A blog about Landfill Construction Quality Assurance
Dense Asphaltic Concrete has been as a Landfill Lining membrane material for many years and although it is not commonly seen in the UK, it is used much more often in Europe, and particularly in Germany.
The Dense Asphaltic Concrete is formulated in a manner which ensures both very low permeability and possibly as low as 1 x [...]
Summer 2007 saw the environmental engineering consultants Enviros Consulting return to Wexford County Council’s Killurin Landfill Site, for further capping and restoration works.
This year sees the penultimate stage, of a 4 year involvement of Enviros with local authority Wexford County Council at this active domestic waste Landfill site.
Wexford originally commissioned Enviros back in 2004 to [...]
The purpose of Landfill Construction Quality Assurance is to ensure that the landfill is constructed in full compliance with the specification. The primary responsibility for ensuring this, rests with the landfill construction (civil engineering) contractor. The CQA Engineer (provided by Rowe Environmental), on site, provides independent inspection and verification of the work, and receives all the [...]
The widely used definition of geophysics is that provided by Sheriff in the Encyclopedia of Exploration Geophysics.
For the purposes of this site, we refer more specifically to the following definitions – these focus on Environmental and Engineering Geophysics:
Geophysics is: The subsurface site characterization of the geology, geological structure, groundwater, contamination, and human artifacts beneath the Earth’s [...]
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 geosyntheic “Pozidrain” may [...]
