Within about the last year, I raised the issue I think in this discussion forum about the pros and cons of using a sheet of fiberglass (6 foot x 4 foot ±) as a material to cover graves in a cemetery. The fiberglass would be placed at grade level (not at casket level). If the graves are to be covered, I would have thought concrete would have been a better, although more expensive material with which to cover them.

The subject has been recently raised again in committee, and has been run by me as a retired structural engineer.
There were a number of good responses given when I last posted this in this forum as to why this was not a good idea, viz.

a) fiberglass panels subject to damage if any grave excavation equipment accidentally ran over them;

b) how to be sure strong winds would not make the panels airborne;

c) degradation of the fiberglass under sunlight (although this might take a many years).

The proponent is proposing that the panels be anchored down against wind uplift, by a one one inch downturn around the panel perimeter, which would be pressed down into the soil when the panel is first installed, to resist wind uplift


I expressed skepticism about fiberglass panels but I have been told by a number of people whom
I respect, that they have seen such panels over graves and that they have been in place for 20 years or more.

My question now: How do I get back to those responses that were put on the forum when I first raised this issue on this forum?

If I cannot get back to the forum where I first asked questions on this subject, can current readers please respond to the above items?


I would like to print responses out to convey to the person in the committee who is proposing the idea.

Thanks very much.

a> Fiberglass is not a structural material, so sure
b> Is this really an issue in Ontario? You'd need surface winds high enough to lift these panels, which weigh 6x4*16 oz/ft^2 = 32 lb?
c> One can coat vulnerable materials with less vulnerable materials; Kynar seems to work pretty well w.r.t. solar resistance for aluminum roofing.
