LAVA ROCK
Reference onlyLava Rock (Volcanic)
Lava rock, a naturally occurring volcanic aggregate, is formed from rapidly cooled molten lava. Its unique volcanic origin gives it a lightweight, porous structure that sets it apart from traditional aggregates. The rough, irregular texture of volcanic lava rock enhances its ability to lock in place, making it a stable choice for a variety of landscaping and construction applications.
