How to Choose the Right Stone for a Retaining Wall in Arkansas

A retaining wall is not a landscape feature. It is a structural wall that happens to look good. The stone you pick has to hold back a hillside, drain Arkansas rainfall, and survive 50 freeze-thaw cycles a year. Picking wrong means either rebuilding in five years or watching the wall lean before it gets there.

This guide covers the four main stone types used for retaining walls in Arkansas, what each one is good at, and how to match the stone to the wall you actually need.

Start With the Wall, Not the Stone

Before picking a stone, the wall itself has a few categories worth knowing.

Gravity walls are what most residential retaining walls are. They hold the hillside back by weight alone. The wider the base and the heavier the stone, the more load it can handle. Gravity walls top out around 4 feet tall in most residential applications without engineering.

Reinforced walls use geogrid or other internal reinforcement to handle taller loads. Anything over about 4 feet in Arkansas is usually reinforced, and walls over 4 feet typically require a permit and engineered drawings.

Dry-stack walls have no mortar. Gravity and friction hold them together. These drain freely, which is a huge advantage in Arkansas rainfall, and they move with the ground instead of cracking.

Mortared walls use stone and concrete together. They look cleaner but they do not drain as well and they do not flex. In Arkansas soil, mortared walls need weep holes and good back-drainage to avoid hydrostatic pressure from pushing them out.

Most of the time, dry-stack or lightly mortared natural stone is the right answer for Arkansas. The local climate rewards walls that drain and flex. It punishes walls that seal and resist.

The Four Main Stone Options

Fieldstone

Fieldstone is what most people picture when they think of a traditional stone retaining wall. Irregular pieces, natural shapes, earthy colors. In Arkansas it usually comes in tan, gold, gray, and brown tones with warm undertones.

Good for: - Traditional, natural-looking walls under 4 feet - Dry-stack construction where pieces fit together by shape - Properties where a rustic or country aesthetic fits the setting - Ground-contact applications, no concerns about weathering

Drawbacks: - Harder to stack than cut stone because every piece is different - Takes more time for a mason or DIYer working from scratch - Usually needs larger base stones for stability

Arkansas fieldstone typically ranges $150 to $300 per ton delivered, depending on size sort and distance from the yard.

Chopped Stone

Chopped stone is fieldstone that has been split with a chopper to give it one or more flat faces while leaving the natural color and texture on the exposed side. It stacks more predictably than irregular fieldstone but keeps the organic look.

Good for: - Walls where stacking speed matters without losing the natural look - Taller walls where consistent bed joints help with load distribution - Projects with tighter budgets than cut stone but want more than fieldstone - Mortared applications because the flat faces bed well

Drawbacks: - Costs 20 to 40 percent more than raw fieldstone - Less variation in face texture which some owners want

Chopped stone in Arkansas generally runs $250 to $400 per ton.

Flagstone

Flagstone is the thin, flat stone more commonly used for patios and walkways. It has limited use in retaining walls, but there is one place it fits well: capping a wall built of fieldstone or chopped stone. A flagstone cap finishes the wall cleanly and gives you a sittable top edge.

Good for: - Cap stones on top of a fieldstone or chopped stone wall - Low garden walls under 18 inches where structural load is minimal - Projects that need a crisp, flat top line

Drawbacks: - Not suitable as the body of a wall under load - Thinner stock breaks under compression

Arkansas flagstone runs $300 to $500 per ton for wall-cap grade.

Boulders

Boulders are the heaviest option. Individual stones ranging from 200 pounds to several tons. In Arkansas, sandstone and quartzite boulders from the Ouachita region are common. Limestone boulders are also available.

Good for: - Large-scale slope retention where a wall would be impractical - Waterfront and erosion-control applications - Naturalistic landscape features that hold back significant earth - Projects where heavy equipment is already on-site

Drawbacks: - Require equipment to place (mini excavator minimum, often larger) - Installation cost is high because of the equipment and labor - Aesthetic is specific and does not fit all properties

Arkansas boulders generally run $250 to $500 per ton, plus placement equipment costs.

Matching Stone to Wall Height

Wall height is the single biggest driver of which stone makes sense.

Under 2 feet — Almost any stone type works. Pick by aesthetic. Fieldstone for rustic, chopped stone for clean lines, flagstone for a low garden edge.

2 to 4 feet — Fieldstone and chopped stone are the two main choices. Chopped stone stacks faster for a mason. Fieldstone has more character.

4 to 6 feet — Chopped stone becomes the better answer because consistent bed joints matter more. Requires engineered drainage and a proper base. Probably requires a permit in most Arkansas jurisdictions.

Over 6 feet — Engineered wall territory. Boulders or large chopped stone with geogrid reinforcement. This is a professional job and the stone choice should come after the engineering.

Drainage Is Not Optional

The single biggest mistake on an Arkansas retaining wall is underdrainage. Arkansas gets roughly 50 to 55 inches of rain a year, most of it in spring storms. If water cannot get out from behind the wall, hydrostatic pressure will push the wall forward even if the stone is picked perfectly.

Every retaining wall, regardless of stone type, needs:

• Crushed stone backfill against the back face (3/4-inch washed or 57s)
• A perforated drain pipe at the base of the backfill tied to daylight or a drywell
• Filter fabric between the backfill and the native soil to prevent fines from migrating in
• Weep holes in mortared walls to let water out through the face

None of this is a stone question. It is a wall question. The stone gets blamed when drainage fails but the stone is rarely the cause.

Color and Regional Character

Arkansas stone has a specific regional palette. Sandstones from the Ouachita range run tan to gold. Limestones from across the state run gray to cream. Fieldstone from different parts of the state carries different undertones. Stone from north Arkansas can be grayer. Stone from central and south Arkansas tends to be warmer and more gold-toned.

For a wall that will sit in an Arkansas yard next to Arkansas plants and probably next to an Arkansas house, local stone almost always looks right. Imported stone from other regions can look transplanted. This is not about marketing. It is about how color reads in the specific light Arkansas gets, and how stone ages with the specific minerals in the water and soil here.

Frequently Asked Questions

How much stone does a retaining wall need per foot of length? A rough rule for a 2-foot-tall, 18-inch-deep dry-stack wall is about 0.4 to 0.5 tons per linear foot. For a 4-foot wall, figure 0.8 to 1.0 tons per linear foot. Chopped stone packs tighter than irregular fieldstone and may come in slightly higher.

Can I build a retaining wall taller than 4 feet without an engineer in Arkansas? Most Arkansas jurisdictions require engineered drawings and a permit for walls over 4 feet. Some require permits at lower heights. Check with the local building department before starting.

Do I need mortar in an Arkansas retaining wall? Not for walls under 4 feet. Dry-stack walls drain better, flex with ground movement, and are the traditional approach in Arkansas. Mortar becomes more common on taller walls, formal applications, or walls that will hold water features.

What is the difference between Arkansas fieldstone and chopped stone in price? Chopped stone typically runs 20 to 40 percent more than raw fieldstone because the chopping adds labor. For a wall, the extra cost often pays for itself in mason labor because chopped stone stacks faster.

Where can I see Arkansas retaining wall stone in person? Rockhouse Stone Company operates a 7-acre stone yard at 5643 HWY 7 N, Hot Springs, AR 71909.
