Frequently Asked Questions

AI
For very low walls, a geogrid may not be necessary. However, if you are dealing with loose soil or a significant height increase, adding a stabilization grid prevents the wall from leaning or collapsing over time.
Concrete blocks are structural and designed to hold back heavy soil loads. Faux stone edging is primarily decorative and used for low-impact borders, mulch containment, and aesthetic landscaping.
Many segmental concrete blocks are designed for DIY installation. However, for walls over a certain height, consulting a structural engineer is advised to ensure proper drainage and safety.
