How to Remove Shuttering from Concrete – A Simple Guide by Shuttering Board
Blog Article
When it comes to construction, the quality of shuttering directly impacts the finish and strength of the concrete structure. Knowing how to remove shuttering from concrete correctly is essential to ensure safety, structural integrity, and a flawless surface finish. At Shuttering Board, we not only supply premium formwork solutions but also help builders and contractors understand best practices for formwork operations.
What is Shuttering in Concrete Construction?
Shuttering, also known as formwork, is a temporary mold into which concrete is poured to shape structural elements such as slabs, beams, columns, and walls. Once the concrete sets and gains adequate strength, the shuttering is removed.
When Should You Remove Shuttering?
Timing is critical. Removing shuttering too early can lead to cracks or collapse. On the other hand, delaying removal increases project time and cost.
Here’s a general guideline:
Vertical supports (walls, columns): 16–24 hours
Slabs (bottom shuttering): 3–4 days
Beam soffits (props may stay): 7 days
Full removal of props: 14–21 days (depending on span and load)
Always refer to your structural engineer’s recommendations, and consider weather conditions and the type of concrete used.
Step-by-Step: How to Remove Shuttering from Concrete
Check Concrete Strength: Ensure the concrete has gained adequate strength (typically 70% of designed strength) before removal.
Start with Non-Load Bearing Sides: Remove side forms of beams and slabs first, as they don't support weight.
Use Proper Tools: Pry bars, hammers, or special formwork removal tools should be used carefully to avoid damaging the concrete surface.
Avoid Jerks or Impact: Gentle tapping is advised. Never use force that might crack or chip the surface.
Lower, Don’t Drop: If you’re working with heavy shuttering, ensure proper support and carefully lower each section.
Inspect Surface Immediately: Check for honeycombing or surface defects. Early detection means early repair.
