Introduction to Sandstone Walls
Ever looked at a stunning stone wall and thought, “That’s exactly what my yard needs”? You’re not alone. Sandstone walls have a timeless beauty that works in both rustic and modern designs. But building them isn’t just stacking rocks—it’s an art form that starts with the right materials.
So, if you’re planning to install a sandstone wall, you’re in the right place. This guide will break down the 5 essential materials for installing sandstone walls and how to use them effectively.
Let’s dig in—pun intended!
Why Material Selection Matters
Building a sandstone wall is more than just a weekend DIY project. Choosing the right materials is the difference between a wall that lasts for decades… and one that crumbles after a year or two.
Durability and Longevity
The better the materials, the longer your wall will last. Think of it like cooking: fresh ingredients always make the best meals. Same rule applies here.
Aesthetic Appeal
Sandstone has that natural “wow” factor—but only if you match it with complementary materials. Get this combo right, and your wall will be the star of the landscape.
1. Sandstone Blocks or Slabs
The foundation (literally and figuratively) of any sandstone wall is—you guessed it—sandstone. But not all sandstone is created equal.
Choosing the Right Type of Sandstone
You can choose between rough-hewn boulders, cut slabs, or perfectly shaped blocks depending on the style you’re aiming for. Slabs give a cleaner look, while boulders scream “natural charm.”

Where to Buy High-Quality Sandstone

2. Crushed Gravel or Road Base
A strong base is key to any lasting wall. Without it, you’re building on a house of cards.
Purpose of a Solid Foundation
Crushed gravel or road base creates a level and compact surface that supports the wall and promotes drainage—critical for preventing shifting and cracking.
Installation Tips for Base Material
- Excavate 6–12 inches below grade
- Lay landscape fabric first
- Add 4–6 inches of gravel or road base
- Compact thoroughly (a plate compactor is your best friend)
3. Mortar or Construction Adhesive
Depending on your wall style, you’ll need something to hold it all together. That’s where mortar or adhesive comes into play.
Mortar Types and When to Use Them
- Type N Mortar: Best for above-ground walls
- Type S Mortar: Stronger; good for retaining walls
- Polyurethane Construction Adhesive: A great alternative for dry-stacked styles
Dry Stacking vs Mortared Joints
Dry stacking (no mortar) creates a natural look and works well with flat stones. Mortar provides more strength but requires skill.

4. Geotextile Fabric
This might sound fancy, but it’s a simple game-changer.
What It Does and Why You Need It
Geotextile fabric keeps soil from seeping into your gravel base and ruining drainage. Think of it like a filter—it lets water through but blocks the dirt.
Best Practices for Use
- Roll it out before adding gravel
- Overlap seams by at least 12 inches
- Anchor it down to prevent shifting
5. Drainage Pipes and Backfill Material
Moisture is the silent killer of sandstone walls. Proper drainage keeps water from building up behind the wall and causing pressure.
Preventing Water Damage
A perforated drainage pipe (a.k.a. “weeping tile”) at the base of the wall channels water away, keeping things dry and stable.
Ideal Backfill Choices
Use coarse gravel or crushed stone. Avoid clay or compacted soil that holds water.
