ABSTRACT

It has been clearly identified that one of the agent that easily deteriorate building structure, weaken the strength of the component of building and shorten the life-span of building is â€œDAMPâ€, which may occur in different dimension therefore, this project is centred on causes of damp, prevention of damp and the necessary treatment needed for the structure that has been severely affected with damp in makoko, yaba area of Lagos state. This research connotes that the main causes of damp are: rain penetration, rising damp, condensation, humidity, roof leakage and lack of drainage. To achieve the objective of this study, four research questions were raised. The survey research design was adopted using observation technique. A checklist was used for data collection. Based on the findings it was concluded that there is need to prevent and treat damp in building in makoko area of Yaba local government in Lagos state so as to have an healthy environment and also to prolong life of structures. Recommendations were made for prevention and treatment of damp in this area based on the reviewed literature.

CHAPTER 1

CHAPTER ONE
INTRODUCTION
Background of the Study
Damp is the presence of unwanted moisture in the structure of a building, either the result of intrusion from outside or condensation from within the structure.
According to Don Prowler (2011) moisture in buildings is a major contributor to mold growth, unhealthy buildings, and poor indoor air quality. A high proportion of damp problems in buildings are caused by condensation, rain penetration and rising damp.
Dampness tends to caused secondary damage to a building. The unwanted moisture enables the growth of various fungi in wood, causing rots or mold health issues and may eventually lead to a sick building syndrome. Plaster and wallpaper loosens: stains from the water, salts and from mold mar surfaces.
In makoko metropolis of Yaba local government area of Lagos state, damp has been a major issues which affects building. And has put the life of the occupants at risk of health problem such as asthma, it also cause damage to their properties and also the deterioration of building. This project will help the people of makoko and its environs to know the causes of this damp, means of preventing the damp from occurring and the major problem or treatment needed for the buildings that has been affected with damp.
Statement of the Problem
Damp problems in buildings causes poor indoor air qualities, respiratory illness in occupants, falling of mortar from the affected walls, failure of building components and at times serious health effects in humans. Hence there is need to find out the causes, prevention and treatment of damp in building.
