Snowy Site Savvy: Pumping Concrete Right

Pumping concrete in cold weather is undoubtedly challenging, but with careful planning and implementing these tips, achieving successful and durable results is possible.

Fremont, CA: As winters chill sets, concrete pumping projects face unique challenges. The plummeting temperatures can lead to concrete freezing in the pump or pipeline, bringing work to a standstill. However, with the right techniques and precautions, it's possible to keep the concrete flowing smoothly, even in the coldest conditions.

Understanding the Risks

Concrete is a mixture that requires a specific temperature range to set and cure properly. In cold weather, the risk of the mix freezing before it sets is high, which can compromise the strength and solidity of the structure. The water in the concrete can expand upon freezing, leading to cracks and structural integrity issues.

Hot Water to the Rescue

Hot water in the concrete mix is one of the most effective strategies to prevent freezing. This keeps the concrete's temperature above freezing during delivery and the waiting period. Similarly, when priming the pump, slurry mixed with hot water can prevent it from freezing against the pipeline walls, avoiding blockages.
