What to Do If It Hails While Pouring Concrete

If you’re in the middle of a concrete pour and suddenly find yourself caught in a hailstorm, it can be a stressful situation. Hail can cause damage to freshly poured concrete and affect the overall quality of your project. In this article, we will discuss the steps you can take to mitigate the impact of hail on your concrete pour and ensure that your project stays on track.

Understanding the Impact of Hail on Concrete Pouring

When hail falls during the process of pouring concrete, it can have a significant impact on the outcome of the project. Hail can affect both the curing process of the concrete and cause potential damage to the final product.

How hail can affect the curing process of concrete

Hail can disrupt the curing process of concrete by cooling it too quickly. As concrete cures, it generates heat through a chemical reaction known as hydration. This heat is essential for the concrete to cure properly and achieve its desired strength. However, if hail falls on the freshly poured concrete, it can lower the temperature rapidly and interfere with the curing process. This can result in weaker concrete that is more prone to cracking and other structural issues.

Potential damage caused by hail during concrete pouring

In addition to affecting the curing process, hail can also cause physical damage to the concrete itself. The force of hailstones hitting the surface of the concrete can create indentations, cracks, and other imperfections. These imperfections can compromise the structural integrity of the concrete and lead to further issues down the line. Additionally, if hailstones are large enough, they can displace the concrete mixture, resulting in uneven surfaces and a lack of uniformity in the final product.

Overall, it is crucial to take precautions and protect the freshly poured concrete from hail to ensure a successful and durable outcome. From covering the concrete with tarps to rescheduling the pour on a day with better weather conditions, there are several strategies that can be implemented to mitigate the impact of hail on concrete pouring.

Immediate Steps to Take When Hail is Forecasted or Occurs

When hail is forecasted or occurs during a concrete pouring project, it is important to take immediate steps to protect the concrete from damage. Here are some key actions to consider:

Covering the concrete to protect it from hail damage

One of the first steps to take when hail is forecasted or occurs is to cover the concrete to protect it from damage. This can be done by using tarps or plastic sheeting to create a barrier between the hail and the freshly poured concrete. By covering the concrete, you can help prevent dents, cracks, or other forms of damage that hail can cause.

Monitoring the weather conditions and adjusting the concrete pouring schedule

It is also crucial to closely monitor the weather conditions and be prepared to adjust the concrete pouring schedule if necessary. If hail is imminent, it may be necessary to postpone the pouring process until the weather improves. By staying informed and flexible with the schedule, you can help minimize the risk of damage to the concrete.

Seeking professional advice if hail is imminent

If hail is forecasted or occurs during a concrete pouring project, it is advisable to seek professional advice from a contractor or concrete expert. They can provide guidance on the best course of action to protect the concrete and ensure the project stays on track. By consulting with experts, you can make informed decisions and take the necessary steps to mitigate any potential damage from hail.

Assessing and Addressing Damage After a Hailstorm

When a hailstorm occurs while pouring concrete, it can potentially cause damage to the surface. It is important to assess the extent of the damage and take necessary steps to address it promptly.

Inspecting the concrete surface for any visible damage

After a hailstorm, carefully inspect the concrete surface for any visible damage such as cracks, dents, or chipping. Pay close attention to areas where the hail may have hit with more force.

Repair options for hail-damaged concrete

Depending on the severity of the damage, there are several repair options available. For minor cracks or chips, you can use a concrete patching compound to fill in the damaged areas. For more severe damage, it may be necessary to hire a professional to repair or replace the affected sections of the concrete.

Preventive measures for future hail storms

To prevent future hail damage to concrete surfaces, consider installing a protective covering such as a carport or awning to shield the area from hail. Additionally, regularly inspect and maintain the concrete surface to address any minor damage before it escalates.

By following these steps, you can effectively assess and address damage caused by a hailstorm while pouring concrete, as well as take preventive measures to protect your concrete surfaces in the future.


In conclusion, dealing with hail while pouring concrete can be a challenging situation. However, by following the tips and guidelines outlined in this article, you can minimize the potential damage and ensure that your concrete project turns out successfully. Remember to prioritize safety, protect the concrete from further harm, and consult with a professional if needed. By being prepared and proactive, you can handle hail during a concrete pour with confidence.
