Whether you’re in the field or in the office, you can quantify the thickness and cost
savings of using Tensar® TriAx® Geogrids with the Subgrade Improvement Slide Rule.
This simple and precise tool shows solutions for a wide range of real-world, soft-soil
scenarios. It also features a cost analysis function that lets you make bottom-line
economic comparisons of stabilized and unstabilized solutions. We also offer a pocket
card that allows easy estimation of subgrade soil strengths and aggregate thickness
requirements. To order your free slide rule and pocket card, call 800-TENSAR-1 or
contact your local Tensar Geogrid representative.

IMPROVE SITE ACCESS. Tensar TriAx
Geogrids help you get onto the site, even
with bad weather or poor soil conditions.
On sites you can barely walk on, simply roll
out the geogrid and push out a layer of
aggregate. Now you’ve got a firm, freedraining platform or a reliable access road.
With TriAx Geogrids, bad sites and poor
weather won’t be a challenge anymore.
REDUCE CUT AND FILL. Removing bad
soils is getting more and more expensive.
Contaminated areas require special (and
costly) disposal. Now you can work on
top of weak soils by adding a layer of TriAx
Geogrid and aggregate fill. The result –
less undercutting, backfilling, and disposal
costs. And don’t forget, Tensar International
has the experience to help you determine
the right fill thickness for your projects.
REDUCE AGGREGATE FILL THICKNESS.
In test after test, Tensar TriAx Geogrids
have proven their value by enabling a thinner,
stabilized aggregate fill layer to have the
identical bearing capacity and serviceability
as a thicker, unstabilized aggregate fill
layer – or even a layer with a fabric under it.
A reduction in aggregate thickness can be
achieved through the use of TriAx Geogrids,
with no change to the road’s performance.
VALUE ENGINEER FOR PROFIT. You can
Value Engineer (VE) for profit by using TriAx
Geogrids to construct thinner fill layers.
When curbs determine the final pavement
grade or existing utilities limit undercutting,
it is possible to construct a reliable but
thinner base course without sacrificing
durability and without expensive
reconstruction or utility re-routing.
