BUSINESS OPPORTUNITY
Accelerating infrastructure expansion across East Nusa Tenggara—including port expansion, industrial estate road development, municipal urban renewal, and cross-border road upgrades—drives massive demand for high-strength concrete paving blocks, heavy port-duty pavers, and precast drainage channels. Sourcing premium volcanic aggregates and silica sands from Timor quarries, this facility deploys heavy hydraulic multi-layer block-making machines with automated batching and steam curing. Locating inside KIB provides immediate captive demand for estate road paving, heavy logistics yard surfacing, and low-cost road transport access to municipal Kupang and Timor-Leste.
Revenue relies on B2B/B2G construction-project supply contracts (factory/warehouse construction at KIB, road, port, and housing projects), combined with regular sales to building-material store networks in Kupang and Rote Island.
BUSINESS OPPORTUNITY
Massive infrastructure spending across NTT—encompassing road rehabilitation, port upgrades, industrial estate surfacing, and municipal urban renewal—drives insatiable demand for certified high-strength concrete pavers and drainage precast. Currently, most local pavers are produced manually by informal roadside operators using weak mixes (below K-200), resulting in rapid crumbling under heavy truck traffic. An automated vibro-compaction plant in KIB delivers guaranteed K-400+ certified quality.
KIB’s ongoing infrastructure expansion requires tens of thousands of square meters of heavy-duty interlocking pavers for container yards and estate roads. KIB development plan · Reference not yet attached
Timor Island possesses exceptional basalt stone and river silica sand quarries yielding aggregate with high compressive crushing strength. Bolok Industrial Park Profile
Road reconstruction and urban development across the border generate strong demand for certified precast elements via the Trans-Timor corridor. Trans-Timor corridor · Reference not yet attached
Local supply is dominated by hundreds of small informal roadside yards using manual tampers and wet mixes that achieve compressive strengths below K-200. These blocks crack quickly under heavy truck axles. A fully automated vibro-compaction plant in KIB producing certified K-400 and K-500 pavers with automated batching wins large commercial and government tenders.
BUSINESS OPPORTUNITY
Raw aggregates and sand are sourced from licensed commercial quarries across Kupang Regency, supplemented by cement from regional terminals.
| Materials & Requirements | Procurement Source | Quality & Key Specifications |
|---|---|---|
| Crushed Basalt Stone Aggregate & River Silica Sand | Licensed commercial stone quarries in Kupang Regency and Timor rivers. | Clean, angular aggregate (0–5 mm stone dust and 5–10 mm chips), free of clay and organic matter. |
| Portland Composite Cement (PCC / OPC Type I) | Semen Kupang cement plant (local) / regional cement distribution terminals. | Fresh, dry bulk or bagged cement meeting Indonesian National Standards (SNI). |
| Specialized Concrete Chemical Admixtures & Pigments | Construction chemical manufacturers in Java, shipped via Tenau Port. | High-range water reducers (superplasticizers) and UV-stable synthetic iron-oxide pigments. |
Operating continuously year-round. Demand peaks during the dry season construction window (April–November).
Raw stone and sand are delivered via heavy dump trucks. Finished pallets are dispatched via flatbed crane trucks to construction sites across Timor.
Cement and aggregate represent 70%–75% of production cost. Automated electronic batching prevents cement overdosing while ensuring structural strength.
BUSINESS OPPORTUNITY
KIB provides the heavy industrial setting: high electrical power for hydraulic presses, expansive yard space for block curing, and central arterial road access.
BUSINESS OPPORTUNITY
Investors can deploy a semi-automated or fully automated multi-layer hydraulic block-making plant (500–1,000 m²/day capacity) paired with a twin-shaft concrete batching plant.
Automated block-making machine, twin-shaft batching plant, aggregate storage bins, cement silo, hydraulic curing racks, automated cubing/strapping line, and quality testing lab.
Delivering laboratory-certified K-400/K-500 heavy port pavers that eliminate premature surface failure captures lucrative institutional contracts for port aprons, industrial estates, and highways.
BUSINESS OPPORTUNITY
Bolok Industrial Park (KIB) prepares Phase I with a total area of 191 hectares under clean & clear Right of Management (HPL) land titles with flexible plot sizing, alongside ready-to-lease standard industrial warehouses. The facilities below represent the core estate infrastructure provided by KIB, while tenant-specific production machinery and specialized civil/utility works remain the investor's scope.
Heavy manufacturing land plots in KIB Zone I with extensive acreage for aggregate storage bays, batching towers, and palletized block curing aprons.
Prospective investors are advised to consult with the KIB management team regarding exact plot sizes, standard warehouse technical specifications, electrical power capacity, and water flow rates prior to concluding detailed feasibility studies.
The management team of PT Kawasan Industri Bolok (Perseroda) assists local, national, and international investors (Timor-Leste, Australia, China, etc.) from initial site inspection through to leasing and operational licensing.
