Nadu Mining presents its jumbo raw perlite, the coarsest grade in our product line, developed for the most specialized and demanding applications. This product, sized within a narrow range of 1.2 – 2.4 mm (1200 – 2400 microns), consists of extra-coarse particles from which all finer material has been screened out. Its primary purpose is to produce expanded perlite aggregates of the largest possible size, with maximum porosity and mechanical durability.

This jumbo perlite fraction is engineered for niche applications that demand unparalleled drainage, aeration, and lightweighting capabilities. Its primary applications include:

• Advanced Hydroponics: Its expanded form creates an ideal growing medium for hydroponic systems, particularly for large plants like tomatoes and cucumbers in bato buckets. It guarantees maximum oxygen levels in the root zone and ensures the free drainage of water.
• Specialty Landscaping and Horticulture: It is used to amend heavy clay soils, preventing compaction and creating permanent aeration channels. It is also preferred as a drainage layer for highly water-sensitive plants and in bonsai cultivation.
• Ultra-Lightweight Concrete and Fills: When expanded, it becomes one of the best aggregates for ultra-lightweight concrete and fill applications where weight must be kept to an absolute minimum. It is especially suitable for landscaped roof gardens and floor fills where static load is a critical factor.
• Biofilter Systems: Thanks to the large interstitial void space created after expansion, it serves as an excellent substrate for carrier beds in wastewater treatment bioreactors or stormwater filtration systems, exhibiting high resistance to clogging.

Our 1.2 – 2.4 mm jumbo raw perlite is a specialized solution from Nadu Mining for professionals who seek performance beyond the standards and aim for maximum efficiency in their applications.
