We generally recommend the traditional “sand set” installation method for all Nantucket Paver blocks. With this method, you have greater control over your base and easier replacement of blocks that may become damaged over time. We do not recommend using Bluestone dust or Quarry dust as a base for our products.
In tests conducted by an independent laboratory in accordance with ASTM standards, our products have consistently exceeded the performance measures shown below:
- ASTM C1194 Compressive Strength of Architectural Cast Stone: 6000psi
- ASTM C1195 Absorption of Architectural Cast Stone: Less than 5% absorption
