9 Ideal Natural Stones To Build A Privacy Wall In Your Yard

If durability is super important to you or you live in an area with extreme weather, granite is a great choice for your retaining wall. This tough igneous rock makes for super stable walls, especially if the structure is tall and needs to last for years. Granite’s ability to withstand harsh conditions is key to its long-lasting quality. And crushed granite makes an ideal base material because it packs down well while still allowing water drainage.

Flagstone is a mix of different natural stones, like sandstone, quartz, and feldspar, so you get some really cool color variations. It’s a relatively lightweight sedimentary rock that’s more resistant to damage from freezing and thawing than other types. Flagstone also has great longevity and its unique slabs add tons of visual interest.

Limestone is a super common natural stone that’s often used for retaining walls. It forms from compressed seashells, so you get a range of colors from white to brown, red, gray, and black. Limestone is great for walls in areas with big temperature swings because it resists cracking. You can use limestone blocks or bricks, or crushed limestone “screenings” to improve drainage and stability.

Bluestone is a unique type of limestone or sandstone that comes in shades of blue, brown, greenish, and even purple. Both the limestone and sandstone varieties are known for being super strong and durable. The sandstone type, found in the Northeast, has a cool layered texture. Bluestone is also affordable and holds up great against heat, moisture, and other elements.

Basalt is a dramatic-looking black or gray volcanic stone that’s perfect for building retaining walls. It’s super durable and can stand up to heat and acidic elements. Rustic basalt boulders make great dry-stacked walls with a modern, zen vibe.

Fieldstone is a natural rock that’s found right on the ground’s surface, not underground. It’s a great choice if you want your privacy wall to have a super natural, rugged look. The stones get a really cool, weathered texture from being outside. You can stack the slabs or bind them together tightly – just make sure to check the stones in person first to get a sense of how many you’ll need.

Sandstone is another super reliable retaining wall material – it’s been around for hundreds of years! You can keep the stones in their natural, diverse shapes or cut them into uniform blocks. Sandstone comes in a wide range of colors too, from beige to reddish purple. The porous structure allows some water drainage while still keeping soil in place. Just make sure you have a solid base to prevent shifting.

Slate is a tough metamorphic rock that’s super popular for dry stone retaining walls, where the stones are stacked without any mortar. Slate usually has cool layered texture from the quarrying process, but you can also find honed slate with a smoother finish. While it’s most commonly gray, you can find slate in gold, green, and marbled tones too. Just note that the layered structure means slate may need a different base material.

Quartzite, which is compressed sandstone, is an awesome choice for retaining walls – it’s even more durable than granite! Quartzite comes in a range of colors from sandy to reddish or bluish. You can use it to create a stunning gabion wall, where the stones are held together with wire. Gabion is a super sustainable privacy technique, plus it lets the natural beauty of the quartzite shine.
