OUR PRODUCT

After excavation and processing, our resultant product comes sifted in three different particle sizes of rocks.
We grade them into three categories;

• Small Pumice rocks- 1/8" Aggregate/3mm.
• Medium Pumice rocks- 1/2" Aggregate/7mm.
• Large Pumice rocks- 3/4" Aggregate/14mm.

In addition to the rock aggregates, we also offer;
- Pumice powder grinded on site from the rocks.
- Pumice blocks made on site on request.
We combine pumice with trace amounts of cement to create very light weight durable building blocks.

• Is siliceous and very inert in nature.
• Insoluble in water.
