First, polyester resin is passed through
a compress cylinder to make a flat bar which is then frozen
and processed into strips through spunbond. These strips are
put into a grid pattern and laser or other types of welding
finally create a combined stiff geogrid.
How it was developed
Geogrid is widely used as a reinforcing agent in construction
works for soil reinforced retaining walls, banking slopes,
soft ground etc. However, the test period during which geogrid
is used in construction structures is usually not long enough,
leaving uncertainties regarding installation resistance of
geogrid as a long-term reinforcing agent.
In addition, hardening of backfill on geogrid during the reinforcement
process can have a huge impact on the long term stability
Specifically, damage to geogrid is very likely given that
decomposed granite soil-often used to reinforce buildings-contains
TOTOGRID is the solution to these problems and helps to construct
stable reinforcement structures.
