Functionally, they hold back soils so you don’t end up with a backyard or driveway full of dirt. Decoratively, they serve to divide and/ or define a space.
In either case, it is nice to use products that hold up. 10 years goes by in a hurry, and you don’t want to have to replace a wall in such a short time. We use well-made precast materials from companies such as Versa-lok and Rochester Concrete, and solid, dry-laid natural stone.
Two different looks…both durable!
