Rivenstone™
The elegance and charm of Rivenstone lies in its Reala flagstone surface texture and the rich colors of the EnduraColor surface. Cast from molds derived from quarried flagstone, each piece has a unique clefted appearance. The choice of multiple sizes adds to the sophistication of your final design.
Base Requirement & Bedding Course – standard paver base specification or on open graded material for raised patios, terraces or concrete overlays. Do not use for vehicular applications.
Handling and Installation– This product cannot be compacted with a plate tamper. Use a hand mallet to make minor height adjustments. Care must be taken to avoid tossing stones so that they bang against each other. Damage to the surface appearance can happen if handled too rough. Both random and linear patterns are common. Install from multiple palettes for best color distribution. Install with ¼” spacing between units.
Jointing Material and Joint Stabilization
- Good: ordinary dry joint sand stabilized by a water-based or solvent based joint sand stabilizer (joint sand stabilizer sealer may make the surface slightly slippery).
- Better: Unicare Polymeric Sand, Techniseal RG+, Alliance Gator XP
- Best: EasyPro is best especially for open-graded base applications. Ensure that an approximate ¼’
joint is maintained during installation so that adequate jointing material can fill the voids.
Special Note: Alliance Gator Max Polymeric Sand (overlays). Make sure all proper Polymeric sand installation procedures are followed. See video at www.unilock.com.

Cleaners – Any cleaner can be used but Techniseal Hardscape Cleaner is commonly used.
