Quality & Manufacturing Process
High-grade materials, controlled hand-cast production, and independent laboratory testing — the process behind every CAPESTONE product.
Built on High-Grade Materials
CAPESTONE products are manufactured using high-grade raw materials, including selected aggregates, sand, and PPC cement, ensuring consistency, structural integrity, and long-term durability across all paving and tiling applications. Each product is hand-cast, allowing for controlled production and a natural stone-like finish, with inherent variation in colour and texture that reflects authentic material behaviour.
Through-Body Colour, Not a Surface Coating
Colour is achieved through the incorporation of premium imported iron oxides, fully blended into the concrete mix rather than applied as a surface layer. This ensures through-body colour consistency, improved wear resistance, and reduced surface degradation over time.
Controlled Production & Finishing
The manufacturing process follows standard concrete production principles, including batching, mixing, moulding, curing, and finishing, ensuring each unit achieves the required strength and durability performance. During production, strict process control is maintained to achieve uniform density and structural performance across batches.

Finishing
Ground, Polished, Revealed
For specialised finishes such as Nacre polished concrete, crushed abalone shell is incorporated into the mix. The surface then undergoes a mechanical grinding and polishing process using progressively finer abrasives, exposing the aggregate and shell inclusions while refining the surface to a dense, smooth finish. This process enhances both surface hardness and abrasion resistance, while revealing the material’s characteristic luminescence.
Performance Testing & Quality Assurance
CAPESTONE products are subject to ongoing quality control and independent testing through PPC Cement laboratories, ensuring compliance with industry performance standards. Concrete testing methodologies include evaluation of the following key properties:
Compressive Strength
Structural capacity
Durability & Permeability
Resistance to weathering and moisture ingress
Density & Consistency
Uniformity of mix
Abrasion & Wear Resistance
Performance in traffic areas
These tests are conducted using industry-standard procedures and equipment, providing verified performance data and ensuring suitability for both residential and commercial applications.
Verified Compressive Strength
7 Day and 28 Day Strength Tests refer to standard measurements of a concrete product’s compressive strength over time, expressed in megapascals (MPa).
Early-stage strength achieved within the first week after casting, showing how quickly the product gains structural capacity.
Full design strength reached after proper curing — the industry benchmark for long-term performance and load-bearing suitability.
In simple terms, these values confirm that the product continues to strengthen over time, reaching a high, reliable level of durability required for paving, structural, and architectural use.
Through the combination of quality raw materials, controlled manufacturing, and rigorous testing, CAPESTONE products deliver reliable, durable, and architecturally consistent solutions for a wide range of built environments.
