Plastic sheeting is a thin, flexible material that can be easily laid over the concrete to create a waterproof barrier. It is an excellent option for smaller pours, as it is relatively inexpensive and easy to install.
#### Tarpaulins
Tarpaulins, on the other hand, are heavier-duty and provide a more robust waterproof barrier. They are often used for larger pours and can be weighted down with sandbags or other materials to prevent them from blowing away in the wind.
Maintaining a Stable Concrete Curing Process
In addition to protecting the concrete from rain, it is also essential to maintain a stable curing process. This can be achieved by controlling factors such as temperature and humidity.
–
#### Temperature
The ideal temperature for concrete curing is between 50°F and 70°F (10°C and 21°C). Temperatures outside of this range can slow down or speed up the curing process, affecting the final strength of the concrete.
#### Humidity
The ideal humidity for concrete curing is between 50% and 80%. High humidity can lead to a slower curing process, while low humidity can cause the concrete to dry too quickly, resulting in a weaker finish.
Main Considerations When Curring in Rain
When curing concrete in rain, there are several key considerations to keep in mind. The following list highlights some of the main factors to consider:
- Ensure that the concrete is properly protected from rain using plastic sheeting or tarpaulins.
