A concrete installation refreshes your property and gives your home a boost in curb appeal. After a concrete company has completed their work, protecting your new concrete is important for keeping it in top shape for as long as possible. When rain threatens it, it can affect your freshly poured ground. 

The Effects of Rain on Concrete

Rain & Concrete Surface

There are steps in the process where concrete is more vulnerable than others. While fresh concrete requires hydration for the curing process, too much rainwater on new concrete can cause trouble for the surface, particularly if it was just poured when the rain begins. Concrete may become too soft, reducing structural integrity and causing premature cracking.  

Timing is everything when it comes to rain and concrete. If the storm happens a couple of hours after mixing, your project should be fine. Also, if the finishing step is complete, the worksite should be safe as long nothing gets into the surface and slab. Stiffened concrete ready for grooving and grinding is also safe. This period is usually about four to eight hours after mixing.

How to Protect New Pours

For especially rainy areas, concrete companies will create a protective enclosure around the worksite. This enclosure is typically made from wood or plastic sheeting. If the storm hits beforehand, pushing water off the surface to the edge is effective in removing excess precipitation that can damage freshly poured concrete.

If rain disrupts the concrete company’s work, they will be able to test the surface for signs of damage after the storm has passed. They will inspect integrity and note any visible issues before performing repairs to freshly poured sections. Typically the same mix used to lay the initial pour will be utilized to make immediate repairs. For larger areas, contractors may choose to remove and replace whole sections.
