Fiberglass Manholes

Standard Features:

  • Constructed to ASTM D-3753 standards.
  • Fiberglass composition withstands attack of hydrogen sulfide corrosion.
  • Lightweight and structurally sound.
  • Withstand H-20 axial loads.
  • Monolithic construction and no field joints.
  • Reduces ingress into the manhole.

Eliminate Corrosion and Costly Maintenance/Rehabilitation:

  • Ordinary manholes corrode.
  • Fiberglass Manholes do not corrode.
  • Manholes resist decades of attack by hydrogen sulfide.
  • Avoid street closings, disruption, costly repairs and maintenance of ordinary manholes.

Structurally Sound – Exceeds H-10 Load Rating:

  • Fiberglass manholes have been in service for more than 25 years.
  • Many installations are in busy streets.
  • Fiberglass manholes are designed to withstand rigid requirements of AASHTO H-20 Axial Loads.
  • Fiberglass manholes will withstand far more weight than a fully loaded cement truck, meeting ASTM requirements of a minimum dynamic load rating of 16,000 pounds.

Lightweight for Easy Installation:

  • Fiberglass manholes are far lighter than concrete, about 60 pounds per vertical foot.
  • Light weight makes installation easier, safer, and less costly.
  • No need for heavy equipment.
  • Less manpower required to move the manhole.

Reduce Infiltration:

  • Ordinary concrete manholes installed in sections due to weight.
  • These joints - typically every four feet - are the source of most leaks.
  • Fiberglass manholes have no joints.
  • Available in one-piece lengths from 3 to 25 feet.
  • No joints means no joint infiltration or exfiltration.
  • Monolithic design makes installation easier.
  • Eliminates time needed to seal concrete section joints.

Will Not Float:

  • Better safety factor against float out than concrete manholes.
  • Far smaller wall thickness than concrete means a decrease in volume displacement.
  • Decrease in buoyant forces on fiberglass manholes.
