Overhead Defects

Rooftop pools and other similarly elevated swimming pool structures present unique sets of considerations that must be thoroughly addressed by anyone involved in their design and construction. As was discussed in the first article in this two-part series ("Elevated Engineering," click here), it is common for these watershapes to be constructed inside a concrete vault or supported on a concrete structural slab - either of which is usually
