Identify Signs of Eroded Polymeric Sand and Weed Growth

What happens here

The speaker visually demonstrates the consequences of unaddressed polymeric sand erosion. He points to areas where the sand has flaked out, creating cavities in the paver joints. He then pulls out a weed growing in one of these empty joints, explaining that these cavities collect airborne sediments like dust, dirt, and seeds, providing an ideal habitat for weeds to germinate and grow. He shows further examples of significant gaps between pavers filled with organic matter and emerging weeds, emphasizing the need for intervention.

Goal: Learn to identify eroded polymeric sand and subsequent weed growth in paver joints.
