Block, stone and timber retaining walls
The right material depends on the height, the load, the water and the look you want. Here's how they compare.
Walk around Morgantown and you'll see every kind of retaining wall: hand-laid stone in the older neighborhoods near downtown, blocky concrete walls along steep streets, new segmental block in subdivisions toward Cheat Lake, and plenty of graying railroad ties holding up backyards. Each has its place.
How do the materials compare?
| Material | Best for | Watch for |
|---|---|---|
| Segmental concrete block | Most yard, patio and driveway walls | Taller walls need geogrid and a design; needs stone backfill and a drain |
| Natural stone (dry-laid) | Garden walls, terraces, matching older stonework | Height is limited by stone size and skill of the mason |
| Mortared stone or veneer | A finished look along a street or entry | Needs weep holes; rigid, so it cracks if the ground moves |
| Poured concrete | Heavy loads near foundations, parking and roads | Usually engineered; needs forms and truck access |
| Timber | Low beds and short borders | Rots in wet ground; a short lifespan for a structural wall |
Block walls
Segmental block is popular because it's modular, comes in many colors and textures, and can be reinforced with geogrid for real height. It doesn't need a poured footing, but it does need a compacted stone base, which is where shortcuts tend to happen.
Stone walls
A dry-laid stone wall drains through its face and can flex slightly as the ground shifts, which is why old ones survive on these hills. Mortared stone looks cleaner but needs drainage behind it, or water will push it over.
Timber walls
Timber is the cheapest to put in, but in a wet climate with clay soil it doesn't last as a structural wall. If you're replacing a rotting tie wall, ask for a price on block or stone too, so you can compare over the long run.
The contractor sets the price after seeing the slope, the soil, how equipment can reach the spot and what the wall has to hold back. We don't quote prices, and any figure you hear over the phone before someone has walked the site is a rough guess at best.

Common questions
Which retaining wall material lasts longest?
Well-built concrete, block and stone walls generally outlast timber by a wide margin. How long any wall lasts depends mostly on its base and drainage.
Can you match an old stone wall?
Often. Ask the contractor whether they can source stone close in color and shape, and whether they do dry-laid or mortared work.
