Pier and Beam Foundation Repair - Engineer vs contractors - Who's correct?

We have an 1899 Eastlake Queen Anne on a pier-and-beam foundation in the northeast part of Texas. A foundation inspection by a structural engineer unsurprisingly indicates a need for re-shimming. He also recommended completion of a plastic sheet ground moisture barrier that currently covers about half of the area under the house. However, multiple foundation contractors have told us that the moisture barrierĀ is not necessary and may even be detrimental as it prevents the soil from drying fully.Ā  To cover or not to cover, that is the question!

Paula,

You have to make sure that the soil is dry before putting plastic over it. I have a Victorian house that is old than your home. And we have not had any issues with not having plastic. Our basement is very dry and dusty. We do have a commercial grade de-humidifier in the basement in case it does get wet. It stay off all the time so far. It is up to you as what you do with your own home. If you find that you have moisture on the bottom side of the floor joists, then it needs to have the moisture removed and plastic covering the dirt floor. If the dirt floor is close to the floor joists, then you would want to install the plastic sheeting. I would use the heaviest weight as possible.
