Sand and Gravel Aggregate Industry Overview
Indonesia’s sand and gravel aggregate industry plays a crucial role in supporting the country’s booming construction and infrastructure sectors. Rich natural resources and increasing urban development drive steady demand for these essential materials.
Sources of Aggregates in Indonesia
Indonesia’s aggregates mainly come from two categories: natural sand and manufactured sand. Their distribution is significantly influenced by geographic conditions, resource availability, and policy directives. Below is a detailed classification and source analysis:
Natural Sand Sources
River Sand
Main Source
Key Distribution Areas
- Java Island: Rivers such as the Ciliwung River and Brantas River near Jakarta have historically been major suppliers of aggregates. However, resources have notably depleted in recent years, and government regulations on sand mining have tightened.
- Kalimantan: Middle to lower reaches of rivers like the Mahakam River and Barito River, especially in East and Central Kalimantan provinces, still hold relatively abundant resources. However, due to transportation and infrastructure challenges, development remains limited and resources require further consolidation.
- Sumatra: The Musi River basin is rich in river sand, serving as a major aggregate source for regions like Medan and Palembang.
Resource Characteristics
- Naturally rounded and smooth particles with relatively low clay content, suitable for medium to high-strength concrete;
- Long-term over-extraction has led to riverbed degradation and altered hydrological conditions, causing significant ecological impacts;
- Recent years have seen increased government restrictions to curb extraction and promote manufactured sand alternatives.
River Pebbles
Mainly composed of gravel transported and deposited by river currents, often found alongside river sand. In some areas, river pebbles are crushed to produce coarse aggregates.
Distribution
- Java Island: Along rivers like Ciliwung and Brantas;
- Sumatra: Lower to middle reaches of several rivers in the northern and central regions.
Resource Characteristics
- High strength and smooth surfaces, suitable for crushing into road base materials and concrete coarse aggregates;
- Distribution is limited by river transport capacity and alluvial fan ranges;
- Extraction policies are also tightening, encouraging transition toward manufactured crushed stone.
Quarry Sand (Mountain Sand)
Natural sand-like materials obtained by blasting, crushing, and screening rocks such as quartzite, granite, and andesite. In some regions, “quarry sand” refers to colluvial sand that has not been transported by water flow.
Key Distribution Areas
- Kalimantan: Mountainous areas in central and eastern parts, such as Kutai and around Samarinda, hold large resources but face high transportation costs; currently mainly supplying local infrastructure needs.
- Papua: Central highlands and western mountainous regions possess unexplored reserves with considerable development potential.
Resource Characteristics
- Angular particles with a higher proportion of flaky and elongated grains, requiring blending with rounded river sand or manufactured sand to improve concrete workability;
- Diverse mineral content including impurities such as clay and mica requiring processing;
- Although natural in origin and stronger than manufactured sand, quarry sand supply is less stable due to extraction efficiency and terrain limitations.
Manufactured Sand
Manufactured sand is artificial sand produced by mechanically crushing and screening rocks, tailings, or construction waste, typically with particle sizes below 4.75 mm. In recent years, manufactured sand has been widely promoted in Indonesia to substitute for increasingly restricted natural river sand resources due to environmental and policy pressures.
Raw Material Sources
- Tailings and Industrial Waste: By-products from mining processes such as nickel and tin tailings. For example, Sulawesi Island’s nickel mining generates large amounts of tailings annually, and companies like PT Vale Indonesia have started exploring tailings utilization to produce manufactured sand.
- Recycled Construction Waste: Includes discarded concrete, bricks, mortar, and other urban construction debris. Indonesia generates over 100 million tons of construction waste annually, with pilot projects for recycling construction waste into aggregates launched in cities like Jakarta, Surabaya, and Medan.
- Blasted Rock Materials: Mining and crushing of igneous rocks such as basalt, limestone, and andesite are currently the primary sources of manufactured sand.
Drivers for Adoption
- Resource and Policy Pressure: Natural river sand reserves are depleting rapidly; the government has tightened river sand mining permits (e.g., multiple regions in Java suspended new permits in 2023), pushing the market toward alternatives.
- Economic Advantages: After scaling, some manufactured sand operations achieve unit costs 10-20% lower than natural river sand, while offering more stable supply suitable for large infrastructure projects.
Types and Distribution of Crushable Rocks in Indonesia
Indonesia lies along the “Pacific Ring of Fire” and is characterized by complex geological structures and abundant rock resources. This provides a solid foundation for manufactured sand production. Crushable rocks used for manufactured sand mainly fall into three categories—igneous, sedimentary, and metamorphic rocks—each with distinct properties and applications.

