Protecting pipelines in mountain areas
Steel transmission pipelines going through mountain areas often face significant risks during their construction and service life. One of the biggest challenges is to protect the pipe and its external coatings against mechanical damage from impact and penetration. Vlad Popovici, writing in Pipelines International, looks at how pipes are protected, including through the use of nonwoven geotextiles.

Assessment of Some Hydraulic Properties of Slime Slurries from Sand Mining Pits Using a Modified Triaxial Cell
The generation of massive volume of slimes from sand mining industry ascertains the need for effective waste treatment. The application of slimes in landfill barrier construction works has been identified as one of the processes that can be used to reduce their volume, enabling in this way the rehabilitation of dangerous sites. This article presents a modified triaxial cell specially built to investigate high water content soils and discusses the results obtained from the investigation of the hydraulic properties of two slimes. The results of laboratory filter cake tests show that the slimes have reasonably good sealing capacities due to the formation of a cake layer on other porous materials upon draining. A relatively low hydraulic conductivity (1.5–3 × 10−9 m/s) was achieved, once the cake layer was formed. This is close to the prescribed 1 × 10−9 m/s required by the local environmental governmental authority for a landfill hydraulic barrier material, indicating their potential suitability as landfill barrier.

Global Acid Rock Drainage (GARD) Guide
The International Network for Acid Prevention (INAP)--an organization of international mining companies--is dedicated to reducing liabilities associated with sulphide mine materials such as acid draiange. INAP is now promoting its Global Acid Rock Drainage (GARD) Guide, which was launched at the Eighth International Conference on Acid Rock Drainage held in Skelleftea, Sweden. The guide describes proven techniques for characterization, prediction, monitoring, treatment, prevention, and management of drainage produced by sulphide mineral oxidation, called "acid rock drainage" (ARD).

How to nail a steep problem
In 1996, a significant quantity of oil spilled near Milford Haven oil refinery when a ship ran aground. Today, measures are being taken to guard the refinery area against oil spill disasters with the installation of geosynthetic containment berms. Geomembranes, geotextiles and geocells are being installed. Read about it in Construction News UK.
