Marshalls Concrete Block Paving

Name: Marshalls Concrete Block Paving
Brand: Marshalls

Pigmented concrete block paving for trafficked hard landscaping — driveways, car parks and public realm. Dense, colour-through or face-mix blocks laid on a bedding course. Module B1 shows CO₂ re-absorption (carbonation) over the service life. Representative of the Marshalls commercial block-paving range.

* EPD transport and installation scenario, not this project's. Module D shows potential impacts or benefits from reuse, recovery or recycling after the product's assessed life. It is reported separately and never added to A-C. Do not compare bar lengths between materials. Each chart may use a different scale and declared unit.

* A4/A5 are EPD scenarios, not project-specific results. Module D is outside the A–C system boundary and is not added to A–C. Module nomenclature follows BS EN 15978 / EN 15804. Declared values are suitable as inputs to a whole life carbon assessment under the RICS Professional Standard (2nd edition); this panel is not an assessment.

Upfront Carbon (A1–A5)*

14 kgCO₂e per 1 m² (138 kg)

A1–A3 11.8 + A4 1.24 + A5 0.922 · GWP-total, as declared

* Includes the EPD’s A4/A5 scenario assumptions, not project-specific transport or installation. This is the aggregation the proposed Part Z applies upfront limits to. The A1–A3 figure includes declared biogenic storage of -0.414 kgCO₂e; Part Z aggregates upfront carbon excluding sequestered carbon, which is the assessor's adjustment to make.

Service Life — the B4 Replacement Input

50 years · EPD reference service life

≈2 installations over a 60-year building study period.

B4 (replacement) follows the building, not the product: an assessor multiplies replacement cycles by project quantities. This record supplies the service life and does not compute B4.

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.

Pigmented concrete block paving for trafficked hard landscaping — driveways, car parks and public realm.

Typical Uses
