Powering Your Electric Vehicle: Affordability Starts with Properly Engineered Geomembrane Liner Systems
Lithium is a vital battery component, and lithium-ion batteries are especially interesting because in addition to being rechargeable, they present a high-energy density and low self-discharge, which means...
Revolutionizing Containment Applications: Geosynthetics are Amazingly Good, But Not Magical
Geotextiles and geomembranes have been around for more than 40 years and geosynthetic clay liners (GCLs) for more than 25 years. During that time, they have revolutionized the containment of fluids. Their...
Putting On Your Safety Cap
Geomembranes are an important part of landfill cap design. However not all geomembrane liners are created equal, and it's best to know what a liner is made of before specifying...
The Evolution of Geosynthetics
Although the geosynthetics industry only began in the 1960s, it roots can be traced to the earliest humans. Soil stabilization, soil reinforcement, liquid drainage and leak proof barrier...
Underwater Magic
Applications of geomembrane systems to arrest concrete deterioration and control leakage in hydraulic structures have been accomplished, with a few exceptions, in a dry environment by...
Detecting Leaks in Geomembranes
A field-tested leak-location survey, now commercially-available, can provide construction quality assurance or solve a leakage problem in lined landfills, impoundments or tanks. A liner...
Performance of Horizontal and Vertical Barriers
Horizontal and vertical barriers have been used on transportation facilities to control expansive soils and minimize their damages. The effort is to minimize moisture change in the soil...
Long Term Durability of Geomembranes
The most frequently asked question about geosynthetic materials is how long they will last. Precise answers, especially for geomembranes, elude researchers as well as manufacturers, design...
Seam Examination
Charron discusses the importance of seam sampling in geomenbrane installation. In 1988, about 30 million mi of polyethylene geomembranes were used to line landfills, liquid impoundments,...
Construction Quality Assurance for Geomembranes
The results of and lessons learned from construction quality assurance (CQA) programs on 19 geomembrane liners are presented. The specifications are generally exceeded by comfortable margins...
Geocomposites Simplify Methane Barrier/Venting System Design
A case history describing the use of a geomembrane and geocomposite to simplify the design of a combined subsurface barrier and venting system is presented. The passive barrier and venting...
Geosynthetic Shields For Dams
A series of large dams in Europe, waterproofed by geosynthetics, may become U.S. prototypes. In Europe, the faces of more than 30 large dams now contain geotextiles and geomembranes. In...
Geosynthetics in the NATM Tunnel Design
This paper describes the Design Methodology for the New Austrian Tunneling Method (NATM) with special emphasis on the geotextile and geomembrane commonly used in the waterproofing design...
Use of Geomembranes in Deep Valley Landfills
The installation of geomembranes (synthetic liners) under deep valley landfills of utility and mine waste presents unique problems. Limited data are available concerning geomembranes beneath...
Geosynthetics Unearthing New Applications
Geosynthetics are now a $700 million industry. Called geomembranes, geotextiles, geogrids and geocomposites, geosynthetics complement or replace geotechnical designs. Five case studies...
Construction Guide Liners
Geomembrane liners for waste construction require meticulous construction, monitoring and weather watching. With much concern over the longevity of geosynthetics, many overlook the extreme...
Geomembrane Liner Performance in the Arctic
A geomembrane liner must be selected not only on the basis of its chemical compatibility with the substance to be contained, but also on the basis of its physical performance characteristics...
