Water containment and civil works projects in the Dominican Republic require insulation that can withstand years of Caribbean sun without becoming brittle. This HDPE geomembrane —also called a liner or impermeable sheet— is manufactured by Moltexo with professional-grade virgin resins, in a range of gauges from 400 to 8000, and designed for serious, long-lasting work: never as a temporary solution.
Key Benefits
- Total impermeability: Dense molecular structure that blocks the passage of water and contaminating fluids, ensuring watertightness in ponds, canals, and foundations.
- Verified UV resistance: Carbon black content of 2.0 to 3.0% (ASTM D1603) to withstand years under direct Caribbean sun without degradation.
- Mechanical durability: Excellent tensile, tear, and puncture performance according to ASTM D6693 Type IV, D1004, and D4833, adapting to slight ground movements.
- Careful Moltexo manufacturing: Professional-grade virgin polymer, controlled production processes, and verified ASTM tests for each gauge.
- Inert material: Suitable for aquaculture, fish farming, and potable water storage, without toxic migration.
Typical Applications and Uses
- Lining of artificial lakes, agricultural reservoirs, fish ponds, and water storage tanks.
- Waterproofing of cisterns, irrigation canals, and drainage trenches on farms and agro-industrial projects.
- Secondary containment in industrial fuel or chemical tanks.
- Landfill sealing and vapor barrier in foundations and concrete slabs.
Quality and Durability
Each variant has internationally referenced ASTM tests: 800% elongation at break (ASTM D6693 Type IV), ESCR stress cracking resistance of 300 h (ASTM D5397), and 50% OIT retention after 1600 h of UV aging (ASTM D3895 / D5885). This is the technical level that separates a long-life liner from a generic black plastic for temporary use. Moltexo also controls the minimum individual thickness with a -10% tolerance on each roll, a requirement that simply does not apply to low-cost materials.
