Introduce Geogrid and its Function

What happens here

Introduce geogrid, a special geotextile matting, as a crucial horizontal reinforcement for retaining walls. Unlike filter fabric, geogrid has open spaces that allow water and soil particles to pass through while still providing structural strength. This prevents the trapping of water and dirt, a common issue with vertical fabric installations that can lead to wall failure. The geogrid is installed horizontally behind the blocks to tie the wall into the earth.

Goal: Understand the purpose and proper placement of geogrid in retaining walls.
