I would run a water-test with a hose on the outside before any homeowner spent 1 cent.
Likely EITHER, an opening/gap has occurred AROUND the pipe on the outside of wall (whatever that is)…see photos below… and-or, an opening/crack has occurred IN that pipe on the outside/underground which allows water to get into pipe and travel inside the pipe and come back into the wall, drip into blocks.
Staying on that pipe/whatever, it could be no crack occurred IN pipe and there already was/were 1+ openings in pipe, at end of pipe etc and they thought they could epoxy/caulk/fill pipe from the inside (wrong-won’t last in the long run) to keep water from getting in. Always best to REMOVE unnecessary piping that comes through a basement wall, especially block, brick basement walls and seal/waterproof the wall, hole etc on the outside.
Would be a small job, only need to ‘do’ that area outside, NOT 1/2 or the entire wall as some think, erroneously claim.
And other times for some homeowners, the can have a gap etc AROUND a pipe on the outside of wall AND an exterior crack in the block wall OR, 1+ OTHER openings as you see in first 2 photos…
This is UNDER a BACK DOOR which was also under concrete slab…
http://picasaweb.google.com/101049034584960315932/BasementWaterproofing06#5442162385587957666 These gaps, deteriorated joints etc were under a concrete slab. Some tell homeowner to replace the slab or mudjack the slab or caulk etc along egde of house and concrete slab, won’t work! Need to, find all exterior cracks, gaps, openings and seal them all correctly
Different home, pipe comes through foundation wall, see gaps AROUND pipe that were not sealed/waterproofed correctly, they should have FIRST used hydraulic cement, then mastic and visqueen…
Explained in full to these homeowners that IF there is a crack/other opening IN THE PIPING then, water WILL get INTO the pipe and come in basement, NOT my fault, and they’ll need to get the plumber to REPLACE the parts of exterior pipe that have cracks etc.
Or in the future, a crack or other openings could occur in the exterior pipe which then would allow water in basement again.
Again, x-amount of water ‘could be’ getting into that pipe, on the outside through the end of pipe or through any openings etc IN the pipe, outside.
Have also seen a water line and sprinkler line/hose that comes through the basement wall… a crack etc occurred IN the line–hose WHERE it came through the wall, yes, inside the a block wall which then allowed water to drip down into other blocks and eventually onto basement floor PLUS, they did have exterior gaps etc on the outside of wall, where the pipe comes through wall so, they needed to get someone else to replace line–hose and then we did the waterproofing on the outside of those areas.
Please see these photos, similar to pipe photo posted BUT a little different when looking at inside wall because this is a POURED wall, then please observe OUTSIDE photos 7–15 in 2nd link
Pic’s 7–15 under a deck…where the pipe comes through the wall
So someone tried filling this pipe on the INSIDE of basement/wall but THAT did not stop, did not keep water from getting INTO pipe on the outside. Remove the pipe and seal/waterproof all exterior openings, no more water.
Zero in on photos 14 and 15!!! See the pipe. see the WATER in the pipe? lool
