Frequently Asked Questions
1. How much does a load of top soil cost? That depends! When placing an order, be sure to clarify what you mean by "a load". We sell our materials by the cubic yard and a load can sometimes mean what your truck can carry (you will have to determine this by looking at your specific vehicle's payload capacity), or what our trucks can carry. We have two different truck sizes, so our small truck can carry 6 cubic yards of soil and our big trucks can carry between 15 to 30 cubic yards of soil depending on whether or not we have a trailer attached. That said, one cubic yard of soil varies in price from about $67 to $137 depending on the type of soil you choose. See our full price list in the PRICES link at the top of our site.
2. How much is a yard of topsoil? The cost of a cubic yard of topsoil varies depending on the specific blend you choose. Bulk top soil prices start at $67.66 and bagged soil (pick up only) is $13 per bag. Prices include the material only; delivery fees vary based on your location on Hawaiʻi Island. We deliver island-wide from Hawi to Hilo, with a minimum order of 1 cubic yard. For the most current pricing see our PRICES link at the top of the website or call us at (808) 326-9645. We also offer yard pickup if you prefer to have your own truck or trailer loaded. No appointment necessary during our business hours (Monday-Friday 7am-4pm, Saturday 8am-12pm).
3. How much does a yard of topsoil weigh? A cubic yard of topsoil weighs about 1500 pounds, sometimes more if we've had a lot of rain. If you're picking up from our yard in your truck or trailer, you also have the option to pick up half a cubic yard (around 750 lbs). It's important to consult your vehicle's manual to determine your payload capacity to avoid damage to your vehicle.
4. Do you deliver to my area on the Big Island? Yes! We deliver to almost every corner of Hawaiʻi Island. Our delivery area includes Kailua-Kona, Hilo, Waimea, Waikoloa, Captain Cook, Hōlualoa, Kohala, Puna, Keaau, Ocean View, and everywhere in between—from Hawi in the north to Naalehu in the south. We've been serving the entire Big Island since 1989, and our drivers know every road on the island. Delivery fees vary based on distance from our yard in Kona, and we have a minimum order of 1 cubic yard. For a delivery quote to your specific location, call us at (808) 326-9645 or use our online quote form. Keep in mind that there are some instances where our trucks may be unable to deliver, such as when it's necessary to cross a bridge that cannot support our truck's weight, or if your driveway is too steep or narrow. Please see our truck page at soilpluskona.com/trucks to view specific sizes and information about our trucks.
5. How much topsoil do I need? Calculating how much topsoil you need depends on the size of your project and the depth of soil required. Here's a simple guide: Basic Formula: Length (feet) × Width (feet) × Depth (feet) ÷ 27 = Cubic Yards Needed Quick Reference for Common Projects: Raised Garden Bed (4'×8'×1' deep): Approximately 1.2 cubic yards New Lawn (1,000 sq ft with 4" depth): Approximately 12 cubic yards Vegetable Garden (10'×10'×8" deep): Approximately 2.5 cubic yards Flower Bed (20'×3'×6" deep): Approximately 1 cubic yard Recommended Depths for Hawaiʻi Island: Vegetable Gardens: 8-12 inches for optimal root growth Lawns: 4-6 inches of quality topsoil blend Flower Beds: 6-8 inches Trees and Shrubs: 12-18 inches in the planting area Use Our Calculator: Visit our website and use our cubic yard calculator for a precise estimate. Just enter your project dimensions and it will calculate exactly how much material you need. Still Not Sure? Call us at (808) 326-9645! Our team has been helping Big Island residents calculate their material needs since 1989, and we're happy to walk you through it. It's always better to order a little extra than to run short in the middle of your project—and we deliver island-wide with a minimum order of just 1 cubic yard.
