Hello Gravel Guarantee
Right material. Safe delivery. Real help if we miss.
How it works
- We fix what we control. Wrong material, confirmed fulfillment errors, or orders we cannot complete are reviewed for replacement, refund, or another fair resolution.
- Safe delivery comes first. The driver chooses the final safe dump location on site. If your requested spot is not safely reachable, we deliver to the closest safe location available.
- Plans change. You can cancel free up to one full business day before delivery. Next-business-day orders cannot be cancelled once confirmed.
- Natural material varies. Color, texture, moisture, dust, and sizing can vary by quarry, supplier, season, and region.

I work for an industrial construction company that deals with a lot of civil work, and I'm very accustomed to building a proper base with specific materials on projects we work on. The people at Hello Gravel were very pleasant to deal with. Prices are good. Unfortunately, the product I asked for wasn't available after paying for it, but they worked hard at ensuring I had a suitabe alternative. In the end, it all worked well, and the staff were very attentive. Lots of operators would not have gone through the trouble they did to make sure I was happy as a customer. Hello Gravel did

Frequently Asked Questions
Riprap is sized for erosion control, not coverage. Plan a 12-18 inch thick layer at minimum — heavier for high-flow water. The calculator above gives a baseline tonnage at 12 inches; for engineered installations, follow your project specs.
We deliver directly to your driveway or project site using a dump truck. Just choose your delivery date and time window (AM or PM) during checkout. Next-day delivery is available on orders placed before noon.
Yes! Delivery is included in the price you see — no hidden fees, no surprises. The price per ton (or yard) you see is the price you pay, delivered.
The minimum order is typically 1 ton (or 1 cubic yard for mulch and soil products). Our pricing gets better with larger quantities — a full truckload (18 tons) gives you the best per-unit price.
Due to the nature of bulk materials, we cannot accept returns once delivered. We recommend using our calculator to get the right amount — it's better to order slightly more than to run short mid-project.
Riprap is placed with equipment (skid steer, excavator, or by hand for small areas) on top of a non-woven geotextile filter fabric. The fabric prevents soil from washing up between the rocks.
Yes — a non-woven geotextile fabric under riprap is essential. Without it, soil migrates up between the rocks and the installation fails over time.
