Paver Pete demonstrates how to properly install geogrid in a segmental retaining wall installation.
Level the backfill.
Install a geogrid.
It is recommended to follow the recommendations of an engineer.
Here are our engineer’s specifications in this situation:
- Grid on top of the first course of blocks, 8 inches from the base
- Grid length of 8 ½ feet, measured from the face of the block to the tale of the grid
Drive a spike or a sod staple in the geogrid to tension it properly.
Cover an opening
The convex curve of our wall created a wedge-shaped opening.
We solved this problem by adding another course of grid with 4 inches of aggregate.
A geogrid should always abut and never overlap.
It should also always be installed in a straight direction.
