From analytical results of illustrative examples and reports of observed characteristics, it is shown that solid slabs of reinforced concrete for housing are not properly designed and constructed in the area or the zone of study, which explains the high percentage of service failures observed. Considering three possible scenarios for cor­rosion of the reinforcing steel the reliability index for six cases are reported, the results show high failure risk or significant maintenance inversions. It is concluded that for the correct design of solid slabs it is necessary to not only revise flexure strength but also to control vertical deformations, cracking due to shrinkage and permeability which implies the specification of a dense and durable concrete. Practical recommendations are presented.
