FOUR PILLARS OF
GEOSYNTHETIC SUSTAINABILITY
Q: How is geosynthetic sustainability as
compared with conventional construction
materials like soil, concrete and steel?
A: The four pillars of sustainability are
human, social, economic and environmental.
Geosynthetics are winners when compared
to conventional alternatives in all four
areas. To substantiate this assertion I would
strongly recommend that you have a look
at the International Geosynthetics Society's
(IGS) website.
https://www.geosyntheticssociety.org/sustainability/
Their website has a section entirely on
sustainability. It is outlined below:
1. Sustainability statement
2. Case studies
3. Paper citations
4. PowerPoint presentations
5. Videos
6. eBooks
The section on sustainability culminates
with the IGS' response to the European
Commission's consultation on Microplastics
pollution. It is very well done and includes a
carbon calculator that can be used to compare
geosynthetic to conventional alternatives.
BRIDGING OR TRAMPOLINING
DURING LINER INSTALLATION
Q: Why is it required that there be no
bridging or trampolining during liner
installation at any temperature?
A: Bridging or trampolining is common
at breaks in grade at most installation,
particularly in cool mornings at a jobsite. If
backfilled in this state, the geomembrane
would be stressed and could yield or, worse
yet, rupture at seams or appurtenances. It is
strongly advised that one does not backfill
trampolining geomembrane. Please consult
EPA/600/R-93/182 document section 3.7.1
" Soil Backfilling of Geomembranes. " It
describes a placement of soil backfilling
that proceeds from a stable working area
in a gradual progression. The soil should
be pushed forward in an upward tumbling
action in " fingers " with controlled slack
being induced into the geomembrane.
If a trampolined area is encountered,
backfilling should cease until warmer
temperatures are experienced and the
geomembrane is in intimate contact with
the underling material.
