Misconception of Placing Plastic Under Concrete

This chapter debunks the notion that placing plastic underneath concrete prevents even drying and causes curling, explaining that moisture still moves through concrete despite the plastic. It discusses the use of plastic sheets in structural engineering to mitigate shrinkage cracks and minimize strain and shrinkage. Additionally, it explores the responsibility of specifying a structural slab and the importance of collaborating with subcontractors in design build projects.
