Resintuff 300mm x 300mm Square Fiber Composite Manhole Cover

Resintuff 300mm Square Cover

The Resintuff Fiber Manhole Cover provides a high-strength, non-corrosive solution for accessing inspection chambers and drainage systems. This 300mm x 300mm square unit utilizes fiber-reinforced composite technology to deliver a superior strength-to-weight ratio compared to traditional concrete or cast iron alternatives. It serves as a reliable seal for sewer lines, septic tanks, and cable ducting in residential and light commercial environments.

Built for the Job

Site supervisors and plumbers specify this composite lid to eliminate the risks associated with heavy lifting and metal theft. The material composition offers zero scrap value, effectively deterring vandalism on public or unattended job sites. Its lightweight nature allows a single technician to remove the cover for maintenance without specialized lifting equipment. The square frame design integrates cleanly into paved walkways, driveways, and landscaped areas, ensuring a flush finish with the surrounding substrate.

• Sealing residential inspection chambers and domestic drainage junctions.

• Protecting underground utility access points for electrical or fiber optic cabling.

• Replacing rusted or cracked cast iron covers in corrosive environments.
