Resintuff B125 Triangular Manhole Cover, 700mm x 700mm, 12.5 Ton Composite

Resintuff B125 Composite Cover

The Resintuff Triangular Manhole Cover provides a high-strength access solution for underground utility networks, drainage systems, and inspection chambers. Engineered from advanced composite materials, this 700mm x 700mm unit meets B125 load requirements, supporting up to 12.5 tons of gross vehicle weight. It serves as a reliable alternative to traditional cast iron lids in residential and light commercial environments.

Built for the Job

This hardware is specifically designed for areas where weight, corrosion, and theft are primary concerns on the job site. The triangular configuration utilizes a three-point suspension system to eliminate rocking under traffic, which reduces wear on the frame and minimizes noise. Contractors typically install these units in footways, pedestrian precincts, and private car parks where light delivery vehicles or passenger cars operate.

• Installation in residential driveways and estate service roads.

• Access points for telecommunications and electrical ducting.

• Stormwater and sewage inspection chambers in urban areas.

On-Site & Workshop Notes

• Ensure the frame is fully bedded in a high-strength mortar mix to prevent movement under load.

• Clean the seating area of the frame thoroughly before final placement of the lid to ensure a flush fit.

• This composite material allows for RF signal transparency, which is helpful when housing smart water meters or wireless sensors.

• Use standard lifting keys for removal; the lightweight nature of this component reduces the risk of back injuries during maintenance.
