Elva-Block is a technical membrane fabric specifically designed for liquid containment and control. The heavy-duty reinforced construction provides excellent strength but the key benefit is in the formulation. Using the proven Dupont Elvaloy technology, Elva-Block offers exceptional resistance to oil, fuel and chemicals. Typical applications include; bunding and capping used in spill control, non-potable tank lining and chemical resistant covers.



  • Elvaloy Technology: Provides exceptional resistance when exposed to oil, fuel and most harsh chemicals.*
  • Encapsulated Edges: Ensure liquids cannot wick along the polyester base cloth, affecting the physical integrity of the fabric.
  • Embossed Surface: The top side is finished with an embossed finish offering a slip resistant surface.
  • Heavy Duty: Manufactured with a high tenacity polyester yarn and coated with a specific formulation. This construction provides strength, puncture and abrasion resistance.
  • UV Resistant: Developed to withstand the harsh Australian outdoor conditions.
  • Easy to Fabricate: Can be thermal or high frequency welded and has excellent lay-flat characteristics for ease of fabrication.
  • Anti-microbial: Does not support the growth of bacteria which is particularly beneficial when used in treatment ponds.
  • Dimensional Stability: Minimal expansion and contraction which minimises wrinkles and installation issues.
