      abstract = {Flooding is a frequent problem in Port Harcourt, especially in areas such as Eneka, Rukpokwu, and Eliozu. Many residential buildings in these locations suffer damage after flood events, mainly due to poor resistance of wall materials to water. This often leads to cracks, dampness, mould growth, and costly repairs, affecting both building durability and the health of occupants. This study aims to evaluate the performance of water-resistant wall systems in post-flood residential buildings in these flood-prone areas. It focuses on identifying commonly used wall systems and assessing how well they resist water and recover after flooding. The study adopts a mixed-method approach, including field surveys of affected buildings, laboratory testing of selected wall materials, and comparative analysis of their performance. Data are collected through direct observation, simple material tests such as water absorption, and feedback from residents and builders. The results show that some wall systems perform better than others in terms of durability and moisture resistance. Materials with lower water absorption and better surface protection tend to resist damage more effectively and require less repair after flooding. The study concludes that selecting appropriate water-resistant wall systems can greatly improve building resilience in flood-prone areas. It recommends the use of more durable materials and improved construction practices, as well as stronger building guidelines to reduce flood-related damage in residential buildings},
