FiberstrongTM GRP manhole is a vertical underground shaft used as an access point for multipurpose aspects of storm and sewer pipeline systems such as:
Inspection and maintenance of the buried pipeline systems
Ventilation of sewer in order to allow the escape of gasses
Joining and changing direction or alignment of flow
Accommodation of pumping stations
Cleansing and flushing
Compared to concrete manholes, FIBERSTRONGTM GRP structural manholes can offer far greater benefits and advantages to the parties involved: end users such as Governmental Authorities as well as contractors and consultants.
Performance is maintained throughout the Manhole design life (100 years) with no need for any maintenance as fiberglass is a non-corrosive material.
Its lightweight property facilitates the handling procedure as well as helps in reducing time and cost during transportation and installation.
Ease of adding extra channels or backdrops if necessary.
No degradation on the outer and inner layers of the manhole (peeling of inner liner, cracks, etc…)
