Pipe bursting is a trenchless method used to replace old or damaged underground pipes. It involves breaking apart the existing pipe while simultaneously installing a new one in its place. A bursting head is inserted into the old pipe, which expands and fractures it, allowing the new pipe to be pulled through. This technique minimizes surface disruption, making it ideal for urban areas where digging up streets or yards would be problematic. Pipe bursting is commonly used for various types of pipes, including sewer and water lines, and is considered an efficient and cost-effective solution for pipe replacement.
