Use of HDPE Telescopic Leachate Shafts for leachate collection and extraction are described and explained.

GCL as an Alternative to a Low Permeability Clay Layer or HDPE Lining Membrane

Mon, 12 Oct 2009 22:47:30 +0000

The choice of Geosynthetic Clay Liner (GCL) may be a great option when the more normal Compacted Clay Liner (CCL) option is expensive or is not readily available in a region. Read about GCLs here!

Fabricated Geomembrane Institute Short Course Available in September

Fri, 04 Sep 2009 12:32:20 +0000

The US Fabricated Geomembrane Institute (FGI) offers its popular short course, "Constructing with Fabricated Geomembranes", on 23 October 2009 in Lakewood, Colorado. Those involved with the design, construction, operation and closure of potable water and irrigation ponds, floating covers, canals, landfills, waste water lagoons, secondary containment, golf course ponds, decorative applications, corrective action activities at closed sites, etc. are encouraged to attend.

Landfill Designers and Specifiers Beware of Blocked Drainage Layer Geotextiles

Mon, 24 Aug 2009 13:34:47 +0000

Inferior geo-composite membranes which should both provide a low permeability membrane to cap a landfill and replace drainage stone otherwise needed above the low permeability layer are being offered which don't do the job. It is essential to drain the interface and prevent development of a slip plane at the membrane on even quite gentle landfill slopes, but slip failures are inevitable if inadequate geo-composites are used. Find out how to avoid this pitfall.

Landfill Engineering and Environmental Conflicts

Fri, 03 Jul 2009 01:35:03 +0000

Landfill engineers are increasingly preoccupied with building landfills which will capture as much landfill gas as possible and use that gas optimally to generate renewable energy. However, this very engineering holds dangers for the environment around a landfill, with raised leachate levels, and extra stress on landfill lining membranes.

US EPA Landfill Capping

Fri, 15 May 2009 23:00:59 +0000

Landfill Capping is the most widespread type of remediation since it is in general less pricey than other technologies and actually manages the human being and environmental risks allied with a remediation place. In this article we provide the basics of capping according to the US EPA.

Landfill Reclamation

Fri, 10 Apr 2009 15:23:44 +0000

Landfill reclamation is a technique which can be very beneficial and profitable to developers in certain cases. To reclaim the land of an old tip returns it to normal use and the land can then be used for housing and factories etc. Read more about Landfill Reclamation in this article now!

How to Do Landfill CQA Up to the Start of the Construction Works

Sat, 20 Dec 2008 01:28:41 +0000

Landfill CQA Actions up to the Start of Construction Once the landfill design engineer has completed the landfill design and the specification has been substantially completed, it is possible to write the landfill Construction Quality Assurance (CQA) Plan, which the construction contractor will then be required to follow, and which will once completed be reported upon [...]

Why Landfill Construction Quality Assurance is so Important to the Installation of Landfill Geomembrane Liners

Tue, 16 Dec 2008 22:04:48 +0000

Landfills nowadays each contain huge amounts of organic materials and hold a huge potential to pollute the local groundwater for generations in the containment systems upon which their design is based fail to function as intended. The engineering of a landfill is no different to other engineered structures, in fact in many ways, especially due to [...]

How to Design a Permanent Geological Exposure in a Landfill

Sun, 14 Dec 2008 20:21:05 +0000

One of the most common locations for landfills are worked out quarries and quarries suitable for landfill are an increasingly valuable resource for this reason. In a growing number of cases suitable sites include rare geological exposures of mineral bearing rock, or strata of regional importance which need to be kept exposed after landfilling for educational [...]
