Is it effective to use contraction joints on the base slab of a large swimming pool? What if I cast with just construction joints?

RE: Contraction joints in swimming pool base?
I would suggest the solution lies less in the effectiveness of the joints themselves and is better spent using the joints as part of a comprehensive crack minimizing solution. For instance, consult with a mix expert to minimize shrinkage cracks possibly through the use of fiber reinforcement, ensure sub base is sufficiently compacted before the pour, use waterstops in all contraction joints, and locate contraction joints at a more conservative spacing.
