P.E., Geosynthetic Specialist for Contech Construction Products and
John Kanet, Southwest Regional Manager of Tensar Earth Technologies
gave a slide presentation to an audience of about 40 on the utilization
of Tensar Biaxial Geogrids to stabilize soft subgrades under buildings
and pavement areas including parking areas, roads, etc.
the speakers, the Tensar Biaxial Geogrid:
and drawn from High Density Polyethylene (HDPE) or copolymer sheets,
similar to the way expanded metal is made from steel plates.
is easy to
install without any equipment, just hand-carry and hand-roll it
comes in 3
m or 4 m (10 ft or 13 ft) wide rolls
is an alternative
to chemical stabilization and more permanent
pavement subbase aggregate thickness from 12" to 8".
but does not separate subgrade materials whereas geotextiles separate
but do not reinforce
soft surfaces such that heavy equipment can start driving immediately
