Concrete and
masonry is a net
user of waste
107 times more waste & recovered
materials were used than were sent to
landfill
Concrete and
masonry is locally
and responsibly
sourced
89% is certified to BES 6001

Concrete and masonry is locally produced
Biodiversity
You might not associate concrete and masonry with biodiversity...but....
• MPA National Nature Park with 70 locations created by industry
• 5200ha of priority habitats created
• 6700ha in pipeline

Performance Benefits
To which aspect of sustainability does each performance benefit contribute?
Environ-mental
Social
Economic
Fire
Acoustics
Flood Resilience
Thermal Performance
Robustness
Durability
Fire Resistance
Concrete and masonry structures have excellent fire resistance, which means the ability to:
• Carry the loads on the structure
• Act as insulation against the heat from a fire
• Prevent fire spread through the structure

Environmental
• Reduced pollution from a fire
• Reduced waste of materials
Social
• Limits potential loss of livelihood or homes through fire
Economic
• Damage limitation – reduced costs to insurance industry
• 30% or more of businesses impacted by fire, go out of business
Sustainability through fire resistance
