How to Build Seat walls & Columns for Landscaping, Ultimate DIY Guide for Backyard landscaping ideas

What happens here

Begin by establishing the precise layout for your retaining wall and columns. Use a string line to mark the outer perimeter, ensuring all corners form perfect 90-degree angles. Starting from a back corner, lay the first course of Belgard Tandem Wall base blocks directly onto a prepared and level compacted granular base. It is crucial to check the levelness of each block both front-to-back and side-to-side using a spirit level. Adjust any unevenness by carefully tapping the blocks with a rubber mallet, ensuring the entire first course is perfectly stable and level. This foundational step is critical for the overall stability and appearance of your entire wall system.

Goal: Establish a level and correctly angled base for the wall and columns
