How Long Before Removing Concrete Formwork?

Concrete formwork is an essential part of a construction project when building walls, columns, beams, or slabs. The formwork is responsible for holding the concrete in place while it cures and dries to its complete strength. It is critical to know when to remove the formwork to avoid compromising the structural integrity of the concrete. So, how long before removing concrete formwork system? Let's take a closer look.


When can formwork be removed?


The standard practice is to wait a minimum of 24 hours before removing the formwork for structural walls and columns. However, the total curing time of a particular concrete structure will depend on several factors such as the ambient temperature, humidity, and the strength of the concrete mix. For instance, if the concrete mix contains additives that hasten the curing process, the formwork can be removed earlier than the 24 hours.


It is essential to note that removing the formwork too early can lead to the concrete collapsing or cracking, which can cause significant structural problems. Conversely, leaving the formwork in place for too long can also lead to problems such as the surface of the concrete not drying evenly, resulting in a weak and brittle structure.

Factors that affect the determination of formwork removal time


Several factors determine when it is safe to remove the formwork, including concrete strength, weather conditions, and project specifications. Additionally, the conditions on the site may also come into play when deciding the formwork removal time.


  • Concrete strength: The strength of the concrete determines when it is safe to remove the formwork. The standard recommends a minimum 24 hours, but depending on the type of concrete mix, the structure's size and complexity, and curing conditions, the relevant stakeholders, could adjust the formwork removal time.

  • Weather conditions: The ambient temperature and humidity significantly affect the curing time of concrete. In high humidity or low-temperature conditions, you may need to leave the formwork in place for longer to ensure the surface of the structure dries evenly.

  • Project specifications: The specifications of the project dictate the formwork removal time. In some cases, the specifications may require that the formwork remains intact for a more extended period than the standard practice.


In conclusion, the question, "how long before removing concrete formwork?" depends on several factors, including concrete strength, weather conditions, and project specifications. The standard practice is to remove formwork for walls and columns 24 hours after pouring the concrete mix. However, the total curing time will depend on the conditions mentioned above. It is essential to take the time to determine the best practice for removing the formwork to ensure the structural integrity of the construction project.
