Inspection manhole extension for BOLT tanks

The superstructure is designed for BOLT tanks and is used when a deeper foundation is required for the tank.

The Bolt superstructure allows for the extension of the inspection manhole in a rainwater or waste water tank. This allows a deeper foundation for the tank and makes use convenient. The extensions are dedicated to Bolt tanks with capacities from 1000 l to 7000 l. The superstructure is easy to install and perfectly adapted to the basic dimensions of the tank, allowing for a smooth installation without modifications.

The extension is made of polyethylene, which is resistant to adverse external conditions, guaranteeing a long service life.
