Hi,
I need to patch some voids in a concrete foundation that had a
bentonite clay waterproofing material applied to it. The bentonite
clay is quite sticky and seems difficult to remove; is there an easy
way to get it off? It clogs up a wire brush quickly, and a normal
water hose isn't powerful enough to get it all off. I don't have a
power washer and would prefer to avoid renting one for the small area
I have to do. Any suggestions would be helpful.
Cheers, Wayne
