…cover part/all of a homeowners basement wall(s), just like what happened to this woman
Notice of course the water, the basement still leaks but also the bright wall paneling or whatever you want to call it, attached to part of her block walls and, notice some mold and efflorescence on walls.
That mold and efflorescence will never go away because these interior system companies do not waterproof the walls or anything else that may be open on the exterior of a home.
The paneling and other junk (like delta membrane etc) they cover the basement walls with will also hide/conceal insects (they luv wet areas), will conceal cracks, cracks widening and so on.
And it sure looks like somebody slapped some mortar on some interior blocks and appears the walls were painted not long ago… did that help?
Have a very good idea of how money she paid for…at best, a water–diverting system. Yet seems many claim that interior systems are much cheaper than exterior waterproofing, hmm, ya sure?
Sad bunch of crooks. People getting deceived, lied to, misled every day. Even if these bubbleheads came back to her home to, supposedly do further repairs, who would really want them to try! Not me. They already misdiagnosed her problems and led her right into an interior system that did what? Come on folks. They’ve already proved their incompetence, and so did the city if they approved/okayed the permit, if that was pulled.
Here’s another good article on bowed, bulged foundation walls…don’t agree w/every word, but most of it
Some continue to tell homeowners who have horizontal cracks and–or step cracks in a wall that the cause is, settlement of the house.
In part he writes, “Whenever backfill soil is placed against a basement wall, IT exerts lateral pressure against the wall… the horizontal crack will typically transition into both ascending and descending STAIR STEP cracks near the end of the wall”
Right, lateral soil pressure can certainly cause horizontal cracks, step cracks and vertical cracks in basement walls, yep.
“Another problem with silty clay or clay soil backfill is that they tend to impede the flow of surface water down…”
Right. So the clay soil will get wet, expand BEFORE the water gets DOWN to duh drain tiles and, if one has a crack(s) in the basement wall then the water finds that, first. Drain tiles laid along the footings have nothing to do with the rain water, UP HIGHER in the soil, against a basement wall.
Zero in on the 4th paragraph here, Donan Engineering http://www.donan.com/knowledge-base/article/basement-wall-failures/ In part they write, “We have found that some walls fail after a hard rainstorm, but particularly after a sustained drought. Typically, the failure is NOT from hydrostatic pressure, but from the soil re–expanding or sloughing…”
