Abstract:

The geogrid wall appears to have stabilized the site. The sod placed behind the geogrid improved the appearance of the wall as well as retained the fines in the backfill. It is recommended, however, that provisions be made on future projects for watering the sod until it is well established, particularly if there is an absence of ground water or if the backfill is free-draining. Also, backfill material containing organics would be helpful to promote sod growth. After assessing the problems of erecting a near-vertical wall, and the feasibility of establishing vegetation on a wall face, the geogrid wall has been termed a "permitted alternative" for Oregon.
