Quarry Operations & Material Supply

EMC owns and operates active quarry sites to support reclamation, marine fill and general construction activities. We produce and supply a wide range of rock materials including:

We also supply building sand, pebbles and aggregates on a wholesale basis. All material production is supported by our fleet of Komatsu HM400 dumper trucks and heavy-duty excavators (Komatsu PC500, CAT K350 and CAT 345), ensuring reliable supply to project sites.

End-to-End Project Delivery

By combining expertise in marine construction, drilling and blasting, and quarry operations, EMC delivers projects using its own equipment, personnel and supply chain. This integrated approach allows us to maintain cost efficiency, schedule control and consistent quality across all stages—from rock extraction to coastal construction.
