Concrete slabs
Concrete slabs
The reinforced concrete slab of the inspection manhole serves as the covering or load-bearing element of the inspection manhole.
It ensures the stability and longevity of the shaft. It is especially useful in situations where the height of the shaft does not allow the installation of a conical end.
