Slide 9
The job of the Civil Engineer is to plan, slow down, and even
STOP! the rock/soil from moving in areas where people live and
work. http://www.laspilitas.com/garden/howto/slope.html

is EcoGrid used? EcoGrid can be used as either a temporary or
permanent ground reinforcement. It is used to reinforce lawns and
other grassy areas to prevent mud and damage to the ground. Once
laid ecogrid can be filled with stone, earth or seeded. When the
grass has grown EcoGrid becomes invisible but still resists wear
and compression. Ecogrid is perfectly suited to pathways, parking
lots or driveways and has numerous sporting applications such as
equestrian facilities and golf courses. EcoGrid is provides
excellent ground support and prevention from erosion.
