Safe sealer or liner for concrete raised beds
I appreciate any help I can get on this: We recently built an energy-efficient greenhouse and the mason just finished building the concrete block raised beds. We need to seal or install a liner inside the raised beds to keep water (from the soil) from leaching through the seams of the concrete and we also need this sealer/liner to be safe for growing edible plants and trees (i.e. not leaching contaminates into our soil). We will mostly be growing fruit trees but plan on growing vegetables as well. Can anyone give us advice one what products would be appropriate?
Thanks so much! We look forward to your ideas.
