EPDM Waterproofing Membrane v/s Other Membranes

A Comparative Analysis of Different Types of Geomembrane

Introduction to Geomembranes

A geomembrane is very low permeability synthetic membrane liner or barrier used with any geotechnical engineering related material so as to control fluid (or gas) migration in a human-made project, structure, or system. Geomembranes are made from relatively thin continuous polymeric sheets, usually in EPDM, PVC, APP & Bituminous Polymers.

You may feel puzzled when thinking that which geo-membrane or simply put which membrane to choose for your water-proofing application. To make the right choice you can go through a comprehensive analysis of these particular membranes to take your pick for the final order placement!

EPDM Membranes

EPDM Membranes are known for their durability factor. They are made from Ethylene Propylene Diene Monomer. They are hugely demanded in numerous industrial and agricultural applications.

PVC Geomembranes

PVC Geomembranes are made from geosynthetic materials with a low permeability. They are hugely demanded for civil and even geotechnical applications.

Other Membranes (APP & Bitumen)

APP Membranes are waterproofing sheets that deal with multilayer applications. The sheeting act as an intermediate layer.

Bituminous Membranes are asphalt instilled sheeting. They even have added modifiers that are used into many business applications.
