By Damp Proofing Courses (DPC) Continuous layer of impervious material between source of dampness and building component Path of water up walls is blocked by builders incorporating an impervious layer into the wall at low level ‘damp roof courses’ Have been made of various materials including things as slates, engineering bricks and bitumen. Damp in buildings may be apparent from: Damp patches. Mould growth. Mildew, salts, staining and tide marks. Damage to surface finishes, such as blistering paint and bulging plaster. Corrosion and decay of the building fabric. Slip hazards. Frost damage. Poor performance of insulation. Damage to equipment, or electrical failure.
The Official Definition of an Old Building used to be "Built before ". That didn't really help anyone understand what made them different. It's now defined as: It's inevitable that you will find dampness somewhere in an old house. Nothing lasts forever, but despite English weather, our old buildings stand the test of time better than any. Structural dampness 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. A high proportion of damp problems in buildings are caused by ambient climate dependent factors .

This book deals, first of all, with properties of the more common building materials, and then considers performance of the main building elements in relation to moisture control or exclusion.
Condensation and rising damp are looked at in detail, and a chapter on diagnosis provides a handy checklist to the likely causes of the main problems of Cited by: Water in Buildings: An Architect's Guide to Moisture and Mold is a detailed and highly useful reference to help architects and other design professionals create dry, healthy environments, without jeopardizing a project with poor liability : William B.
Rose. MOISTURE DEFINITIONS 1. Studies use various qualitative terms to denote the presence of excess moisture in buildings. These include dampness, condensation, building dampness, visible dampness, damp patches, damp spots, water collection, water ponding, and moisture ss—however it is expressed—is used to signify a wide array of signs of moisture damage of variable spatial extent.

Rising damp in buildings may be defined as the vertical flow of water up through a permeable wall structure, the water being derived from ground water.
The water rises through the pores (capillaries) in the masonry by a process loosely termed ‘capillarity’. In other words the masonry acts like a Size: KB.

It lists the causes of dampness in buildings and explores the consequential effects of that dampness on the fabric, the maintenance of protection against dampness, and the remedies which the detrimentalFile Size: KB.
Damp in buildings is a subject that can be difficult to get a clear and conclusive answer on. This small (but comprehensive) book classifies the main causes of "damp" (often condensation) in buildings/5(10).
At Danford Brewer & Ives we specialise in treating damp problems in buildings, usually old buildings and sometimes listed buildings. The oldest and listed properties often provide the most interesting work for us.
Our usual jobs are often in Victorian, brick or stone terraced houses located across Yorkshire & Teesside. The view that rising damp is a myth may cause building surveyors to form a view that it is not worth learning how to properly survey for rising damp.
The supposition that rising damp is a common problem has led to a glut of poorly trained industry surveyors and widespread misdiagnosis due to over reliance on hand held electrical moisture meters. Damp is more commonly associated with poorly ventilated homes that, more often than not, are not fitted with central heating — but it is also an issue that affects many commercial properties in the UK.

Evaporation: The transformation of liquid into a vapor, generally as a result of rise of temperature, is the opposite of condensation. Moisture in damp soil, such as in a crawl space, can evaporate into the air.
Hot, moist air has a higher pressure than cool, dry air. A large amount of vapor pressure results from a high moisture content. The vapor pressure at any moisture content is equal to the sum of all individual vapor molecule pressures.
A large amount of water vapor creates considerable force; in fact. Rising damp is the common term for the slow upward movement of moisture in the lower parts of walls and other ground-supported structures. It is an important cause of wetness in buildings.
