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...

Geomembrane Systems for Underwater Repair of Dams

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...

Interaction Between Geomembranes and Granular Materials

Engineered Contaminated Soils and Interaction of Soil Geomembranes
Due to liability issues, landfills are no longer considered the best method of waste disposal. Innovative, safe disposal methods for large quantities of contaminated soils and waste are...

Examination of Performance of a Geomembrane Landfill Cover

Capping with Fiber Clay
Landfill-cap construction is expensive and often results in economic hardship, especially for small towns. Costs for conventional clay or geomembrane caps for municipal solid-waste landfills...

Vacuum-Assisted Consolidation of a Hydraulic Landfill
As part of the Pier 300 42-acre site ground modification project, a field test of vacuum-assisted preconsolidation of hydraulic fill was studied. The objective of the test was to assess...

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...

Permeation of Organic Chemicals Through HDPE Geomembranes

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...

Landfill Liners from Top to Bottom
Since EPA began requiring geomembrane liners in 1982, liner system components have multiplied rapidly. At the same time, there has been a movement toward relatively large, sophisticated,...

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...

Long-Term Durability and Aging of Geomembranes

Geomembrane Construction Quality Assurance

Waste Containment Systems
Construction, Regulation, and Performance
This proceedings consists of papers presented at a symposium on waste containment systems at the ASCE Convention in San Francisco, California on November 6th and 7th, 1990. Geotechnical...

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...
