You can tell that some patios have not been built to allow for expansion by observing cracks or gaps in the surface. If the patio is rigidly attached to structures like walls or fences without any expansion joints, it is likely to experience stress during temperature changes. Additionally, if the patio is made of materials that are not flexible, such as concrete, and shows signs of buckling or uneven surfaces, it indicates that expansion considerations were not made during construction.
