Can a waffle slab support a swimming pool nearby?

A waffle slab itself doesn’t directly “support” a nearby pool — the pool has its own independent structure — but proximity genuinely matters for how both are designed, since a pool can influence surrounding soil moisture conditions.

Coordination between your structural engineer and pool designer/builder is genuinely worthwhile when a pool sits close to your home’s foundation, ensuring both structures are properly designed accounting for their proximity.

This is exactly the kind of site-specific consideration your engineer factors into your waffle slab’s design if a pool is planned nearby, rather than designing the slab in isolation from that context.
