Five major considerations when designing geomembrane mechanical attachments
September 18th, 2023
By Felon Wilson The terms attachments, penetrations and terminations are often considered synonymous, or at least in the same family, when used in the context of geomembranes. This post will focus on attachments and specifically a review of ASTM D6497, one of the main guides for geomembrane mechanical attachments. ASTM D6497 (General Practices for Geomembrane […]

Three cost savings geomembranes provide in potable water
September 8th, 2023
By Felon Wilson Resiliency in drinking water systems has become a broad discussion as many systems have experienced operational and quality problems. Like much of our ageing infrastructure, the backlog of needed updates and repairs continues to grow. Infrastructure improvements are expensive, and the cost burden of the improvements is borne by the user, in one […]
Geomembranes for beginners
September 7th, 2023
Geomembranes are low-permeability synthetic membrane liners or barriers formed into sheets used as a barrier to control or mitigate fluid and gas migration into the soil. Common applications of geomembranes include landfills, pond liners, dams, erosion control, sediment control, landfill liners, landfill covers, and for the mining industry among other applications providing a barrier between […]
Mercurial matter: Puzzling out PFAS removal in landfills
August 1st, 2023
A contaminant whose importance appears to have grown significantly in recent years, poly- and perfluoroalkyl substances (PFAS) present a challenge to pollution management given their apparent toxicity – although a clear picture is still emerging – and persistence. The tag “forever chemicals” is clearly very appropriate for a class of synthetic compounds whose unusual molecular […]
Lining a tailings facility on the roof of the world
July 10th, 2023
Solmax geomembranes were used to line the tailings facilities of the recently expanded Yulong Copper Mine. The mine located in the Qinghai-Tibet Plateau, on one of the largest copper deposits in China and is important to the economy of the region. The mine is located in some of the highest elevations in the world. The […]
How to attach and terminate geomembranes on a concrete structure
June 15th, 2023
HDPE and LLDPE geomembranes are commonly utilized as barriers and covers in various containment facilities, including solid waste landfills, liquid containment areas, mining ponds, agriculture, and aquaculture ponds. The connection of geomembranes to concrete walls and ancillary structures, such as pipe penetrations or outlet structures under hydraulic pressure, plays a crucial role in ensuring proper […]

Geosynthetics in Low Impact Development
May 15th, 2023
Traditional stormwater systems throughout the country are aging. Meanwhile, municipalities are struggling to find cost-effective means of managing wet weather events. Traditional stormwater systems collect rain and/or snowmelt and carry it via piping networks to a nearby waterway, or wastewater treatment plant. In cases where stormwater is delivered directly to waterways, pollutants can be carried […]
