Pure natural pumice light weight lava block brick 

Lava stone is a natural volcanic rock that is quarried, which contains many kinds of mineral materials, such as silicon,magnesium, nickel,etc.

 

Lava stone chemical composition:

 

SiO2	Al2O3	Fe2O3	CaO	Na2O	MgO	K2O	FeO	TiO2
53.82%	16.89%	9.08%	8.36%	2.55%	2.46%	2.3%	2.55%	0.06%

 

 

2. Advantages 

 

It typically conserves the soil, enhances soil ecology and stabilizes yield.

 

a. Organic. Lava rock is a form of igneous rock created by the eruption of volcanoes. It can be purchased at most home and garden stores in black or red. It is an organically produced mulch, since it comes from the earth. 

 

b. Keep water. Lava rocks can help keep water in the soil and they can keep weed growth down. As the lava rock breaks down into what's known as lava sand, the sand mixes into the soil and allows the soil to hold in more water. 

 

c. Make soil warmer. Because lava rock is dark-colored, it tends to make the soil underneath it a little warmer than it would be otherwise. 

 

d.Long-lasting. Lava rocks are a long-lasting mulch choice that will be especially attractive in perennial beds or around shrubs so that you don't have to move the rocks to plant every year.
