Double-Wall Polyethylene Manhole

Double-Wall Polyethylene Manholes are engineered as access points for underground wastewater, drainage, water, telecommunication, electrical, and utility networks.

The reinforced double-wall polyethylene structure provides reliable mechanical performance while maintaining a relatively low weight compared with conventional concrete structures. Each manhole can be designed according to installation depth, pipe configuration, network layout, and specific project requirements.

The smooth internal surface helps reduce sediment accumulation and facilitates inspection, cleaning, and maintenance operations.
