Self-supporting manhole rehabilitation method Jickboard J method
A new manhole inside an existing manhole.
The Jickboard J method is a self-supporting manhole rehabilitation technique that provides performance equivalent to that of newly constructed manholes, using only rehabilitation materials for existing manholes that cannot be expected to withstand corrosion or aging. It is a unique method that combines Jickboard, Jick grout, and Jick grid into a single rehabilitation material, offering load-bearing and seismic performance comparable to newly constructed manholes. ▼Features - It can be adapted to facilities under very harsh conditions or those requiring long-term durability. - Jickboard is a factory-molded product with a homogeneous, high-density corrosion-resistant coating that has excellent barrier properties, eliminating the risk of permeation by corrosive substances. - The joints have a double structure of molded products and corrosion-resistant seals, providing excellent durability features that prevent damage to the joint areas due to stress concentration and other factors.
