Base Material and Compaction

What happens here

Gravel (Class 5 is recommended for good drainage and compaction) is added to the excavated trench to create a level and stable base for the retaining wall blocks. A plate compactor is then used to thoroughly compact this gravel layer. Compaction is crucial to prevent settling of the wall over time, which can lead to structural failure. The levelness of the compacted base is continuously checked to ensure the first course of blocks will be perfectly aligned.

Goal: A layer of compacted gravel is laid as the foundation for the retaining wall blocks, ensuring a stable and well-drained base.
