Lava rocks have many uses and benefits that people are starting to see:

Barbecue Lava Rocks

When lava rocks are used in barbecues, they reduce fat fires whilst enhancing the smoky flavour of a delicious barbecued meal. Just make sure that you replace clogged up rocks with a fresh new layer of lava as this will

  • improve the heat distribution
  • Improve the heat of the cook
  • Use less gas
  • Get rid of any nasty smells
  • Reduce flare-up

Chimineas and fire pits using Lava Rocks

Using lava rocks in a Chiminea insulates and protects. It is simple to do, just place a layer of rock into the potbelly of the chiminea and then build your fire on top. This protects the clay from direct heat and adds another layer of insulation to generate more heat from your chiminea. The rocks can also be used in a smoker, check out The Smoker Guy's website for more information.

Lava rocks are fantastic in fire pits. Functionally, fire pit lava rock provides a semi-permeable barrier that protects fire pit burner components from the elements, facilitates the even distribution of flame and the resulting heat, and shields the gas burner from direct exposure to the surface flame.  Cosmetically, lava rock is a clean, low-maintenance, durable, and natural-looking fire pit surface media that retains its natural colour under a combination of high-heat and potentially harsh weather conditions.

Lava Rocks for Mulch on the garden

In addition, they can also be used in the garden as mulch. The lava absorbs the heat during the day and releases it at night and is excellent for weed suppression. It also slows the evaporation of moisture from your soil. Lava Rocks are available in Ton bags by request, Please get in contact for a quote:

I asked for rocks, I got rocks. Came quickly and looks great (I actually wanted them for a tortoise enclosure)

Great to hear you are happy with the Lava Rocks!☺ We are intrigued to see how the lava rocks look in your tortoise enclosure, if you get the time we would love to see any images of your tortoise roaming amongst the Lava rocks! Kind regards, BRG team
