Typically, you can walk on concrete after 24 to 48 hours of setting. However, it takes around 28 days for each inch of slab thickness to fully strengthen. Optimal curing occurs at 85-90% relative humidity. It’s important to note that concrete’s exposure to elements can vary. For instance, concrete laid a year ago might have only been protected from the weather for the last month. Trust AR Concrete to guide you through the curing process for the best results.
The Difference Between Concrete Curing and Drying
Curing and drying are distinct yet crucial stages in the life of concrete. Curing begins immediately after pouring, primarily solidifying within 28 days but continuing to harden thereafter. This process is vital for strength and durability. On the other hand, drying refers to the evaporation of excess water, a longer process that can extend for months, depending on conditions like humidity and temperature. Quick tip: For optimal drying, maintain low relative humidity and a warm, consistent temperature, possibly by enclosing the area and utilizing HVAC. Remember, while concrete is ready for foot traffic within 48 hours, true strength and dryness are achieved only over time. With various concrete types and compositions, AR Concrete ensures each project is tailored for maximum longevity and performance, guiding you through every phase from curing to drying.
When is it safe to park on your freshly laid concrete driveway?
We recommend waiting a minimum of 14 days before parking personal vehicles on your newly poured concrete driveway. This duration allows the concrete to reach 90% of its full strength. However, for heavy vehicles like RVs, Trucks, heavy machinery, equipment, or buses, extend the wait to at least 28 days to prevent damage.
Parking or driving too soon can lead to cracks, tire tracks, or weakened concrete integrity. For walking, a 48-hour wait is sufficient, but avoid dragging feet or heavy activity for at least 4 days to prevent surface damage.
Note that these guidelines are specifically for concrete driveways; other materials may require different care. Always follow the specific guidance provided for your project to ensure the longevity and strength of your new concrete.”
