We’re back with Zara D'cotta from The Healthy Home to continue our chat about designing and building healthier homes.

This time, the conversation takes an unexpected turn, when Zara raises some concerns about low-carbon concrete. As a builder who’s used Holcim’s EcoPact mixes on site, he digs deeper to separate myth from material fact.

After Zara’s segment, you’ll hear directly from Holcim in response to the claims, bringing real world data and onsite context to the discussion.

In this episode:

• Picking up from Part 1: where health and sustainability intersect (and sometimes collide)
• Zara’s perspective on off-gassing, chemical content and embodied energy
• Dean’s practical take: what actually happens on site with low-carbon mixes
• Holcim’s response — performance, composition and environmental credentials
• Why facts matter when we talk about “healthy” and “sustainable” materials
• How builders can evaluate products without falling for fear or greenwash
