Tobermore Turfstone Grass Paver
Cellular concrete grass-reinforcement paver — an open-grid block whose voids are filled with grass or gravel to give a load-bearing, permeable green surface for overflow parking, fire paths and SuDS. Declared per 1 m³; the open cells mean less concrete and free-draining infiltration.

Turfstone concrete grass-reinforcement grid; declared per 1 m³ of concrete paving/kerbs/walling. At ~100 mm laid depth, 1 m³ ≈ 10 m² (≈34 kgCO2e/m²), and the open cells are grass-filled so actual concrete per m² is lower.

Comparison Status
The record contains the basic metadata required for a controlled comparison. Products must still perform the same function and use compatible units, PCRs and lifecycle scope.
Design & Specification Notes
Qualitative notes for early design discussion. Not product-specific EPD evidence, and not a basis for numerical comparison.
Cellular concrete grass-reinforcement paver — an open-grid block whose voids are filled with grass or gravel to give a load-bearing, permeable green surface for overflow parking, fire paths and SuDS.
Typical Uses
- •Paths & paving
- •Public realm surfaces
- •Permeable groundworks
Key Performance
Durable external surface with slip resistance.
Specification Actions
