2 Tier Retaining Wall: A Comprehensive Guide
A 2 tier retaining wall is a type of landscape feature that provides multiple levels of support and visual appeal to a garden or yard. Also known as a tiered wall or stepped wall, it consists of two or more levels of walling, typically made of concrete, stone, or brick, that are designed to retain soil and create a visually appealing landscape.
