Available in two height options, this circular riser is designed to sit above a compatible manhole structure and provide additional height while maintaining a clear 600mm access opening.

Main Benefits:

• Two Height Options: Available in 60mm or 80mm heights to suit different site and finished-level requirements.
• Circular Design: Matches round manhole installations for a consistent and practical fit.
• Maintains Access: The 600mm opening preserves clear access to the manhole below.
• Strong Precast Construction: Manufactured from precast concrete with reinforcing steel for durable, long-term use in permanent infrastructure installations.
• Efficient Height Adjustment: Provides a simple way to raise the manhole level without replacing the main chamber.

The Round Manhole Riser is a practical choice when an existing manhole needs to be raised to match the surrounding finished surface, while keeping the access opening clear and consistent.
