Tips for pouring concrete in hot weather
If your concrete pour falls on a hot summer day, don’t despair, our experts share their top tips for helping you install the perfect concrete pour even in the warm weather.
How does heat affect concrete?
Just like your laundry on a hot day, concrete dries, or cures, much quicker than usual in warmer weather. This is a problem because as part of the curing process, the concrete mix needs to hydrate (it needs to form crystals as it absorbs the water) in order to form the strength and durability the construction material is famous for. When the curing process is sped up however, the concrete struggles to form these all-important crystals which means it might not be as strong as you’d expect, resulting in cracks and weakness.
Avoid laying concrete between 11am and 3pm
Whenever you can, avoid laying concrete between the hottest part of the day, which is usually between 11am and 3pm. This way the concrete will be able to begin to cure in cooler temperatures and so form the bonds that make this construction material so renowned for its strength and durability.
Prepare the area before you begin
Before you begin your concrete pour, make sure the pour site is fully prepared and the surrounding area clear so you can install the concrete quickly and efficiently. It’s also a good idea to keep any tools you’ll be using cool by storing them in a shady spot.
Create shade over the concrete
Once the concrete has been laid, try to cover as much of it up as you can by creating shade. This can be very simple, such a hanging tarpaulin or a sheet over the concrete. If there is nowhere to hang the sheets, you may need to create them yourself by installing temporary poles.
Let the ready mix concrete professionals do it for you
Of course, the easiest way to ensure your concrete pour is successful is to call in the professionals. Opting for ready mixed concrete means you can get on with the pour directly from the truck, so the concrete spends less time exposed to the air.
