Permanently protects against corrosive Hydrogen Sulfide gases present in municipal sanitary sewer systems.
Field inspected, qualified, and engineered system that has been third-party tested for corrosion resistance.
Composite FRP Rehab Panels are designed to fit the exact dimensions unique features of any large wastewater structure.
Unlike temporary field-applied coatings that must be reapplied, Composite FRP Panels are a permanent, maintenance-free solution.
The rigid panels can act as formwork to repair and reinforce walls with exposed rebar while adding a corrosion-resistant interior shell.
Composite FRP Rehab Panels by NWPX are easy to install and maintenance-free. The panels are ideal for rehabilitating existing large wastewater structures as well as for providing a corrosion-resistant lining to new structures, extending the service life by decades. The system offers a permanent and cost-effective alternative to field-applied coatings, which must be reapplied over time.
Our Composite FRP Panels consist of a PP honeycomb core with polyester fleece backing and a thick outer layer of corrosion-resistant FRP. The panels come pre-drilled and ready to be mechanically fastened to the walls of an existing concrete structure. Once the panels are securely mounted, the void between the panels and the walls is filled with high-strength grout to provide additional strength to the system. Seams between the panels and all fastener heads are sealed in a three-step process by qualified applicators providing seamless protection from the corrosive environment of hydrogen sulfide gases.
Using a 3D scanner, the interior of the structure being rehabilitated will be scanned to obtain a representative digital model. Our engineering team will evaluate the model based on the digital visuals and will dimensionally compare it to the as-built drawings of the structure. If the structure is suitable for rehabilitation, our engineering team will design a panel layout to fit the existing structure’s configurations. From top to bottom, the access hatch locations, pump discharge pipe, inlet pipes, odor control pipes, flow channels, and other features are identified with proper sealing details provided for each individual structure.
Composite FRP panels are designed to be affixed to the existing walls of the structure with stainless steel concrete anchors. Panel joints are sealed against sanitary gases by bonding FRP E-Glass over all joints and fastener heads, creating a completely corrosion-resistant system.
Composite FRP Rehab Panels are Quick to Install and Provide Permanent Maintenance-Free Corrosion Protection for Wastewater Structures.
