Important information for the Contractor or Finisher to know
Is the cold weather threatening to make your concrete project a disaster? PB Materials wants to defrost any problems that may arise, and keep you informed on what you need to know to have an outstanding, and problem-free concrete project.We would like to show you step by step on how to make your next concrete task simple.
Timing is everything
When pouring concrete, it is crucial to pour at the right time. A lot of time, you would think pouring concrete on a hot, sunny day would be best, when actually, the best weather is an overcast day with the air temperature around 55 degrees, lasting for 3-4 days. Unfortunately, life throws us curve balls— such as a sudden drop to freezing temperatures, which can make your concrete project seemingly impossible. Cold weather can freeze your concrete, rendering it a bad time to start a new concrete project. The great news is PB Materials makes any job paired with any weather conditions an easy go. Taking certain steps to make your concrete project durable and long lasting in cold weather conditions is effortless with PB Materials on your side.
How to correct the inevitable
Sometimes no matter what precautions we take, or even when following directions precisely, you still might run into a problem. But have no fear, PB Materials is here! When cold weather becomes a factor while pouring concrete, here are some simple solutions to make your project a success.
- Warm the desired area with insulated blankets. This will help you have a great start.
- Contact PB Materials and we will provide you with a chemical accelerator.
- Use heated water instead of cold.
- Boost the amount of cement slightly.
- Using all these steps will give you maximum results.
*Note: After pouring concrete, you MUST protect and cure concrete for 3-7 days with an insulated blanket, or plastic to let the concrete set properly, allowing the proper reaction to occur.
Applying a curing compound is a must for the hydration process. This allows concrete to establish its strength. This process is to ensure the outcome to be a success. It is very IMPORTANT that you do not allow the water that was added to your concrete to evaporate. As soon as you add water to your concrete, crystals begin to grow, allowing your cement to become firm. Without the proper hydration you will not receive the maximum strength, therefore receiving porous and weakened concrete. Adding an additive will help speed up the curing process, so when cold weather occurs, the additive won’t allow your hydration process to freeze. PB Materials has all the needed ingredients to make your cold weather concreting a solid hit.
When cold weather is a factor, your concrete can freeze during the curing process and may need repair or replacement.This term is called Spalling, which causes the water to freeze and expand, causing microscopic damage which interrupts the curing process.
This is what you need to do when you are in this predicament; The key to a successful repair is to cut around the damaged concrete until you have removed all weakened material. Next, moisten the area before adding concrete mix, then cover the damaged area with a Polymer Modified Cementitious Overlay. Once the overlay cures, applying a waterproof sealer to prevent the problem to reoccur. PB Materials is an expert on knowing how to battle cold weather when it comes to weather sensitive projects.
