White furry stuff on concrete floors
Last Friday, we pulled up our hard wood floors because they buckled, we know we have a drainage problem and Also last Friday they starting digging the trenches for the drainage around our property. I noticed on Saturday that there is white fuzzy stuff popping up on the slab. I sprayed with bleach... didn't go away. Last night I scrubbed and used a mold killer ( I don't remember the name) and today it's back. What else can I do to get rid of this stuff so we can have a new floor put in our house. Will the moisture barrier under the floor help?
