Paving Grade Technical Specs

Performance Characteristics

• Permanent Color: The pigment is locked into the cement matrix and won't wash off.
• Weatherproof: 100% UV resistance prevents fading in direct sunlight.
• Efflorescence Neutral: Low salt content helps reduce the formation of white surface stains.
• Rapid Integration: Mixes quickly in high-speed planetary or twin-shaft mixers.

• Q: Why is my paving stone color inconsistent?

  A: This is often due to water-to-cement ratio variations. Our pigments are highly stable, but consistency in the mix is key for the best result.

• Q: Will the color fade under salt during winter?

  A: No, iron oxides are highly resistant to de-icing salts and chemical cleaners.

Landscape Design Services

We offer "Blend Development," creating custom multi-tone "Appalachian" or "Tuscan" color blends to give your pavers a natural, variegated look.

Mix Optimization: We can analyze your local sand and cement to provide a customized dosage guide for achieving your target "Stone Look."

The Science of Surface Saturation

In paving stone production, we focus on the "Paste-to-Aggregate ratio." To achieve a vibrant color, the pigment must fully saturate the cement paste that coats the aggregate. We optimize our pigment's "Water Demand" to ensure it doesn't dry out the mix, which can lead to poor surface finishes or "honeycombing." By controlling the particle size distribution, we ensure the pigment fills the micro-voids in the concrete surface, resulting in a denser, more colorful, and more water-resistant paver.
