My two floor building is built on top of clay ground.
I asked my engineer , would it be worthwhile to do plinth protection around the building. so we can avoid rain water from seeping in to the foundation.
My engineer responded that it's not required as the building is built on top of clay ground literally the building is standing on top of damp ground besides absorption capacity of clay is low.
But I was not convinced. So I thought I'd get your insights into this.
