Geomembrane solves waterproofing challenge in difficult underground installation

A large Saskatchewan potash mine needed a waterproofing membrane during maintenance on a service shaft that is used to transport personnel and equipment from ground-level to various depths of the mining operation. The site alone posed a number of challenges. It was 1,300 metres below grade and shaft wash water was expected to be entering the area long term, causing erosion problems.
landfill liner

Aquifer recharge rates can affect landfill leachate plume migration rates

Leachate releases at the bottom of waste impoundments are difficult to control and may be active for years, suggesting the need for ongoing management of associated plumes in groundwater. This study examined the effect of recharge to the water table as a component of natural attenuation for stabilizing narrow contaminant plumes from continuously leaking sources.
valve vaults installation

A new approach to construction allows for smaller valve vaults

With the M11 harness, there are multiple areas that can fail, and when failures occur, they are costly. The question that must be addressed is: “How is it possible to economize space in valve vault construction in a way that is both safe and effective?” The answer is to provide efficient thrust restraint for the pressure piping that passes through the vault in a way that does not require a harness.
