Sorry if I missed it, but how do these inside systems address water entering walls from the outside? Seems like they're a much more convenient way to go about the problem, but are they as effective?
This business is geographically sensitive, we deal almost exclusively with interior footing drain systems, IMO the most reliable effective system. But I understand in other locals it is not the accepted approach.
The area I work in is all concrete foundations, no blocks. Concrete foundations can leak down the wall from cracks or holes but not as much as a block foundation can. Some older concrete foundations or stone foundations can have multiply leaks through the wall, we install what we call a weep joint, which is a geotextile that leaves a gap between the floor and the wall to allow any seepage down the wall to pass down under the floor to the footing drain.
The jobs that Ampsucker and frwinks did are very comprehensive and effective but would be expensive to hire a contractor to do, I would only recommend such an involved job like that for the block foundations like they have.
For a contractor to do a job that involves complete excavation around a house foundation by OSHA standards would be cost prohibitive in most cases. Not impossible, but very expensive, I've heard of jobs like that in the $20,000.+ range, never done one myself.
