I live in NC with clay soil. A problem area for me is under my deck where the soil NEVER seems to drain. I've removed the mulch installed by the builder. :-( to try and help to no avail. I don't want the deck supports to prematurely rot out from underneath us!
Is it possible/adviseable to install a membrane/barrier on top of the soil to only permit evaporation and no further water uptake?
Could/should I also add crushed rock to assist in draining the water away from this area?
