Pouring concrete in cold weather
Concrete poured during cold weather needs to be protected from freezing and be able to develop the strength necessary for removal of forms.
Other considerations when pouring concrete in cold weather include ensuring proper curing conditions to prevent cracking.
The first thing to bear in mind is that you should never place concrete on frozen ground, which may result in uneven setting or cracking.
Use electric blankets or heaters to thaw the ground and be sure to get rid of any remaining water that could get into the mix.
Bear in mind, too, that you might need to rig up lights if the sun goes down before the concrete is ready for finishing.
Cold concrete pouring tips
These guidelines will help you to make sure that concrete poured in cold weather will achieve the required strength and avoid other issues while the concrete is setting.
• Before the cold concrete pour, ensure you have all materials, testing equipment and forms in place.
• Check cold weather protection measurements required for your mix.
• Keep a record of ambient temperature and concrete temperature.
• Be aware that special considerations and strength requirements may need to be met.
• Use insulation blankets to maintain concrete temperatures.
