When you install them clicked together, that creates the seam that water can and will penetrate.Tile it.

before you go down the rabbit hole to far as @Bruce Lynn mentioned see if the jurisdiction were the lots are located will even allow a surface operation within their zoning code or that lot size.. thats the first thing I would do.Being an old land man I have dealt with a ton of mineral and water rights.. there is a lot to those buggers..
