Yes, existing concrete or asphalt pathways can be converted into charming brick walkways through a process called “overlaying.” This involves laying bricks over the existing surface, provided it’s in good condition. The surface is thoroughly cleaned and prepared, and a layer of sand or mortar is applied to create a solid base for the new bricks. This method is more cost-effective and less time-consuming compared to completely removing the old pathway. However, it’s crucial to ensure that the base is stable and the overlay is properly executed to avoid issues like unevenness or premature deterioration. Consulting a professional is advisable to determine if overlaying is suitable for your specific situation.
