.
