VLDPE Waterproofing Membranes

VLDPE waterproofing membranes are flexible, durable sheets made from Very Low-Density Polyethylene (VLDPE) used to create waterproof barriers in construction, landscaping, and environmental containment. They’re a subtype of polyethylene membranes, engineered for superior flexibility, elongation, and chemical resistance.

Overview of Corex VLDPE

Corex® VLDPE sheet is a waterproofing membrane made with a formulation based on very low-density polyethylene giving it excellent flexibility and weldability.

Used in applications requiring high elongation and ductility. This product has high chemical and tear resistance.

What is VLDPE?

VLDPE stands for Very Low-Density Polyethylene, a type of polyolefin with a lower density and higher branching than standard LDPE (Low-Density Polyethylene). This molecular structure gives it:

  • Excellent flexibility and stretch
  • High puncture resistance
  • Low permeability to water and gases

Order VLDPE sheets and rolls in bulk starting from 4 tonnes.

Variants

  • Material options – VLDPE, LDPE, HDPE, TPE
  • Thickness – up to 3mm
  • Width – 2050mm wide
  • Finish – Mono layer, and Co-extruded (2 sides) with single layer

Benefits

  • Waterproof: Prevents water ingress or escape
  • Flexible: Conforms easily to irregular surfaces or contours
  • High Elongation: Stretches under stress without cracking or tearing
  • Chemical Resistant: Withstands acids, salts, and hydrocarbons
  • UV Resistant (with additives): Can be stabilised for outdoor exposure
  • Environmentally Safer: Preferred over PVC due to lower chlorine content

Applications & Industries

  • Contruction: Below-slab membranes, foundation waterproofing
  • Landscaping: Pond liners, retaining wall barriers
  • Agriculture: Canal liners, silage pits
  • Mining & Industry: Secondary containment, leachate barriers
  • Environmental: Landfill liners and caps, groundwater protection
