Its own website describes below-grade water work
Found on the company's own pages: underpinning, basement lowering.
Ontario licenses nobody for basement waterproofing, so there is no licence for this site to look up, and it does not verify insurance, WSIB clearance or any warranty a company offers. Nobody here has stood in one of these basements.
