find,locate how/where water FIRST enters,this is what all should do.
i`m implying that over the last 30 years that most(not all) homeowners problem(s) are on the outside. Cracks,open mortar joints,openings around basement windows etc etc etc.
It`s what TIME has shown us.
Want to see more pictures of homeowners actual-problems?
Some folks have 'other' reasons as to why-how water winds up on the bsmt floor. Some include a blockage in lateral line between the street and house, many(not all)remedies for this was having an honest-exp`d plumber snake the storm trap clean out, cost usually $125-200.
Others have a blockage in tile that empties into their sump PIT. EITHER, need to snake that tile back under floor and/or, sometimes there are no openings-holes up higher in SIDE`s of PIT-wall, just under the bsmt floor. Need to drill-create holes in pit-wall to allow water to get into pit, otherwise the water can accumulate under the floor and back up,rise through floor crack(s) or along wall-floor joint.
Others may simply have some sort of leaky plumbing fixture. Still others may have a condensation problem, especially if they placed a sheeting right up against concrete basement wall(s). But like i say, and know, most (not all) HO`s problems/causes are on the outside.
Many only have 1 crack, say at-near a corner or have 1 wall that leaks along wall-floor joint due to exterior cracks...so,they will only need to repair/waterproof the corner or, 1 wall. Part of problem is there are some companies who bs people into more work/footage than needed.
Find,locate the problem-source, then fix it.
In my honest opinion, Bent.injections do not correctly repair/fix/waterproof the exterior crack(s), or other openings into/through wall, like a block wall. Sometimes there are gaps-spaces where a service line enters through wall.
Bent-injections don`t plug/patch/repair the dumb cracks and other openings that allow water to enter. They also do NOT remove expanding-contracting SOIL, they don`t remove ROOTS or porch footings...all these cause many walls to crack,leak or possibly bow inward.
Gotta physically remove these problems/causes and physically repair/waterproof cracks etc.
