Detailed Leveling and Gravel Backfill

Chapter 1-the Start of a new wall
What happens here
Once the first course of blocks is laid, the focus shifts to meticulous leveling and back-filling. Each individual block is checked and adjusted to ensure it is perfectly level both horizontally (side-to-side) and vertically (front-to-back, matching the desired slight slope away from the retained soil). The blocks are also leveled relative to their adjacent counterparts to ensure a smooth, continuous surface. After leveling, the space directly behind the first course of blocks is filled with additional gravel, which is then compacted to provide essential drainage and further stabilize the base. A mini excavator is used to efficiently move and distribute the backfill material.
Goal: Ensure perfect block alignment and structural integrity of the first course with proper backfilling.
