What is the maximum spacing for expansion joints in a concrete patio?

The maximum spacing for expansion joints in a concrete patio is typically recommended to be no more than 10 feet apart. This distance helps accommodate the natural thermal expansion and contraction of concrete due to temperature changes, which can cause cracking if not managed properly. Maintaining adequate spacing for expansion joints is crucial in preventing structural damage, ensuring longevity, and promoting the overall stability of the concrete surface. By limiting the distance between joints to 10 feet, it's easier to control stress, allowing the concrete to move freely without compromising its integrity. The selection of this spacing takes into account various factors, including the size of the slab and the expected range of temperature fluctuations, making it a well-established practice in landscaping and concrete work.
