New Zealands First Concrete Sealed Manhole System

Hynds Drainage has recently released a range of concrete sealed manholes.
Available in 1050, 1200 and 1540mm diameters, the Hyseal manhole is designed for sewer applications where a pressure sealed leak-free system is required. Joints are factory tested to 90kPa.

A top shelf addition to the Company’s Hyspec range, Hyseal is sold with a pre-benched flange base and pre-drilled inlet and outlet holes complete with flexible rubber gasket connectors. Each precast base is customized to the specification of the job. Risers and lids are installed with pre-lubed joint seals and the system is topped with a 600mm opening ductile iron cover rated to 240kN, making it suitable for NZ Transport Agency applications.
