Terrazzo leaking

have an old terrazzo bathroom floor the shower stall is leaking through tiny cracks to the woodwork underneath..Are there any products that will seal the shower stall and stop the water penetrating?

If you are talking about grout lines between the product, the grout will have to be removed and regrouted with a sealer.

If it is the product itself that is cracking, then you will most likely have to use a product that provides either a clear epoxy sealer or cover the finish all together.
I'm just a plumber and I'd refer you to a pro in that profession for further advice.

I had the same problem . . . used an epoxy sealer and it worked (until I ripped the ugly mess out of there . . .)
