Sewer damage in construction projects: methods for inventory and prevention

In construction projects and infrastructure work, it is essential to consider existing underground infrastructure such as sewers. Sewer damage brings many additional problems, such as water damage, inconvenience to local residents and environmental pollution. It also leads to project delays and additional costs. By using advanced technologies, thoughtful planning and effective preventive measures, risks can be anticipated and prevented.

Detailed soil survey

Before a construction or renovation project begins, it is essential to have a detailed overview of underground infrastructure. Innovative technologies such as ground penetrating radar, also known as Ground Penetrating Radar (GPR), and 3D scanning provide a reliable and accurate method of determining the location of underground sewer lines. With GPR, underground structures can be detected without digging. This significantly reduces the risk of unexpected damage. 3D scans help provide a complete picture of the underground situation, including potential risks such as unstable ground layers or degraded sewers. By using these technologies at an early stage, potential problems are detected in a timely manner. This approach is particularly valuable in urban areas, where underground piping systems are complexly intertwined.

Camera inspection

For underground work, it is a good idea to check the condition of the sewer system in advance so that problems can be remedied at an early stage. Camera inspection makes it possible to detect cracks, blockages and other defects without breaking open the infrastructure. In this technique, an inspector runs a camera through the sewer system to identify the bottlenecks. Real-time images provide a clear understanding of the condition of the sewer, allowing for targeted solutions. If damage is discovered, repairs can be made immediately. This technique is used to reduce the risk of escalation and serious damage. 

Replacement of obsolete materials

Older sewer systems, such as those made of vitrified clay pipe or concrete, are often prone to wear and damage. Replacing these materials is crucial to prevent leaks and subsidence. Modern alternatives, such as plastic pipes, are more durable and easier to install. This significantly extends the life of the sewer.

One of the most innovative methods in sewer management is relining. This involves inserting a new inner layer into existing sewer pipes. This results in a fully functioning pipe, with no cutting or breaking required. This technique not only saves costs, but also minimizes inconvenience to local residents. Relining is particularly suitable for urban areas where traditional methods are impractical.

Protection of infrastructure

During construction projects, existing sewers are often at risk of damage from heavy machinery, vibration or landslides. Placing protective structures around sewer pipes can prevent this. Consider concrete jackets, reinforcing materials or temporary shuttering. These measures provide a physical barrier against mechanical forces and reduce the likelihood of cracking or subsidence. The use of protective equipment is especially important in areas with intensive construction activities or heavy loads.

Preventive monitoring by professionals

Engaging a professional sewer service is a smart investment to prevent sewer damage and ensure infrastructure sustainability. Experts have the knowledge, experience and specialized equipment to perform accurate inspections, implement effective protective measures and act quickly when problems arise. By working with a professional sewer service, construction projects can not only run more safely, but also meet the highest standards of quality and environmental protection. This saves time, costs and prevents long-term complications.
