Nadu Mining presents the most specialized member of its product line, the 2.0 – 4.0 mm (2000 – 4000 microns) super jumbo raw perlite, for the most specific needs of advanced engineering projects. This product is derived from the precision screening of the coarsest available perlite ore and is designed exclusively for large-scale applications that demand maximum particle size. Its primary purpose is to create expanded aggregates that offer the ultimate in lightweight properties, the largest possible void volume, and the highest drainage capacity.

This super jumbo aggregate fraction was developed to solve unique engineering and geotechnical problems where standard solutions fall short. Its primary applications include:

• Geotechnical Lightweight Fill: In its expanded form, it serves as an ultra-lightweight geotechnical fill used to reduce lateral earth pressure behind retaining walls, support highway and bridge approach ramps over weak soils, or protect underground pipelines. It can reduce weight by up to 95% compared to traditional fill materials.
• Construction and Drainage Systems: It creates an ideal drainage and aeration layer for extensive green roof systems, ensuring rapid water removal while imposing minimal load on the structure. It is also used in drainage channels (French drains) around the foundations of large structures.
• Arboriculture and Urban Landscaping: Used to aerate the root zones of large trees planted in compacted urban soils and to prevent re-compaction. It provides permanent air and water channels, promoting healthy root development.
• High-Temperature Industries: When expanded, it serves as a loose-fill insulation material for large industrial furnaces and boilers or as an aggregate in specialty refractory concretes that require maximum insulation.

Our 2.0 – 4.0 mm super jumbo raw perlite is the most effective and innovative solution offered by Nadu Mining for the weight, pressure, and drainage challenges in your large-scale and technically demanding projects.
