Red Lava Rock
Lightweight 3/4–1 1/2" volcanic rock for beds and borders
Red lava rock is crushed volcanic stone full of tiny air pockets, which makes it light and easy to spread. It goes down like mulch but doesn't rot, break down, or need replacing every year. Use it in shrub beds, around cactus and succulents, and along borders where you want warm color with less upkeep. Pieces run about 3/4 to 1 1/2 inch. Size varies slightly and shade varies by location.
Red lava rock is lightweight, porous volcanic stone about 3/4 to 1 1/2 inch that spreads like mulch, not heavy river rock that's hard to move.
Also called: lava rock, red cinder, volcanic rock, scoria, cinder rock, red lava stone.

I initially ordered the wrong amount but the customer service representative, Jenel, helped me out by correcting it and giving me a refund immediately. I advised them where I would like the dirt to be dumped in my backyard and the driver made it happen. Great experience working with Jenel and Hello Gravel.

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
Use the calculator with your length, width, and depth. A 2 to 3 inch layer gives full coverage. One cubic yard covers about 105 square feet at 3 inches deep.
Lava rock weighs about a third as much as most gravel. Selling it by volume means you pay for coverage, not weight.
Mulch feeds the soil as it breaks down, and you refresh it every year or two. Lava rock doesn't break down, so you put it down once. Pick mulch for beds you dig often. Pick lava rock for shrub beds and borders you want to leave alone.
It's heavier than mulch and the rough edges grip each other, so it stays put in normal wind and rain. On steep slopes or right under downspouts, use edging to hold it in.
It's rough and porous, so wear gloves when you spread it. It's not a good fit for bare-foot areas, play areas, or dog runs.
By dump truck, straight to your property. The driver dumps it in one pile where you choose. Pick a firm, level spot the truck can reach, clear of cars and overhead wires. Delivery is included in the price you see.
