PREDL - Manhole Rehabilitation Solutions
PREDL specializes in innovative solutions for the rehabilitation of sewage manholes, offering durability and resistance against chemical and environmental factors. They employ diverse methods based on site conditions, including SCAN-lining, which utilizes laser technology for precise surveying and documentation. Among their solutions is the manhole-in-manhole system, which involves a GRP rehabilitation base-liner paired with a fiberglass-reinforced plastic (FRP) pipe. This approach is ideal for severely deteriorated manholes and allows digitization to update structures according to contemporary standards. The Flexliner system ensures quick, trenchless rehabilitation by inserting and unfolding a liner into the manhole, reinforced with a Corprotect lining for added durability. For structures with unique demands, PREDL also provides custom-designed FRP panels. These panels offer notable resistance to deformation and facilitate easy transport while ensuring lasting protection against corrosion.
PREDL - Model FLEXLINER - Trenchless Manhole Rehabilitation System
The PREDL-FLEXLINER system offers an innovative solution for trenchless manhole rehabilitation. This system uses a wastewater-resistant synthetic material, specifically polyurea, to create a durable manhole base liner that is inserted through the manhole cone non-destructively and expanded to its original size. It provides a cost-effective alternative to complete manhole replacement by employing a 3D laser scan of the existing structure to produce a custom-fit liner. The liner is secured with a specialized grout, FLEXgrout, to ensure a robust bond, aided by its textured design. Additionally, connections are strengthened with a stainless steel sleeve and EPDM seal. If required, further manhole structure reinforcement can be achieved using PP-CORPROTECT. PREDL-FLEXLINER ensures minimal disruption during installation, while the precise 3D modeling and chemical-resistant materials promise longevity and reliable performance.
