Myth #7

Resilience

"Any visible crack in reinforced concrete pipe means the reinforcing steel will corrode."

Fact: Within acceptable limits, cracking can indicate tensile load transfer to reinforcing steel and does not alone indicate corrosion or structural failure. Concrete protects embedded steel, and corrosion requires moisture, chlorides, and oxygen. In buried precast pipe, these conditions are limited, and small cracks may self-seal.

Measuring Sustainability Across the Full Life Cycle

Sustainability is measured across the full life cycle of an asset, not solely during manufacturing or installation. Life Cycle Assessment (LCA) examines environmental impacts from cradle-to-cradle, accounting for each stage of a product’s life cycle, including material sourcing, production, transportation, construction, operation, maintenance, and end-of-life management. This holistic approach provides a more complete assessment of environmental performance and long-term sustainability.
