Great customer service. Delivery was done in a timely and professional manner. Fill dirt was reasonably clean and worked extremely well for the intended purpose.

Had a great experience. Entire team communicated clearly throughout the entire process. Had 8 tons of crushed rock dropped off at our off-grid location in Washington State and the delivery was smooth and easy. Will definitely use this company again in the future.

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.
