MANHOLES
Fiberglass manholes are increasingly preferred over concrete in new installations. The highly corrosive environment of sanitary sewer lines often leads to leaks in concrete manholes and, more critically, infiltration. Infiltration allows groundwater to enter the sewer system, placing additional strain on the infrastructure and driving up operational costs. Spark Manholes and Liners offers the optimal solution for structural infrastructure manholes and a variety of related accessories and applications.
SPARK supplies both Flat top and Cone top Manholes. The selection of the structural manhole type is based on the shell height. For cone top type Manholes, the required shell height is measured from the cone shoulder down to the bottom.
TYPE | Height Range (H) |
---|---|
TYPE (A) | 1000 – 1900 mm |
TYPE (B) | 2000 – 3600 mm |
TYPE (C) | 3700 – 7600 mm |

Manhole Covers:
SPARK produces high-strength, high load-bearing composite manhole covers, which can be customized to meet specific customer requirements, including low or zero shrinkage, electrical conductivity, fire retardancy, enhanced chemical resistance, and tailored surface finishes.
