Is there any way I can use a concrete mixture on top of a wooden deck to seal out moisture? I suppose what I am asking for is a concrete that can slightly expand and contract, given that we have some good winters here and some steamy summers. I know they do wonderful things nowadays with additives.

The deck is 16' x32' made of 3/4" - 4' x 8' sheets and is 8' off the ground. Currently it is covered with fiberglass but there are one or two areas that have cracked. We want to correct any moisture problems before they become serious.

We had covered it with a commercial vinyl product 12' wide with overlapping seams but the seams gave way and water seeped in.

Any suggestions on how to waterproof this deck would be very much appreciated.

Thanks, Victoria

Cement is not waterproof.

Yinyl is not intended for walking surfaces.

Neither is any other waterproofing memebrane either.

Your bet bet is to use EPDM. It needs to be applied by a pro. It is a rubber sheet and can be installed with no seams.

A walk on deck should have a system of sleepers and deck surfacce over the waterproof membrane.

Even before that, is hte plywood still in acceptable condition or does it already sufer from water damage? If so, You may be wasting your money to roof it with out repairing it.
