The Timeless Beauty of Natural Stone Retaining Walls
For centuries, natural stone walls have been a hallmark of durability and elegance. From ancient Roman structures in Europe to Incan stonework in the Andes, these walls have stood the test of time—proving that when built properly, they are among the longest-lasting and most visually striking options for outdoor spaces.
In the Pittsburgh area, natural stone is a cost-effective and aesthetically rich alternative to segmented retaining walls. Depending on the type of stone used, they can often be more affordable while offering unmatched character and charm.
Choosing the Right Stone for Your Project
The cost of natural stone walls varies based on material selection, with options ranging from budget-friendly repurposed sandstone to high-end limestone veneer. Here’s a look at the order of value from most economical to premium choices in our region:
- Repurposed Sandstone Block (affordable and historically significant)
- Sandstone Boulders & Steppers (natural, rugged appeal)
- Ledge Stone, PA Mountain Stone & Field Stone (classic and versatile)
- Colonial Stone & Sandstone Veneer (refined and elegant)
- Limestone Veneer (premium durability and sophistication)
At Wichman Landscape Construction, we’ve even repurposed granite wall blocks from outside the Pittsburgh region to craft stunning retaining walls—showcasing our commitment to creativity and resourcefulness.
Natural stone retaining walls can fall under three headings
1. Naturally Occurring Stone Retaining Walls:
Constructed from Fieldstone, Sandstone, Pa. Mountain Stone (a quarried product, Colonial Stone (Flagstone). Stone is either dry stacked or mortared with Geogrid. Stone thickness can be 1” – 3”, 2” – 4”, 3” – 6” or sized at 2”, 4” or 6” in thickness. Nominal wall thickness is a foot and wall can either be capped with Sandstone, Flagstone or Bluestone.
2. Sandstone or Mountain Stone Boulder Retaining Walls
These are constructed from quarried stone and are commonly used for retaining walls of any height. Large stones are typically 3’ x 2’ x 1’ (L x W x H) and then smaller sized boulders are used as fill or as small standalone wall stone. Wall is dry stacked with a batter and Geogrid is applied as necessary to lock the wall into the back fill.
3. Repurposed Sandstone Retaining Walls:
These are constructed from stones that are altered (chiseled, hammered, split, rock faced, and feathered & wedged) to form tightly constructed walls with small gaps. In this case, the wall surface can appear very uniform. Walls can be dry stacked or mortared.
