A large Northwestern hospital has recently installed one of Fibrelite’s watertight underground enclosure systems as part of a new helipad construction. This enclosure was installed as part of a radiant heating system installed in the concrete helipad and associated walkways in order to keep these areas free of ice and snow during the winter months. The S7SB-390-WT underground enclosure system specified for the job includes a 45” x 45” square watertight fiberglass enclosure designed to mate with a 36” diameter watertight composite manhole cover installed in the concrete helipad.

The S7SB solid bottom enclosure will serve to house the manifold connecting the radiant heating system’s large array of pipework. The FL90 composite manhole cover used to access the enclosure can easily bear the loads of the heavy emergency vehicles accessing the helipad while also keeping water from draining into the underground manifold.

A number of Fibrelite’s bulkhead fittings were also installed to allow the array of radiant heating piping to enter the enclosure while maintaining the structural integrity and watertightness of the enclosure system.

Advanced Design – Multiple Applications


Fibrelite is the world’s leading manufacturer of Fiberglass Reinforced Plastic (FRP) manhole covers and underground containment systems. This sophisticated and highly specialized material is fast becoming recognized as the effective modern alternative to traditional materials such as heavy steel and concrete.

Though other containment systems and manhole covers had been considered, the following benefits meant Fibrelite’s FRP cover and enclosure were chosen for this project:
  • Lightweight covers for easy and safe manual removal
  • Cover and enclosure made from chemically inert and corrosion resistant materials
  • Extremely strong and durable products
  • AASHTO H20 & H25 tested covers
