The body of work presented in this Thesis document provides a comprehensive
examination of final cover design for municipal solid waste landfills. Accompanying general
design principals is the investigation and resulting recommendations for issues specific to the
closure of the Vancouver Landfill. The first objective of the Thesis was to develop a set of
physical characteristics for soil materials, which would allow for the construction of a lowpermeability
barrier layer meeting British Columbia guidelines. The second objective was to
then use the developed soil criteria to evaluate the suitability of Lower Mainland soils. The
physical characteristic of soil material, originating from trench excavations in Vancouver,
was closely examined and the material evaluated for use in all layers of final cover design.
The last objective of the Thesis was to investigate the use of alternative cover materials,
including geosynthetics, in final cover design. The combination of a comprehensive
literature review and the implementation of a program of soil sample collection and analysis
allowed for the completion of the above objectives. Testing of soil samples included the
determination of the grain size distribution to the clay fraction level. The major findings of
the work are that soil sources in the City of Vancouver are not suitable for use in the
construction of a low-permeability barrier layer. Suitable soil sources however, can be found
in areas of Surrey and Langley. Trench excavation soil is recommended for use in the
foundation layer of the final cover. Lastly, geosynthetic materials are a viable alternative to
the use of soil in final cover design. A polyvinyl chloride (PVC) geomembrane would be the
most suitable geosynthetic based barrier layer for the requirements of the Vancouver
Landfill.
