Home Business Introduction > Sea Sand Business > Business Guide
Our company contributes greatly to national industrial development by providing the Seoul Metropolitan Area with quality aggregates since its entrance into the sea sand business in 1984.

We gather raw sand in permitted mine lots with a gathering ship (Youngjin 16) operable in 40m or deeper water depths, and we use the best tugboat (Wonjin) in Incheon Port, to produce and supply quality washed sand that fully meets the expectations of our customers.
