What to Do If It Rains While Pouring Concrete

When pouring concrete, unexpected weather conditions can greatly impact the outcome of your project. One of the most concerning weather events is rain, as it can compromise the integrity and durability of the concrete. In this article, we will discuss the steps you can take to protect your concrete project if it starts raining during the pouring process. By being prepared and proactive, you can minimize the potential damage caused by rain and ensure the success of your concrete project.

Precautions to take before pouring concrete in rainy weather

Check the weather forecast

Before starting any concrete pouring project, it is crucial to check the weather forecast. If rain is expected, it is advisable to postpone the project if possible. However, if you cannot reschedule, make sure to take necessary precautions to protect the concrete from the rain.

Cover the area with tarps

One of the most effective ways to protect the concrete from rain is to cover the area with tarps. Make sure to secure the tarps properly to prevent any water from seeping through. This will help keep the concrete dry and avoid any potential damage.

Use additives in the concrete mix

Another precaution to take is to use additives in the concrete mix that can help accelerate the curing process. These additives can make the concrete more resistant to rain and prevent any water from affecting the final outcome. Make sure to follow the manufacturer’s instructions when adding these additives to the mix.

Steps to follow if it starts raining during the concrete pour

If you find yourself in the midst of a concrete pour and rain starts to fall, it’s important to act quickly to protect the integrity of the project. Follow these steps to minimize any potential damage:

Stop the pouring process

The first step when it starts raining during a concrete pour is to immediately stop the pouring process. This will prevent any additional water from getting mixed into the concrete, which can weaken the overall structure.

Protect the wet concrete

Once the pouring process has been halted, cover the wet concrete with a tarp or plastic sheeting to shield it from further rain. This will help to prevent excess water from seeping into the concrete and causing potential issues with the curing process.

Ensure proper curing after the rain stops

After the rain has stopped and the concrete has been protected, it’s crucial to ensure that the curing process is not compromised. Keep the concrete covered for an extended period of time to allow it to properly cure and achieve its maximum strength.

By following these steps, you can help to mitigate any potential damage caused by rain during a concrete pour and ensure a successful project completion.

Tips for repairing concrete that was poured in the rain

Assess the damage

If your concrete was poured in the rain, it is important to assess the extent of the damage. Look for any cracks, spalling, or discoloration that may have occurred due to the rain.

Allow proper drying time

After assessing the damage, it is crucial to allow the concrete to dry properly. This may take longer than usual due to the moisture from the rain. Make sure to give it sufficient time to dry before attempting any repairs.

Consider applying a sealant

To prevent further damage and protect the concrete from future rainfall, consider applying a sealant. A quality sealant can help to keep moisture out and prolong the life of your concrete. Be sure to follow the manufacturer’s instructions for application.


In conclusion, encountering rain while pouring concrete can be a frustrating and challenging situation for any construction project. However, by following the proper precautions and taking proactive steps such as covering the concrete, rescheduling the pour, or using additives, you can minimize the negative impact of rain on your concrete work. It is essential to always be prepared for unexpected weather conditions and have a plan in place to ensure the success of your concrete project. By staying informed and flexible, you can navigate through rainy weather and still achieve a high-quality concrete finish.
