Limestone Division

From Quarry to Infrastructure

At our Limestone Division in Scott’s Quarry, Verdant Vale, we employ advanced open-pit mining techniques to extract and process high-quality limestone aggregates. Our operations prioritize resource optimization, cost efficiency, and strict environmental compliance to support sustainable development.

Our Core Products

Crusher Run

Crusher Run is a blended aggregate consisting of crushed stone and stone dust, typically ranging in size from coarse particles to fines. This combination creates a well-compacting material ideal for use as a sub-base for roads.

Rip Rap

Rip Rap is a durable limestone rock aggregate available in various sizes, typically ranging from 4 inches to over 24 inches. Rip Rap's heavy, angular stones interlock to provide stability, making it ideal for retaining walls and drainage channels.

3/8" (10mm) Limestone

3/8" Limestone is a small, crushed limestone aggregate with a nominal size of 3/8 inch (10mm). It is commonly used in concrete mixes, driveways, landscaping, and as a base material for pathways.

3/4" (20mm) Limestone

3/4" Limestone is a medium-sized crushed limestone aggregate with a nominal size of 3/4 inch (20mm). It is ideal for use in concrete production, road bases, and drainage systems.

Mining & Processing

Limestone mining begins with site preparation, including vegetation removal and road construction for efficient material transportation. Geological surveys are conducted to assess the quality and volume of limestone deposits. Surface water management measures, such as stream diversion, drainage system implementation, and bench depressurization, prevent water intrusion. Sustainable resource management practices ensure that timber is salvaged per government regulations, and topsoil is stockpiled for land reclamation. Once the site is prepared, the drilling and blasting phase begins, where precision drilling creates strategic holes in the limestone, followed by controlled blasting to fracture the rock along natural discontinuities. Blasted Armour Rock is then transported by excavators and bulldozers for further processing.

The extracted limestone undergoes a dry crushing and screening process at our modern processing facility. Primary and secondary crushing stages break down Armour Rock into smaller fragments using crushers and interscreen units, followed by tertiary crushing and sieving for further refinement. These processes yield various saleable products that serve as the foundation for highways, access roads, and asphalt surfaces, playing a crucial role in national infrastructure development.
