FRP Panels & PVC Manholes

FRP Panels​

Quick to install, maintenance-free corrosion protection for wastewater structures.​

Each half-inch thick composite panel consists of seven layers, including a high-strength honeycomb core and multiple layers of fiberglass and fleece. The outer surface is covered with FRP gel coat, the same material we use for our other lined products. The FRP gel coat is designed and tested to resist highly corrosive hydrogen sulfide gases commonly found in municipal wastewater systems. The panels are mechanically anchored to the inside of a structure and then sealed to form a gas and water-tight lining.

​

FRP panels are customized to the unique specifications of each project. Using a 3D scanner, a representative digital model of the interior structure is created, which is used by our engineering team to design a panel layout to fit existing configurations and accommodate for features such as inlet pipes, access hatches, and flow channels.

​

• Economical and reliable solution

• Field inspected, qualified, and engineered system

• Third-party tested for corrosion resistance

• Customizable design

PVC Manholes​

Perfect pipe consists of reinforced concrete pipe (RCP) with an integrated high density polyethylene (HDPE) liner that is wet-cast in the pipe wall forming a corrosion-proof barrier. The pipe is ideal in direct bury, trenchless, high loading, and high ground water applications. Perfect Lined Manhole System integrates a monolithic base and an FRP liner with HDPE protected riser sections and lid. The one-pour base eliminates cold joints and connects to nearly any plastic, clay, concrete, or fiberglass sewer pipe.

​

Proven mechanically resistant to raw sewer, Geneva Pipe and Precast’s Perfect Lined Manholes are revolutionizing municipal wastewater management. The corrosion resistant pipe and manhole system has an anchored liner that provides 100% coverage and creates a smooth laminar flow with a tight seal. Utilizing an innovative design, the joints require no field welds in most sizes and can connect to most new or existing systems. The Perfect Lined Manhole System has a design life of 100+ years in most sanitary sewer environments.

 

Corrosion-Proof Manholes

Traditional epoxy coatings are becoming obsolete due to their limitations in long-term performance. Our advanced manhole protection systems extend service life up to 100 years at less than half the lifecycle cost of outdated methods.

​

By integrating fiberglass bench protection with various riser protection systems, we provide a fully corrosion-resistant solution, impervious to aggressive sewer environments. Options include:

​

• C-900 PVC risers and Polypropylene Cor-Protect systems for rehabilitation

• Flexible polyurea bench liners for superior adaptability

• PMA Manhole System with a lined joint connection, integral seal, and load transfer for optimal structural integrity

​

Through our partnership with industry-leading concrete protection manufacturers and expert field services, we deliver durable solutions for both new and existing manholes. Whether rehabilitating in place, replacing risers, or designing for new construction, we provide the technology and expertise to ensure long-term success.
