The contractor said they would use a jackhammer on the edge where the walls and floor meet to create this trench.
Now, I have some questions about this ....
Would all this pounding cause damage to the house since the drilling is done so close to the foundation footing?
Also, later on, I'm thinkiing about covering my unfinished basement walls with drywall. Would moisture and mold develop between the basement wall and the drywall?
Any advice on this would be appreciated.
