suction forces on CS's being lifted
suction forces on CS's being lifted
(OP)
I am looking for references about suction forces on concrete slabs being lifted with a hydraulic crane. These slabs are stored and have settle a few inches in saturated soil. These slabs are to be relocated.

For purpose of research, you may want to check into "apparent cohesion", or simply "cohesion", for cohesive soils.

Reminds me of the time I loaned a pair of goulashes (buckled overshoes)to a friend who walked into a mud hole and proceeded to walk out of them. I had to go out and retrieve them. Same principles apply.

It may also break the slab, depending on it's size and strength.
I'd at least dig around the edges to below the slab underside to minimise suction.
