For the record in over 40 years of building I have not come across concrete strength failure. It's always either defective design or poor workmanship or both. How do you differentiate between them? So if a slab was designed to be half as strong as it should you would not expect it to affect the movement? Slabs are not 100% rigid and bend and warp just like anything else. Surely you would want a slab to reach its designed strength and be as rigid as possible unlike my house where one side has lifted a great deal compare with the other. I'm not arguing but you have just stated that the strength of the slab has no impact on movement. Re: Warning about suggested repairs of slab heave 20Jun 23, 2012 8:10 am Yes, if the concrete is under strength slab stiffness will be reduced but in foundation heave it will make no real difference. I have seen slabs with heaved corner or a side and slabs with tilt across the whole house. It does not matter how strong the concrete is or how reactive the soil is because if there is no change in moisture content there will be no movement. This is why I believe that on reactive soils (among other precautions) a concrete apron around home is a must as a part of the design and cannot be an optional extra, or be left out for the owner to do.
