Lava Rock Edmonton | Black & Red Medium Lava Rock

If you want a high-texture ground cover that acts like wood mulch but lasts forever, Medium Lava Rock is worth a look. Formed from cooling volcanic gas and molten rock, this material is famously lightweight, deeply porous, and genuinely unlike standard aggregate. We stock it in two distinct options at our West Edmonton yard: a sleek, deep Black Lava and a warm, burgundy Red Lava.

Because it’s a volcanic product, it has a real performance advantage over standard river stone. It absorbs and slowly releases moisture to keep your soil hydrated, yet it weighs a fraction of what traditional aggregates weigh — making it easy to wheelbarrow and shovel around your yard. Even better, it handles direct flames and intense heat without cracking, popping, or shattering, making it the top choice for outdoor gas fire tables and backyard fire pits across the Edmonton area.

A quick note on delivery and colour: like most of our decorative aggregates, lava rock is screened rather than washed at the source. It will arrive with a fine layer of volcanic dust coating the stones. Don’t sweat it — a quick spray with your garden hose or the first steady Edmonton rain will rinse the dust away to instantly bring out those rich, matte black and deep burgundy tones.

Whether you need a single 5 Gallon Bag to refresh a fire bowl or a few bulk yards to completely overhaul your front landscaping, we make pickup and delivery simple. Drive right in to load your own vehicle, or let us handle the heavy lifting with loose dump truck and Big Bag deliveries straight to your driveway anywhere in Edmonton, St. Albert, Sherwood Park, or Spruce Grove.
