Construction Aggregates
Construction aggregates are the raw, bulk materials—such as sand, gravel, crushed stone, and boulders—that form the literal foundation of modern infrastructure. Acting as the skeleton in concrete and the base for roads and foundations, they are the most mined materials globally by volume. In the Philippines, these materials are classified as "quarry resources," and their extraction is essential for building everything from residential homes to major public works like bridges and highways. Without a steady supply of quality aggregates, the physical development and economic growth of the nation would be impossible.
All Kinds of Sand and Aggregates
This category includes the sand, gravel, and crushed stone that are fundamental to all construction activities. They are the main components mixed with cement to create concrete for buildings, roads, and bridges. They are also used as base material for foundations and in the production of asphalt. Their accessibility and quality are vital for national infrastructure development.

Construction aggregates are raw materials like sand, gravel, and crushed rock used in construction. In the Philippines, these are generally classified as "quarry resources," and their regulation is often devolved to the Local Government Unit (LGU) where they are found, in coordination with the MGB.

Armor Rocks and Boulders
Armor rocks and boulders are large, durable quarried stones specifically chosen for their size, weight, and resistance to weathering. Their primary use is in civil engineering for erosion and shoreline protection. You will see them used to build breakwaters, seawalls, and revetments to defend coastal communities, ports, and infrastructure from the destructive force of waves.
