Comparison of Permeability between General Sand and Porosity Sand
				
				
			 
			
			
				Porous Sand Characteristics
				
					
						
							- Appropriateness of permeability (permeability coefficient 10-mm/m)
 
							- Fast drainage with 50% or more porosity
 
						
					 
					
						
							- Have your own strength and maintain the resolution strength
 
							- It can be classified by particle and used for various purposes such as gap water permeable packaging and front packaging
