We have a lot of heaving in our area. Some locations around town are worse than others. Olathe south of Santa Fe and east of I-35 is one hotspot. So is west of K-7 and north of K-10. So is Briarcliff north of old downtown airport and over by the ballpark and behind the IRS / Bannister Center off 95th. Where was this one at.
I’ve done a bunch of these and most of the times they benefit most to start by having a really good foundation company like Kansas City Master Company or Spartan Foundation do a slab type survey … Then head to the PE if needed for design.
We got a handful of good PE’s for this type work and a whole lot of not so good ones. The last 2 of these I’ve been called in on, had over 2"-3" of heave, raising poles, I-beams, 2nd floor cabinetry & floors, doors that had been cut off to close, etc. Each time they’d had a PE their REA had recommended to them AND had paid $350-$450 and all they had was “The floor has heaved, I think we need soil boring and then a foundation contractor to repair”.
