TerraSmart® Resin Bound Gravel System

Downloads

A raised, lightweight flooring system with a seamless resin bound gravel finish for roof terraces.

The TerraSmart® Resin Bound Gravel System combines the seamless appearance of resin bound flooring with a lightweight, adjustable raised structure. Its permeable surface makes it a strong choice for walkways and communal areas on roof terraces, while the aluminium Baseboard provides a solid foundation for the gravel finish.

Designed as part of a complete terrace scheme, the system can integrate with TerraSmart® Rail Paving Systems and Planter Systems. This gives designers the freedom to combine surfaces and landscape features while managing levels, drainage and the weight placed on the roof.

Roof terrace walkways

Create clear, continuous routes through a roof terrace with a permeable resin bound gravel finish. The boundary profile can form clean edges where the walkway meets paving, planting or another surface.

Communal outdoor spaces

For shared residential and commercial terraces, the system offers a jointless finish that can sit alongside seating, planters and other landscape features.
