Is Bank Run Gravel Good for a Driveway?

Good Underneath, Not on Top Bank run makes an excellent driveway base. The wide gradation means small particles wedge between the large ones under compaction, so the layer locks up and spreads load well. It costs roughly a third of what processed stone costs, which is why rural driveways and farm lanes are built on it. What it will not do is finish. Raw bank run has no wearing course, it tracks onto your shoes and tires, and it ruts under traffic. Cap it with 2 to 3 inches of crusher run or #57 once the base is compacted and crowned. How to Build It Spread in lifts and compact each one rather than dumping the full depth at once. On soft clay, lay geotextile fabric first so the stone does not punch down into the mud. Crown the surface slightly so water runs off instead of ponding.

What Is the Difference Between Bank Run and Crusher Run?

One Is Processed, One Is Not Crusher run is crushed to a controlled top size with the stone dust deliberately retained so the material binds. It packs into a hard surface that sheds rain, which is why it is the standard driveway wearing course. Bank run is dug out of a gravel bank or pit and sold essentially as-is. Nothing is crushed, nothing is washed, and nothing is graded to a spec. The blend is whatever the deposit holds, so it is looser, more variable, and considerably cheaper. Which to Buy Use crusher run for the surface. Use bank run underneath it, or anywhere bulk fill matters more than finish. On a driveway you often want both: bank run for the base, crusher run for the top 2 to 3 inches.

Does Bank Run Gravel Drain Well?

Partly, and Not Enough for a Drain Water does move through the coarse fraction of bank run, but the material commonly carries 10 percent or more sand and fines, and those fines slow flow considerably. Bank run drains far better than clay and far worse than clean stone. Never in a French Drain The fines will choke the trench, which is the exact failure a drain exists to prevent. Use clean, washed stone with no fines: #57 or #4. The same applies behind retaining walls and around foundation drains. There is a second reason to keep it out of wet locations. Where fines trap water in the section, a bank run layer can heave in freeze-thaw. Daylight the edge of the base wherever the site allows so water has somewhere to go.

Why Do Bank Run Gravel Prices Vary So Much?

Freight, Not Material Bank run has the widest gap between gate price and delivered price of any common aggregate. Published 2026 list prices put it near $8.50 per ton FOB at the quarry, while delivered pricing commonly runs $15 to $30 per ton. Consumer guides quoting $25 to $40 are usually reporting delivered prices in markets with a long haul. On a material this cheap, trucking is most of the bill. Delivery typically adds $50 to $150 per load within a normal radius, with per-mile charges beyond it. What That Means for You The pit's price per ton barely matters if you are far from it. Compare delivered quotes to your address, not gate prices. And confirm which product you are being quoted, since crushed bank run is a separate, higher-priced line item from plain bank run.

Bank Run Gravel vs Decomposed Granite: Size, Cost, and Which to Use

Bank Run Gravel runs about $7 per ton and Decomposed Granite about $43 per ton. Compare size, drainage, compaction, and which one to use.

Overview

Bank Run Gravel

Bank run gravel is pit-run aggregate dug straight from a gravel bank, pit, or river terrace and sold with almost no processing. It costs $7 to $16 per ton in 2026, weighs 1.4 to 1.65 tons per cubic yard, and is the cheapest truckload of anything most yards will sell you. What you get is whatever the deposit holds: sand, small gravel, stones up to several inches, and enough silt or clay fines to fill the gaps.

Decomposed Granite

Decomposed granite, or DG, is granite that weathered in the ground into a mix of sand, silt, and small chips, then was dug and screened to 1/4 or 3/8 inch minus. It costs $43 to $152 per ton in 2026, weighs 1.3 to 1.5 tons per cubic yard, and compacts into a firm, natural-looking path or patio surface in gold, tan, gray, or rose. It is the standard path material in California, Arizona, Texas, and most of the drought-tolerant West.

Pros & Cons

Bank Run Gravel

+ Cheapest bulk aggregate at $7 to $16 per ton
+ Wide gradation compacts and locks up well
+ Widely available anywhere there is a pit
+ Good structural fill under a wearing course

− Gradation and fines vary load to load
− Fines slow drainage, so it is wrong for drains
− Needs a capping layer for any traffic
− Can hold water and heave where it cannot drain

Decomposed Granite

+ Natural gold and tan look that fits Western landscapes
+ Compacts into a firm, walkable surface
+ $43 to $152 per ton loose, cheap where granite is local
+ Permeable, counts as pervious surface in many codes
+ Easy to install with a plate compactor

− Loose DG tracks into the house and erodes in rain
− Stabilizer adds $10 to $30 per ton
− Needs edging or it spreads
− Poor in freeze-thaw climates
− Muddy when saturated

Cost Comparison

Measure	Bank Run Gravel	Decomposed Granite
Per ton	$7 – $16	$43 – $152
Per cubic yard	$20 – $40	$84 – $109

Sizes & Colors

Bank Run Gravel

An unscreened blend running from sand and fines up through stones of 4 to 6 inches, with most of the material between 1/4 inch and 3 inches. There is no standard mix. The deposit sets the blend, so the pile at one pit looks nothing like the pile at the next one, and color follows the local geology from gray to brown to reddish tan.

Decomposed Granite

Decomposed granite is a mix of sand-sized particles and small granite chips, usually 1/4 inch minus, sometimes 3/8 inch minus. Colors run gold, tan, buff, gray, brown, and rose depending on the quarry. Gold and tan are the standard California and Arizona look. Sold loose, or stabilized with a binder that is mixed in dry or applied as a liquid.
