Do fiber type manhole covers float?

Post by CherokeeUST » Wed Oct 04, 2017 7:04 am

I came across a post on LinkedIn by Zamri Idris with some advice on steps to take at a UST location during a flood event. In his post he states that the fiber type manhole covers float. Has anyone ever experienced this?

I was looking at the Fibrelite drawings and they sure look like they could float. Luckily we haven't had flooding conditions here - so no practical knowledge. I'm sure one of our pointy headed engineers (looking at Zane) could crank out a buoyance calculation on these.

We have had it happen and had to install some heavy angle iron to the underside of the cover to weigh it down.

Steel manway covers will not float I can pretty much guarantee.

Do you have any data sheets that will back confirm that statement?

Can you read or translate Greek?

Yes they will float. A few years ago we had a flood event in Michigan and a few of our customers lids went missing. Once the water receded most were recovered within a reasonable distance but one was a half mile down the street. I wish I could find the pictures.
