Tobermore Secura Retaining Wall
Large-format concrete blocks for gravity retaining walls — a mortarless segmental system for landscaping and civil works. Declared per 1 m³ of concrete (a running metre of wall uses only a fraction of a cubic metre), so the per-m³ figure is not directly comparable with per-m² paving.

Service Life — the B4 Replacement Input
50 years · EPD reference service life
The declared unit is stated as a useful service life greater than 50 years, so 50 is the declaration's floor rather than its estimate.

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.
