EPT introduces new string-reinforced LLDPE geomembrane
December 13th, 2018
To meet the growing demand for linear low density polyethylene (LLDPE) by geomembrane fabricators and installers, Engineered Polymer Technologies (EPT) has announced a new string-reinforced LLDPE fabric. LLDPE has been in increasing demand due to its superior flexibility and better layflat versus high density polyethylene (HDPE). EPT has specially formulated its LLDPE fabric for high […]
Automation of large-scale geotextile and geomembrane fabrication
October 1st, 2018
The development of a large-scale fabrication machine was conceived during the fabrication of geotextiles for a tailings pond cap in 2010. The machine joins five strips of material at a time to create fabricated panels for large projects. It is capable of both welding geomembranes and sewing high-strength geotextiles. This machine was specifically designed to […]
Don’t be afraid of making horizontal geomembrane seams on side slopes
August 1st, 2018
Over the years, there have been many discussions raising concerns about having geomembrane field seams located horizontally on side slopes. By not allowing such seams, it usually results in many short roll lengths that become either unused or difficult to tailor into the flat area of the project. Stated differently, the installation costs increase accordingly. […]
The durability of exposed geomembrane covers
October 1st, 2017
The most frequently asked question by people in the geosynthetics world is how long is the anticipated lifetime of geosynthetics. So much so that of the more than 3,000 questions submitted to the GMA Techline since it began in 2004, 591 (19.7%) have been on lifetime, aka durability. Of these, 49% were on buried lifetime, […]
