Expansive soils
Expansive soils
(OP)
Is there any relationship between the Potential Vertical Rise (PVR) and differential vertical movement(Ym).
Also despite reviewing a number of design documents in the Huston Area, I am still not crttain how they make a decision to choose a slab-on-ground and a slab on piers, based on the soil expandivity. I appreciate if someone can enlighten me about this local practice.

RE: Expansive soils
Can the PVR be derived from the differential vertical movement(ym). It seems if the slab is a square with dimension em, the ym value should be practically very near to PVR.
Also despite reviewing a number of design documents in the Huston Area, I am still not certain how they make a decision to choose the type of a slab-on-ground (super slab, floating or uniform thickness types) based on the soil propensity for vertical movements.
