Limestone for Retaining Walls: Avoid Costly Mistakes When Ordering Arkansas Stone

A retaining wall is only as good as the stone holding it up. When buyers order limestone for retaining walls without thinking through grade, size, and quantity first, the mistakes show up later: short loads that stall a job mid-build, stone too round to stack, or a delivery nobody can work with. Most of those problems trace back to the order, not the stone.

This guide covers how to choose the right Arkansas limestone for a retaining wall, how to size an order so the mason is not waiting on a second load, and what to ask the yard before the truck rolls. Rockhouse Stone Company stocks and delivers the stone. The wall itself is built by your mason or hardscape crew, so the goal here is getting the right material to the site, ready to stack.

Why limestone works for retaining walls

Limestone is a sedimentary stone made mostly of calcium carbonate, and Arkansas has deep deposits of it across the northern and central parts of the state. For a wall that holds back soil, what the stone does under load matters more than how it looks.

Density comes first. Arkansas limestone runs roughly 140 to 170 pounds per cubic foot, and that mass is what resists the lateral pressure a slope puts on a wall. Limestone also splits and saws along clean, flat planes, so a stacking wall gets the level top and bottom surfaces it needs to sit tight course over course. And it lasts. Limestone holds its edges for decades outdoors, so a wall built today reads the same in twenty years instead of rounding off and shifting.

If you are still deciding between stone types for the project, our guide on how to choose stone for a retaining wall (/blog/how-to-choose-stone-for-a-retaining-wall) compares limestone against fieldstone and other options. This post assumes limestone is the call and focuses on ordering it correctly.

The four limestone grades buyers ask for

"Limestone" covers several distinct products at the yard, and they are not interchangeable for wall work. Knowing the right name keeps the wrong stone off the truck.

Chopped or wall stone

Chopped limestone is split into rough rectangular blocks with flat top and bottom faces. It is the workhorse for stacked dry-laid retaining walls: the flat beds stack cleanly, and the broken faces give the wall a natural, textured front. Most residential limestone walls in Arkansas are built from chopped stone.

Dimensional cut stone

Sawn to consistent dimensions, cut stone produces a more formal, uniform wall with tight joints. It costs more per ton because of the extra processing, and it suits architectural or front-entry walls where a precise look is the point.

Cap stone

Cap stone is wider, flatter limestone for the top course of a wall. It sheds water, protects the courses below, and gives the wall a clean edge. Order it as a separate line item, because a wall body order rarely includes enough flat top pieces on its own.

Limestone boulders

For larger grade changes or a rugged, natural look, limestone boulders build a boulder retaining wall that doubles as a yard feature. These move with equipment, not by hand, so the crew and the site access matter. Tell the yard early if boulders are in the plan, because they load and ship differently than chopped stone.

How to size your limestone order

Short-ordering is the most common and most expensive mistake. A wall that runs out halfway through means a second delivery, a second minimum, and a crew standing around. Over-ordering ties up money in stone you may never use. Getting the quantity close on the first order is the whole game.

The rough math for a stacked limestone wall starts with the wall face area:

• Measure the wall face first. Length times height, in feet, gives you the square footage of the visible face.
• Then account for thickness. A dry-stacked limestone wall is usually 12 to 24 inches deep front to back, and deeper walls hold more soil but eat more stone per face foot.
• Convert to tonnage. One ton of chopped limestone covers roughly 25 to 40 square feet of wall face at a standard thickness. A 30-foot wall at 3 feet high has about 90 face feet, which lands near 3 to 4 tons.
• Add a waste allowance on top. Stacking always means trimming and rejecting pieces, so tack on 10 to 15 percent and the mason finishes the wall without a gap.

Picture a common job: a 40-foot bed wall holding back a sloped backyard, 2 feet high. That is 80 face feet, so figure 2 to 3 tons of chopped limestone, then round up to 3 with the waste allowance. Order 2 tons and the mason runs out on the last few feet of the top course, which is the exact gap that triggers a second delivery.

These are planning figures, not a substitute for the yard running numbers against the specific stone in stock. Coverage shifts with the size and irregularity of the pieces, so a quick call with your measurements in hand beats guessing every time. Rockhouse works the tonnage with you before anything gets loaded.

Delivery, access, and what to plan for

Limestone is heavy, and a wall order is rarely a small one. Sort out a few things before delivery day so the stone lands where the work happens.

• Pick the drop location before the truck arrives. Stone dumped close to the wall line saves hours of moving it by wheelbarrow, so walk the site and choose the spot in advance.
• Check site access. Soft ground, a tight gate, or overhead lines all change what kind of truck can deliver and where it can dump.
• Consider pickup for smaller walls. Hauling from the Hot Springs Village yard saves the delivery charge, but bring a trailer rated for the load. Limestone is dense and the weight adds up fast.

Timing helps too. Spring and early summer are the busy stretch for wall projects in Central Arkansas, so popular limestone grades move fast and lead times stretch. Calling ahead with your tonnage lets the yard hold or stage the stone for your build date instead of leaving you waiting on stock.

Rockhouse Stone Company coordinates delivery across Garland County and Saline County, and pickup at the yard is always an option for buyers who want to haul their own.

Who actually builds the wall

Here is the line that trips up first-time buyers: Rockhouse Stone Company supplies the limestone. It does not build, install, or set the wall. A dry-stacked or mortared retaining wall over a certain height usually calls for proper footing, drainage behind the wall, and in many cases an engineered design, all of which is the work of a qualified mason or hardscape contractor.

If you already have a crew, Rockhouse can supply them directly through a verified pro account. That account unlocks contractor pricing on volume and trade credit with net terms, so a builder running several jobs is not floating material costs out of pocket. If you are a homeowner who still needs a builder, ask the yard about a Rockhouse Connect referral to a local stone crew. Getting the right stone is step one. Getting it built right is step two, and the two are handled by different hands.

Limestone for retaining walls: frequently asked questions

How much limestone do I need for a retaining wall?

Estimate the wall face in square feet (length times height), then figure roughly one ton of chopped limestone per 25 to 40 square feet of face, plus a 10 to 15 percent waste allowance. For an exact number, give the yard your measurements and the wall thickness and they will run the tonnage against the stone in stock.

What size limestone is best for a retaining wall?

Chopped or wall stone with flat top and bottom faces stacks the most reliably for dry-laid walls. For taller walls or a rugged, natural look, limestone boulders work but require equipment to set. Cap stone finishes the top course and is ordered separately.

Is limestone better than fieldstone for retaining walls?

Limestone's flat bedding faces make it easier to stack into a stable wall, while fieldstone gives a rounder, more rustic look that takes more skill to lay tight. The right choice depends on the look you want and your mason's preference. See our guide on choosing stone for a retaining wall for a full comparison.

Does Rockhouse install retaining walls?

No. Rockhouse Stone Company stocks and delivers limestone and other natural stone. The wall is built by your mason or hardscape crew. Rockhouse can supply your contractor directly or point you to a Rockhouse Connect referral if you need a builder.
