Bell-Bottom vs deep piling in SE Houston (Pasadena/LaPorte)
Bell-Bottom vs deep piling in SE Houston (Pasadena/LaPorte)
(OP)
Y'all,
I am a newbie - so excuse my lack of expertise. I remodel homes and have never worked on a home with a foundation problem. Recently, I have been looking at home with a 3" drop through the center of it and have been trying to figure out if the SouthEast Houston area/La Porte/ Pasadena soil makes either:
1) Bell-bottom 12ft
or
2) Deep piling
the better solution.
Anybody have any knowledge of that area or advice?
Thank you in advance,
Meweinha

I've also served as an expert witness in a lot of foundation claims, some of which included inexperienced underpinning contractors. And badly botched repairs. No offense, but you "sound" inexperienced, so proceed with extreme caution. Or you may ruin your business - and someone's home!
Underreamed piers ("bell bottomed") are far more common, but the steel piles (like Perma Jack) can also work. Each situation is different. Some parts of southest Houston / Pasadena / LaPorte have highly plastic clays with lots of slickensides (weak failure planes) within them, and a shallow groundwater table. And lots of sand pockets, seams and partings. These soils are difficult to bell in - collapse is a real problem, so the jacked steel pile is a better choice for those sites.
Okay, I've (sorta) answered your question - now answer one for me. Has this house been releveled before, or was built before about 1968? The slab's shape that you described (...a home with a 3" drop through the center of it...) is characteristic of a house that was only piered around the perimeter. It could also indicate the loss of ground beneath a slab where the cast iron plumbing is badly corroded. Some of the soil beneath the slab has been carried into the broken sewer, and the use of the plumbing has carried the soil away.
Anyway, I'd excavate at the corners of the home to be sure that it wasn't piered before. Let us know what you find -
