How NOT to Build a retaining wall. RED FLAGS, common mistakes, bad designs pt1

What happens here

Utilize another retaining wall block as a grinding tool to smooth out the nurls (small ridges) on the top surface of the installed base course blocks. These nurls, if left untouched, can cause inaccuracies when leveling subsequent courses. By grinding them down, a perfectly flat surface is created for the next layer of blocks, ensuring a stable and even build. This technique ensures each course is as flawless as possible before laying the next.

Goal: Prepare the top surface of the base course blocks for subsequent layers.