| Basalt | Dense, high compressive strength (200–300 MPa), wear-resistant | - Mount Merapi, Java: 400+ Mt - Toba Caldera, Sumatra | Railway ballast, highways, flood control embankments | |
| Andesite | Uniform texture, moderate hardness (Mohs 5–6), easy to crush | - Jambi, Sumatra - Pangkalan Bun, East Kalimantan | Manufactured sand, concrete, roadbed—river sand substitute | |
| Sedimentary | Sandstone | Rounded particles, moderate cohesion, quartz-rich | - Riau, Sumatra: 200+ Mt - Pontianak, West Kalimantan | Building sand, coastal infrastructure, roadbeds |
| Limestone | High CaCO₃ content, chemically stable | - Bandung & Cikampek, Java: 1+ Bt - Jambi, Sumatra | Cement/lime production, road base, aggregate | |
| Shale | Fine-grained, low hardness, easily crushed | - Samarinda, East Kalimantan - Merauke, South Papua | Low-grade concrete, fill material, subgrades | |
| Metamorphic | Quartzite | Very hard (Mohs >7), abrasion-resistant, quartz-based | - Poso, Sulawesi: 300+ Mt - Wamena, Papua | High-durability flooring, high-speed rail ballast |
| Gneiss | Uniform structure, good mechanical properties | - Makassar, South Sulawesi - Malang, East Java | Aggregates for high-rise buildings and bridges, high-strength concrete | |
| Other Rocks | River Pebble | Naturally rounded, durable | - Ciliwung & Brantas Rivers, Java - Mahakam River, Kalimantan | Coarse concrete aggregate, filler |
| Tuff | Volcanic ash origin, loose structure, easily crushed | - Yogyakarta volcanic belt, Java - Lombok Island | Roadbed material, non-structural concrete, alternative sand source |
Indonesia’s manufactured sand industry is growing rapidly, supported by abundant and diverse rock resources. Among all regions, Java and Sulawesi stand out for their high-quality igneous and metamorphic rock reserves. As natural sand becomes increasingly scarce and environmental regulations tighten, manufactured sand (crushed by sand making machine) is expected to dominate the market. Tailoring crushing and screening processes to local rock characteristics—while adhering to green mining practices—will be key to sustainable industry development.

Industry Value Chain Distribution
Industry analysts typically categorize the aggregates industry in Indonesia into three major segments: upstream (resource exploration and mining rights), midstream (crushing, processing, and logistics), and downstream (concrete production, cement manufacturing, and infrastructure construction).
Upstream: Resource Exploration and Mining Rights Distribution
The upstream segment of Indonesia’s aggregates industry encompasses key elements such as resource types, geological distribution, mining rights acquisition, and the mining permit framework. It forms the fundamental layer that determines the sustainability of industry supply.
Upstream Value Characteristics
- Indonesia possesses diverse and geographically distributed aggregate resources. However, mining rights remain fragmented, and policy implementation varies across regions, resulting in suboptimal development efficiency and regulatory standardization.
- Ongoing reforms in mining rights and increasingly stringent environmental policies are expected to drive consolidation among small and medium-sized quarries, promoting large-scale, standardized mining zones.
- Securing high-quality mining rights, improving mechanization, and ensuring compliance capabilities will become core competitive barriers in the upstream segment.
Midstream: Aggregate Processing and Logistics
The midstream segment is the core value-creation stage of the aggregates value chain. It covers critical processes including primary crushing, manufactured sand production, screening and washing, and finished product transportation. Technical sophistication, equipment capability, and logistics efficiency at this stage directly affect product quality, unit cost, and market delivery capacity.
Midstream Value Characteristics
- The midstream stage is the key value creation point for “efficiency and quality” in the aggregates industry, with processing technology and equipment performance directly determining product grade and competitiveness.
- While traditional processes still dominate, this segment is undergoing rapid upgrading, driven by green infrastructure initiatives, the expansion of manufactured sand, and major projects such as the new capital city (Nusantara).
- The ability to establish and operate midstream processing facilities is critical for companies aiming to serve multi-regional markets and directly supply large-scale projects.
Downstream: End-Use Markets and Demand Structure
The downstream segment represents the end-use of aggregates and includes a wide range of sectors such as government infrastructure projects, urban real estate development, industrial park construction, and energy engineering. As Indonesia shifts its national development focus eastward (e.g., Nusantara capital project), accelerates industrial transformation, and experiences an expanding middle class, downstream demand is structurally upgrading.
Downstream Value Characteristics
- A threefold dynamic drives the Indonesia’s downstream market: national mega-projects, stable urban construction, and emerging growth in eastern regions.
- With the rollout of the new capital city and industrial parks, downstream demand is evolving toward localized sourcing, a higher proportion of manufactured sand, and increased requirements for green certifications.
- Companies that can establish stable procurement partnerships, ensure rapid supply responsiveness, and meet green certification standards will hold significant advantages in future competition.
Policy Overview
The regulation of Indonesia’s aggregates industry (covering non-metallic minerals and construction aggregates) is primarily governed by the Mineral and Coal Mining Law (Law No. 4/2009, amended by Law No. 3/2020) and its implementing regulations. It is also subject to environmental laws and land use policies. In 2021, Indonesia revised its mining law implementation rules through Government Regulation (PP) No. 96/2021, which replaced the previous PP 23/2010 and its amendments.
