Lay the First Course of Blocks

What happens here

Lay the first course of interlocking concrete retaining wall blocks directly on the compacted gravel base. Ensure each block is level from front to back and side to side using a spirit level. Use a rubber mallet to gently tap blocks into place for minor adjustments. Continue laying blocks, ensuring tight seams and a consistent setback (if required by the block type) for each course. Periodically check the overall level and alignment of the course using a long level or string line.

Goal: Establish the level and stable base course of the retaining wall.
