TL;DR
A sump pump basin is the collection vessel in which a sump pump sits and operates, sized so the float switch has room to travel freely and the pump starts only after a useful volume of water accumulates. Undersized or debris-filled ones cause the classic failures: floats hanging up on the liner wall, short cycling, and gravel jamming the impeller, so a solid bottom or a paver under the pump is standard practice.

During foundation waterproofing it is set flush with the slab, with the discharge line, check valve, and sealed cover completing the assembly.
