Jewitt Masonry

I had to stop Jewitt Masonry from replacing 2 poured concrete sections, against my foundation, with interlocking blocks. How is that level of incompetence allowed on home stars? How will interlocking blocks stop my basement from flooding? my neighbour owes me thanks for saving his basement. If I had not checked, I would have had to call the city as to my options, what to do when a neighbours contractors work floods your basement? Any discussion is met with foul language and"get back in your house!" So you cannot see what kind of job they are doing..
