Waterproof underside of t&g deck

Anyone have any suggestions on waterproofing the underside of a T&G deck. I need to prevent any water from coming through the area below and it is a post construction application. This is not new construction.

Have you Googled under deck waterproofing systems or something close? There are a bunch of companies that provide systems for your project.

Make a picture, show a pictures. How do you think it is possible to give you any help without seeing?

T&G does not prevent water from coming down.
