Good afternoon,
Thank you for your question.
Drybase® TS-PLUS Tanking Slurry is a cementitious tanking slurry, as a cement based product this is alkaline so we would suggest allowing the product time to fully dry and cure before filling with soil and planting.
I hope this helps and if you have any further questions, please let us know.
Kind regards,

Would it be safe (and effective) to use on the inside of raised beds built of dense hollow concrete blocks that will be used to grow vegetables for human consumption?
