A blog about Landfill Construction Quality Assurance
We will occasionally post capping design information on this blog. We hope that you will find these posts interesting. To guarantee a landfill cap which will drain adequately and for effective gas collection, the landfill cap should incorporate a drainage layer above and preferably also, a gas collection layer below the cap’s low permeability lining system. The [...]
A question for landfill construction quality assurance engineers which arises regularly is whether they should use Triaxial Compression Testing or Direct Shear Testing. Well although triaxial compression testing is the most frequently used small scale direct shear testing does have certain advanatges and can be appropriate under certian circumstances.  There is an interesting dicussion of this issue at [...]
We have been asked where the necessary skills can be obtained for Landfill Construction Quality Assurance work. The core skill needed for Landfill CQA is an good appreciation of soils mechanics, as most of the CQA work relates to civil engineering earthworks, so a good grounding comes from the Soils Mechanics tought within any practically based Civil [...]
The Waste Strategy 2007 has been published, and yes, of course, poor old landfill gets the “worst” (least preferred option) ranking in the waste heirarchy again! Seriously though, there was never going to be any change to the requirements for landfills including the Construction Quality Assurance requirements for landfills, but we thought we would post [...]
