Using reclaimed stone on a dry stone wall can have both advantages and disadvantages, so it depends on the specific circumstances and goals of the project.
Aesthetics: Reclaimed stone can have a unique and rustic look that can add character and charm to the wall.
Sustainability: Reusing existing stone can be a more environmentally-friendly option than using new materials.
Cost: Depending on availability and the specific situation, reclaimed stone may be less expensive than purchasing new stone.
Inconsistent quality: Reclaimed stone can vary in size, shape, and quality, which can make it more difficult to create a structurally sound wall.
Availability: Finding enough reclaimed stone of the desired quality and size may be difficult or time-consuming, which can delay the project.
Unforeseen issues: Because reclaimed stone may have been previously used in another context, it may have hidden flaws or weaknesses that are not immediately apparent.
Ultimately, it is important to consider all factors when deciding whether to use reclaimed stone on a dry stone wall, including the quality and availability of the materials, the overall design and aesthetic goals of the project, and the budget and timeline. It may be helpful to consult with a professional dry stone waller to determine the best approach for the specific project.
