Targeted Structural Repairs Without Full Pipe Relining
When pipeline defects are isolated to a specific location, sectional repairs provide a fast, cost-effective alternative to full-length relining or excavation. Draintech Solutions delivers trenchless sectional rehabilitation using proven packer systems to permanently repair cracks, fractures, displaced joints, infiltration and localised structural defects while keeping disruption to an absolute minimum.
Our experienced technicians utilise industry-leading robotic preparation equipment and structural repair systems to restore the integrity of damaged pipelines without the need to replace the entire asset.
When is a Sectional Repair the Right Solution?
Sectional repairs are ideal for addressing:
- Cracks and fractures
- Open or displaced joints
- Infiltration and groundwater ingress
- Root intrusion following removal
- Localised corrosion
- Minor structural failures
- Defects identified during CCTV inspections
By repairing only the affected section, clients can significantly reduce project costs while extending the service life of the existing asset.
Our Process
Every repair begins with a comprehensive CCTV inspection to accurately locate and assess the defect.
Our team then:
- Cleans the pipeline using high-pressure water jetting
- Removes roots, intrusions or obstructions using robotic cutting equipment
- Installs a resin-impregnated repair patch using an inflatable packer
- Cures the repair in position
- Verifies the completed installation with post-repair CCTV inspection and reporting
Each repair is completed with minimal disruption to surrounding infrastructure and without excavation in most situations.
