Sudden Rainfall during pouring Concrete at Construction Site can create issues for those trying to achieve high quality of concrete. As weather conditions can’t always be predicted or avoided, the whole process of pouring concrete in the rain should not be a matter of concern if addressed properly.
Here, we are sharing possible conditions that can occur, if proper precautions are not taken & How to avoid issues occurring due to rain, to achieve a good quality concrete.
Condition #1- If Concrete Is Protected From The Rain
Pouring Concrete during rainy season is quite a cumbersome task. If you are careful enough to protect concrete in rainy season then you are more likely to achieve an even quality surface. It happens because once the rain has stopped, the surface water on concrete evaporates effectively in the same manner as bleed water from original concrete mix evaporates before the concreting process is completed.
When concrete is protected from heavy rainfall then excess water can’t get accumulated on its surface. This helps in easy evaporation and drying of concrete water resulting in strong concrete surface with no damage at all.
Condition #2- If Concrete is Not Protected from the Rain
If Concrete is not protected from Heavy rainfall during pouring process then, it can have serious effect on quality, strength and its overall appearance. If water doesn’t get evaporated from the concrete surface during the pouring process, the moisture gets retained in the concrete reducing its strength, quality and durability.
Condition #3- If Rain Starts Just After a Concrete Pour
Just because the rain starts during or soon after a concrete pour doesn’t mean that your construction project is ruined. It all depends on Timing and Stage of curing process of concrete.
- If Rain starts when the concrete is fresh just about 2—4 hours after mixing, the surface should be protected from the rain.
- If the finishing process is completed, rainwater may not cause damage.
- If the concrete become stiffed and is ready for grooving and grinding, just after 4—8 hours of mixing, then damage by rainwater is longer an issue.
