Lesson 04 : Damp Proofing : Methods And Materials

Introduction

A house is not just a building, it is a place of dwelling where comfort is the most important requirement. It should remain dry, free from moisture and unhygienic conditions. Dampness in the building is one of the most unwanted conditions. Dampness is the presence of hygroscopic or gravitational moisture. Dampness gives rise to unhygienic conditions, and also reduces the strength of structural components of the building. Damp prevention is one of the important items of building design. Hence, this is considered to be one of the important items of work in the construction of a building. The treatment given to prevent leakage of water from roof is generally termed as water- proofing, whereas the treatment given to keep the walls, floors and basement dry is termed as damp – proofing. Every building should be damp proof to allow the inmates enjoy every moment of their life in it.
