In time, hydrogen sulfide will eat away at the walls of the manhole, which can lead to:
- Groundwater intrusion
- Exposed rebar
- Missing brick and mortar
- Weakened structure strength
SpectraShield is a patented, proven manhole-lining system that rehabilitates manholes damaged by the effects of hydrogen sulfide, and protects newly constructed manholes from suffering a similar fate.
Because of SpectraShield’s ease of application and rapid curing, bypassing, traffic disruption and other installation costs are minimized.
A typical manhole can be treated in less than an hour.
SpectraShield can be the ideal solution for:
Most threats to a manhole, and the wastewater network it belongs to, can be traced to the presence of hydrogen sulfide trapped in the system. This noxious gas takes up residence along the walls of a manhole where it begins to erode the brick, mortar and concrete construction.
