Interior basement systems do NOT stop water from entering exterior cracks in walls and other exterior openings in walls or above walls which IS WHY most basement leak, why many have some mold or efflorescence on parts of the walls you shttheads!
Another guy, Apple Drains, installing another interior system in a crawlspace that has ALOT of efflorescence etc on the block walls.
Installing the interior system and sump pump will NOT stop the water and salts from entering! Because the water and salts are getting in from/through the exterior, hellllo!
Another homeowner MILKED out of $20,000+ by an interior system contractor, still leaks etc
