Manhole cover VIATOP NIVEAU - Limitation of the surface water entries
Water tightness tests on VIATOP NIVEAU manhole cover confirmed that water could ingress through the hinge housing.
For applications where water ingress needs to be limited, SG PAM proposes a version of the VIATOP NIVEAU, which incorporates a plug in the hinge housing.
For applications where the total prevention of water ingress is required it is recommended to use the PAMTIGHT.
These plugs for manhole cover VIATOP NIVEAU, either are directly fitted in factory and in these cases the manhole cover are specific references and identification, or are provide of a “kit plug” intended to equip the manhole cover already installed.
The fact of equipping a manhole cover VIATOP NIVEAU with a plug does not modify of anything its characteristics.
