Understand the Purpose of Polymeric Sand Compaction

What happens here

The video introduces the final and crucial step in paver installation for weed prevention, which is to vibrate polymeric sand into the joints. It explains that specialized heavy machinery, often referred to as 'roller compactors' or vibratory plate compactors, are used. These machines vibrate the surface of the pavers, which in turn causes the polymeric sand to settle deeply into the paver joints. The vibration effectively moves the sand that is initially lodged at the very top of the joint, down to the bottom, ensuring a complete fill.

Goal: Grasp the function of vibratory compaction for polymeric sand and its role in weed prevention.
