Identify Missing Geogrid Reinforcement

What happens here

The presenter points out a critical flaw in the wall's construction: the absence of geogrid. Geogrid is a geosynthetic material specifically designed to reinforce the soil mass behind a retaining wall, thereby increasing its tensile strength and preventing the soil from pushing the wall outward. Its omission significantly reduces the structural integrity and stability of the wall, making it highly susceptible to failure, especially in taller walls or those under significant soil load.

Goal: Recognize the absence of geogrid as a major construction defect.
