About Drain Rock
Drain Rock is a drainage material sized at 1 - 2 inch with a density around 2700 lbs per cubic yard. The color runs gray. Larger, angular stone that maintains void space for water movement. Used in French drains, septic leach fields, foundation perimeters, and behind retaining walls. Wrapped in filter fabric for long-term performance.
Bulk orders are sold by the ton, with full-truck deliveries (16 or more tons) saving 15 to 20 percent off partial-load rates. Tandem-axle trucks haul 10 to 16 tons per load and fit residential streets; tri-axle trucks haul 16 to 24 tons and work better for contractor pours and commercial sites. We deliver same-day in most metros for orders placed before 11 AM, with a two-hour arrival window confirmed the evening before.
Pricing depends on quarry proximity, truckload size, the current diesel rate, and seasonal demand. The cheapest path is always a full truck dropped at a single address. If your project needs more than one load, splitting deliveries across two days costs less than two separate partial loads on the same day. Send your ZIP and dimensions through the contact form for a same-hour quote that includes the delivered total and the lead time on the lane.
After delivery, plan a few hours on the day of the drop to spread or stage the material. A wheelbarrow moves about 2 cubic feet at a time, which makes longer driveways or larger beds a multi-day job by hand. A skid-steer covers ten times that pace and rents for around $200 per day in most markets, often with same-day pickup. If you cannot start work right away, tarping the pile keeps the drain rock dry and intact for up to a week without losing weight or color.
What Drain Rock costs in Denver
Around Denver, drain rock is quoted by the ton with delivery layered in based on distance from the closest yard. Pricing in Denver starts at $59 per ton on full-truck loads, which works out to roughly $80 per cubic yard at the typical density of 2700 lb per yard. Plan on roughly 80 sq ft of coverage per ton at 3 inches deep, which puts a single-car driveway in the 4 to 8 ton bracket.
How crews use Drain Rock in Denver
Denver contractors keep drain rock on the order sheet for a short list of standard installs. Top of the list is drainage gravel, where the material is rolled out in tight urban lots and infill builds and screeded to grade. Right behind that is french drain gravel, common in dense neighborhoods where curb access is short and often paired with edging or fabric below the lift. Denver sits at about 713,252 residents, which means we see steady weekday traffic from landscape crews and weekend pickups from owner-builders.
Delivery day in Denver
Delivery in Denver runs out of the nearest pit; you get a two hour arrival window the evening prior and a call when the driver leaves the scale. Plan for 12 ft of clear path for a tandem and 14 ft for a tri-axle, plus a level area at the dump point so the bed lifts straight. Standard lead time on this lane is Mon-Sat, with same-day windows held open for orders that hit the desk before 11 AM and clear payment.

Does Drain Rock need filter fabric?
Yes. Wrap the Drain Rock in nonwoven filter fabric to keep fines out of the void space. This extends drainage life beyond 20 years.
How deep should the Drain Rock bed be?
4 inches below the perforated pipe and 4 to 6 inches above. Total trench depth depends on your local frost line.
What slope does a French drain in Denver need?
1 percent minimum (1 inch per 8 feet) so the water actually moves. Steeper is better.
How long does Drain Rock drainage last?
20+ years if wrapped in filter fabric and not buried under organic material.
Can Drain Rock be used around a septic field?
Yes. Most local codes specify a clean, washed stone like this for septic leach lines. Confirm with your CO code before installing.
