A blog about Landfill Construction Quality Assurance
We explain why the landfill CQA engineers involved in CQC and CQA hold a such a vital role as the final link in ensuring that the landfill design is constructed to the specified requirements. CQ Engineers never forget! Future generations depend on you!
Use of HDPE Telescopic Leachate Shafts for leachate collection and extraction are described and explained.
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!

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.
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.
