#67 Stone: Tight-Packing Crushed Stone in Bulk

The grade name describes a range more than a single size. #67 Stone tops out at 3/4 inch, and everything below that, down to pea-sized bits, stays in the mix after screening. Those smaller pieces tuck into the voids between the big ones. The result is a stone bed with less empty space and more contact between pieces, which is why it feels steady under a shoe. Expect a gray color, darker or lighter depending on the rock the quarry breaks.^[1]

A cubic yard weighs about 2,700 lb, and Gravel Valet sells #67 Stone by the ton. Every piece is crushed, so each one has flat faces and edges. When you run a compactor over a layer, those faces press flat against each other and the small chips wedge into the corners. Water still passes through, only a bit slower than it would through a grade with larger gaps.^[1]

Some yards call this grade by other local names, and a few sell a washed version with the dust removed. Ask for #67 Stone by number and the yard will know the gradation you mean. The fines that ride along in an unwashed load are not a flaw here, since they help the layer bind when you compact it.^[1]

Walkways and garden paths are a strong fit. People notice how a path feels before they notice how it looks, and a compacted layer of this grade gives a firm step without the rolling feel of round gravel. Wheelbarrows and garden carts roll across it with less effort as well.^[1]

Contractors like it under slabs, sheds and sidewalks. The packed stone spreads the load of the concrete across the soil and keeps a dry layer between the two. Plumbers and drain crews use it to bed pipe, since the mix of sizes cradles a pipe evenly along its length and leaves few hollow spots where it could sag.^[1]

Driveways and parking pads work too, especially where the owner wants a surface that holds a crisp edge. The gray stone also makes a neat base for a fire pit area, a hot tub pad or a play set, where a level, solid footing matters more than the look of the top.^[1]

Lay out the area with stakes and string, then dig out the grass and the loose top layer of soil. Tamp the floor of the dig before any stone goes in, since a soft subgrade will show through no matter how good the rock is. Edging made of steel, timber or paver blocks keeps the stone from creeping into the lawn over time.^[1]

For a garden path or a pad under a shed, a 2 inch layer of #67 Stone over firm ground will do. It takes about 0.83 tons per 100 square feet. For a sidewalk or slab bed, many builders go to 3 inches, which needs about 1.25 tons per 100 square feet.^[1]

Driveways and parking spots take more rock. Plan on a 4 inch layer at about 1.67 tons per 100 square feet, or 6 inches at about 2.50 tons per 100 square feet where trucks or soft ground are involved. Spread no more than a few inches at a time and compact each lift until a boot heel leaves no mark.^[1]

A light spray of water before compacting helps the small chips slide into place. Work from the edges toward the center, overlap each pass, and finish by raking a thin skim of loose stone across the top for traction.^[1]

#57 Crushed Stone is the grade buyers most weigh against this one. It is cleaner and more open, so it moves water faster and suits French drains better. #67 Stone wins where you want a surface that packs and feels solid. On a driveway either one can work, and the choice comes down to drainage versus a firmer ride.^[1]

#89 Crushed Stone is smaller still and fills paver joints and tight pipe bedding. 3/8" Crushed Stone makes a softer, finer surface for foot traffic. 3/4" Crushed Stone is a single-size grade close to the top of this mix but with fewer small pieces. #4 Crushed Stone belongs at the bottom of a heavy base, never on top where people walk.^[1]

Hard rock quarries produce this grade. Blasted bedrock goes through a jaw crusher, then cone crushers that break it into smaller pieces, and a set of vibrating screens sorts out everything 3/4 inch and below. Some yards wash it, some sell it as it falls off the screens, so a load may carry a trace of dust.^[1]

Gravel Valet works with nearby quarries and stone yards so the truck does not drive across a state to reach you. The rock in your load reflects the local geology, which explains why gray stone from one area may look a shade bluer or browner than the stone in another.^[1]

Small bags make sense for filling a pothole or topping a planter. For a path or a slab bed, the number of bags adds up fast, and so does the time spent loading, hauling and cutting them open. A bulk order by the ton puts the full amount on site in one visit.^[1]

Stone this dense, at about 2,700 lb per cubic yard, is expensive to move in small amounts. A dump truck spreads the trip over many tons. Buying the whole job at once also lets you compact the layers in one go, without stopping halfway while a second load is on its way.^[1]

Bulk stone also spares your back and your vehicle. A pickup bed loaded with crushed rock rides low and brakes poorly, and a trailer of it can overload a small hitch. One dump at the job site keeps the heavy lifting down to the shovel and the wheelbarrow.^[1]

Work out the square footage, choose the depth from the coverage figures, and the calculator shows the tons. Put your ZIP into the order box to confirm we deliver to the address, then add the stone to the cart and choose a delivery day that suits your schedule.^[1]

Plan the drop point with care. A loaded dump truck is heavy and needs a firm, level spot with open air above it. A driveway apron or a gravel pad is better than a lawn after rain. For a 3 inch walkway at about 1.25 tons per 100 square feet, a pile near one end of the path saves a lot of wheelbarrow trips.^[1]
