Quick Answers

What thickness plywood for concrete forms?
18 mm (3/4") is the standard thickness for most US concrete forming applications. It handles slab, wall, footing, and column formwork at standard support spacing. Use 21 mm for heavy-duty or wide-span situations.
Can I use 1/2 inch plywood for concrete forms?
12 mm (roughly 1/2") plywood is only suitable for light-duty footings or curved formwork with very closely spaced backing support. It is not recommended for slab or wall forming.
Is thicker formwork plywood always better?
Not necessarily. Thicker panels cost more and are heavier. Match the thickness to your application, span between supports, and expected concrete pressure. Over-specifying adds cost without proportional benefit.
How do I calculate the right plywood thickness for formwork?
Consider pour height, pour rate, stud or joist spacing, and your target deflection limit. ACI 347 provides the design framework, and the APA publishes span rating tables for structural plywood panels.
