Pivoting expansion mechanisms expand the riser tight against the existing manhole frame. This extreme mechanical pressure prevents any shifting or rattling that could break the water seal over time.
Traditional brick and mortar adjustments crumble under heavy traffic and freeze-thaw cycles, allowing massive water infiltration. Solid iron risers completely minimize mortar failure.
Designed to be installed with industrial-grade epoxy adhesives. The combination of expanding expansion mechanisms and epoxy creates a completely watertight, permanent bond with the host frame.
Deploy our fully adjustable manhole risers on your next sanitary sewer resurfacing project and instantly lock out surface stormwater.
