What if concrete gets rained on

Please note: Javascript needs to be enabled for this form to be used.. Posted on 18th June by Ever Readymix Concrete. When you want to pour concrete and find yourself up against the pouring rain instead, what should you do?

There are multiple reasons for pouring concrete in the rain, like being located in a consistently inclement climate, having a particularly wet winter or having to stick to a tight schedule. However, pouring concrete in the rain is different. Concrete can also be affected by cold temperatures , which is worth considering when pouring concrete during winter. Concrete can take 24 to 48 hours to set and around a week to partially cure.

During this time, walking on the surface is allowed. However, due to the nature of concrete consistency, it is best to avoid heavy equipment during this period. This will ensure no damage is caused to the surface. Typically, concrete can take 28 days to fully cure, however, it continues to cure indefinitely throughout its lifespan. I like to keep the slab moist for days in the hot summer. Even if it is just turning the sprinkler on a few times a day.

My husband decided to use mesh because it is more easily repairable. Neither of us have experience in this and he was advised this was a good option. It's a class C concrete, if that helps any. The cheapest thing you can do for a slab is add more appropriately placed rebar. While mesh may suffice for you, I would never, ever, solely use it. The thought of using mesh because it is easier to fix is not that sound Place concrete properly to never have to redo it. Other opinions may vary, but with cracks like that I would consider filling the construction joints with Sika flex.

In your freeze thaw climate you don't want water penetrating through the cracks. SGC, thanks for your helpful advice. Some of the cracks extend into the cut joints. Should we put that product in there, too?

My husband also said that since many of our neighbors' concrete driveways have rust stains that have shown up after a year or two he wanted to avoid the rebar under ours. We have fibers in our concrete, not sure if that's relevant at all. Yes, with cracks like that I would seal all cracks and construction joints. If there any more that are that size that you can fit a coin in, water is going to be an issue, or maybe not BUT you spend a pretty penny on that expansive driveway.

Risk vs Reward. Protect your investment. Just wanted to update everyone. We had an engineer come out and test the hardness of the driveway. It was psi after 21 days, said it would continue to harden. The cracks are fine, the control joints not going all the way to the edges were due to laziness on the part of the guy doing the cuts, he said. All seems to be ok. The man in charge of the pouring has not yet been out to look at it, however.

The Concrete that was poured in the did not crack or flake off. Was not poured in the rain. The rules are different today because of cheap and lazy. If water gets in the cracks and freezes over there will probably be problems. Yep, but it would be interesting if the OP would post pics of how the driveway has fared over the past three years! I layer a few bags of my cemete for the center of my garden. It always drizzles in Florida, and it did stop for a while poured at 4pm, finished in about an hour, the the drizzle came.

I went out at 8am and covered it but since this is a home project, I don't have access to anymore cement before buying more and I'm not sure it possible. I would post your own new post rather than piggy backing on an old post. Add pics when you start your new thread. I've never been on this site before and if somehow, I eessed up, I apologize. I google for those who know what they're.

This seemed perfect. And the above was very. The main reason for cracks is bc nine times out of ten when the contractor lets the concrete set up and start to dry and then goes again and adds water to it it causes the concrete to become weaker and weaker the more times it cures and then water is applied again.

Also it can happen when 2b is put down and not compacted before a pour the ground and 2b shifts with causes the concrete to crack. The 1 inch cut thats done in the concrete is so when or if the concrete should crack break bc of movement or weight it would break evenly and not cause a spider web break.

Its never really recommended to pour on a very hot day and if you can avoid it then avoid it bc its better on a cool day being the concrete will dry on its own anyways either in cold conditions or under water but will not avoid the cause of flaking or cracking by doing so. No one should ever add water if qhen the concrete sets up and if you push your finger down in it and see your print or feels dry.

But that's if the pour was done in the last 4 hours bc with in that time your able to fix it after 4 hours then no water or anything bc you can mees up the cycle if its curing process. But if it rains within the 4 and 8th hour its ok bc it will be hard enough so the rain water don't mess anything up. Now if you notice that the rain drops caused a problem and theirs standing water its ok to take a garden hose and pull the access water off and try to fix it but try not to cause more damage then it has bc remember you didn't want to mess the process up that has started or create more damage.

I think it would be nicer if the driveway could be moved over and the parking pad approached by going between the large tree and the tiny new tree in the last pic, and parked straightin, perpendicular to the fence. Would that be possible? Or at least come thru between the trees and have the car face in the opposite direction of what it is now.

That way, the car wil be away from the edge of the yard, and if you were to add a sidewalk or stone or even a dedicated pea gravel walkway with eging to hold it in place, your tenant would be a little closer to the house and you would be able to landscape the far corner, and then along the fence. You could curve the path a bit so that it swings out from the fence toward the road, and ends closer to the steps.

See how you would walk to the house from the car, and follow that line, but not in a straight line. Then, as it is a rental, try to plant some shrubs dwarf varieties will not grow out of control! The wind can also have a negative impact on the curing process.

Strong winds can cause bleeding in the concrete and affect the evaporation rate of its internal moisture. It is a well-known fact that rain can affect traffic on the road. This can create undesirable delays for the transportation and delivery of fresh concrete batches.

Suppliers need to keep an eye on the weather and avoid making deliveries during the rain. If this is not possible, then drivers should plan to use alternatives routes with less traffic. Any delays in the placement of concrete reduce the workability which ultimately causes a reduction in the initial strength of the concrete.

Delays in delivery will be costly to the project and will allow water to affect the construction site. Plastic sheets and waterproofing canvas should be kept on-site during the rainy season.

Once a concrete batch is poured, cover it with sheeting to shield the concrete from the rain. This will keep moisture in the concrete and keep excess water out. Waterproof covers can also be used to protect aggregates and keep them dry.

Using covers and traps will protect small slabs. A self-leveling compound can be applied later if necessary to smoothen the surface.

Tarps and covers can also be used for larger areas to good effect. This ensures no rainwater pools in trenches dug for footings, foundations, and slabs. This is important, as rainwater can bring with it contaminants. Once the rain has subsided, asses the concrete and see if there is any damage or pools of water on the surface. A simple scratch test can be done to see if the surface of the concrete has been affected by the rain. If there is any surface damage or dimples left by the rain on the concrete surface, contractors can use a float to remove excess pools of water and smooth the surface of the concrete at the same time.

The key to ensuring the success of a building during the rainy season is preparation. Be ready for heavy rains and have the right types of equipment and materials on hand to deal with the wind and water. Pouring concrete in the rain is not advisable, rather stop and wait for the rain to pass and clear the atmosphere then remove the surface water in the foundations or on the already-poured concrete before completing the pouring of concrete. Concrete should cure for at least 4 to 8 hours or it gains sufficient strength and becomes hard.

If concrete is still fresh during rain, it must be covered with plastic material in order to protect it from rain. No, Concrete pouring must be stoped during rain and fresh concrete must cover with plastic materials.
