Beware of anyone who uses foundation elevations without an "as built" benchmark!
Watch one minute video about foundation elevations first and then read the text for a better understanding.
One must have original elevations to determine if a foundation has settled in one area, heaved in the other, or the slab was poured that way. In other words, you can’t tell if it has gone up or has gone down. When the operator wants to show the foundation to appear settled they put the zero mark at one point. If they want it to have heaved, they put it somewhere else. Since they want to sell piers they can make it appear that settlement is the problem. Foundation companies do this to customers every day, to convince homeowners to buy piers they don’t need. These unneeded piers will usually cause additional problems later on.
The real reason that there are so many foundation repair failures is not necessarily because of bad piers, but because piers were installed when and where they should not have been. And guess what, your warranty will not usually cover that mistake. Contact me and I will explain it all. The manipulation of elevations is one of the biggest frauds in the foundation industry. For areas of expansive soils, upheaval is more often the cause of foundation movement than settlement. In North Texas concrete beams in both slab and pier and beam (crawl space) construction are designed to be supportive and protect against settlement from minor voids under beams. Expanding soils, on the other hand, are able to push areas of the slab up essentially causing the same damage signs as settlement, only in a somewhat different pattern.
When“X” is original grade (when constructed) then “O” has settled and the slab must be lifted. HOWEVER, if “O” is at original grade then “X” has heaved and you cannot tell the difference without an original benchmark elevation, which homeowners do not have. NOBODY THAT I KNOW OF IN NORTH TEXAS HAS THAT ORIGINAL ELEVATION FOR THEIR HOME!
The foundation companies do not have the sea-level foundation elevations or benchmark, so do not buy piers based on those raw elevations. Below is a computerized level used by many foundation companies to take elevations. All it can show is that the foundation is not level. It could have been poured not level, it could have settled, or it may have heaved, or it could have done all. The least likely option is that it just settled, and if it did, this machine cannot tell you.
