Geomembrane Landfill

Geomembrane Landfill – Geomembranes are crucial components in modern landfill design, primarily used to prevent leachate from contaminating groundwater and to control gas emissions.A geomembrane is a synthetic, waterproof barrier used to control fluid or gas migration in the environment. It is typically made from high-density polyethylene (HDPE) or linear low-density polyethylene (LLDPE) resins and is designed to prevent soil and groundwater contamination from hazardous substances.

Here are the key aspects of using geomembranes in landfills:

# Functions of Geomembranes in Landfills

1) Barrier to Leachate
Geomembranes act as an impermeable barrier, preventing leachate (the liquid that percolates through waste) from seeping into the soil and groundwater.

2) Gas Containment
They aid in regulating the outflow of gases produced by the breakdown of organic waste, including methane.

3) Protection of Surrounding Environment
By containing leachate and gases, geomembranes protect surrounding ecosystems and human health.

# Types of Geomembrane #

1) HDPE

  • Resistant to chemicals
  • Resistant to UV rays
  • Hold long
  • Commonly used in garbage dumping and mining applications

2)  Linear Low-Density PolyEthylene (LLDPE)

  • flexible
  • Resistant to chemicals
  • Used in applications that require flexibility and elongation

3) Polyvinyl Chloride / PVC

  • Flexible and easy to install
  • Used in applications requiring low permeability
