String Line

A string line, or mason’s line, is a strong, thin cord used in masonry and landscaping to create straight lines between two points. It is typically stretched between stakes or posts to guide the placement of bricks, pavers, or stones, ensuring that the rows remain straight and level. String lines are crucial for achieving precision and uniformity in laying out patios, walkways, and walls. The cord is usually made from durable materials like nylon or polyester to resist stretching and wear. Using a string line helps maintain alignment and prevents errors during construction, resulting in clean, professional-looking projects.
