HADO LTD is a Kenyan mining company focused on Pumice excavation, processing and distribution.
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.
