FAQ

Frequently Asked Questions

The term "surface-watertight” means that the manhole cover is protected against the ingress of natural precipitation such as rain or other surface water that occurs without pressure.

We speak of a flood-proof cover when it is flooded, for example, by high water. The manhole cover remains resistant to water penetration up to a certain water column. A backwater-proof manhole cover prevents water from penetrating from the inside of the manhole to the outside.
