  • Thermal and Moisture Protection: Keeping the Weather out Internet Course
    Rich Text Editor,editor1 http://www.licensetobuild.com/web-class/controls/?mt=coursemanagem... Thermal and Moisture Protection: Keeping the Weather Out Internet Course Learning Objectives Summarize the key elements (either natural or mechanical) of a properly ventilated structure. List and describe at least three specific installation techniques and/or materials that contribute to a properly constructed roof system. Outline at least one design strategy based on "best practices" for the construction of buildings in areas with high humidity. Identify and implement proven methods that will effectively divert moisture from the foundation of a structure. Keeping the Weather Out Protecting buildings from weather and moisture related problems is important for all building professionals. In areas of high humidity, (and ALL Florida counties are considered "warm humid counties" by the Florida Building Code: Energy Conservation 301.2), it is even more important that builders, their employees, and their subcontractors use “Best Practice” procedures to carefully install thermal and weather resistant components. Because of the potential for loss due to consumer complaints and claims, it makes sense for contractors to be trained in moisture control for the homes and buildings they are constructing or renovating. Major performance objectives. One objective of a building envelope system is to provide moisture control. Construction of a building envelope system needs to incorporate methods and materials that prevent or minimize the impact of moisture intrusion. The photo below shows typical damage caused by poorly installed or maintained building envelope components! Too often, exterior shells are simply sealed up without regard for proper installation of house- wraps, flashing and ventilation.

  • Lime Plaster & Plaster Lath for Damp Buildings
    Lime Plaster & Plaster Lath for Damp Buildings Lime Plaster & Plaster Lath for Damp Buildings Surveying for Damp Issues with Historic Buildings. Buildings fall into two categories for the purposes of surveying for damp: I. Modern buildings built with a damp proof course and barriers to rainwater penetration. II. Old buildings built prior to mid to late 19th century depending upon the region of the country. Old buildings relied on the walls breathing and shedding moisture before damp became a problem. Damp Proofing Old Buildings In old buildings, walls were built to such a thickness that normally damp would not penetrate to the inside. The joints were always of lime mortar or earth and were more porous than the building’s structural elements comprising brick, stone etc. Consequently the joints would drain and shed water by evaporation, therefore not allowing damage to these structural elements. The joints were the sacrificial element of the building. Because lime and earth mortars are so porous, timber in contact with these mortars is less prone to decay than when bedded in cement mortar. Historic houses, when built, were able to breathe and shed water. They were also heated by coal or log fires in an open fireplace which promoted rapid air changes by way of air being drawn out through the chimney. Windows and doors were not sealed as they are today allowing air movement into and out of the building. Internal finishes were lime washed which allowed surfaces to breathe and, although it would discolour when damp, it would not peal off the wall like wall paper nor blister like modern paint.

New Delhi PRELUDE Building Bye-Laws are legal tools used to regulate coverage, height, building bulk, and architectural design and construction aspects of buildings so as to achieve orderly development of an area. They are mandatory in nature and serve to protect buildings against fire, earthquake, noise, structural failures and other hazards. In India, there are still many small and medium sized towns which do not have building bye-laws and in the absence of any regulatory mechanism, such towns are confronted with excessive coverage, encroachment and haphazard development resulting in chaotic conditions, inconvenience for the users, and disregard for building aesthetics, etc.

  • Damp Proofing Or a Damp Proof in Construction Is a Type of a Moisture
    DAMP PROOFING Damp proofing or a damp proof in construction is a type of a moisture control applied to building walls and floors to prevent moisture from passing into the interior spaces. Dampness problems are among the most frequent problem encountered in residences. MATERIAL USED FOR DAMP PROOFING 1. Property of the material An effective damp proofing material should have the following properties 1. It should be impervious. 2. It should be strong and durable and should be capable of withstanding both dead as well as live loads without damage. 3. It should be dimensionally stable 4. It should be free from deliquescent salts like sulphates chlorides and nitrates 5. The material should be reasonably cheap. 6. The material should be such that it is possible to carry out leak proof joining work. 2. Classification of material The materials commonly used to check dampness can be divided into the following four categories a) Flexible material Material like bitumen felts (which may be Hessian based or fibre/glass fibre based), plastic sheeting (polythene sheet) etc b) Semi rigid materials Materials like mastic asphalts or combination of materials or layers. c) Rigid materials Materials like first class bricks, stones, slates, cement concrete etc d) Grout materials Grout consists of cement slurry and acrylic based chemical or polymers. 3. Material used for damp proofing Following are the materials, which are commonly used for damp proofing. 1. Hot bitumen This is a flexible material and is placed on the bedding of concrete or mortar. This material should be applied with a minimum thickness of 3 mm.

  • Damp Proofing Material
    Damp Proofing Material 1- Flexible Materials: The materials, which do not crack and deform their shape when subjected to loading, are called Flexible Materials a- Bitumen Mastic (Mastic Asphalt) It consists of asphalt or bitumen mixed with fine sand in hot state to form an impervious mass. Due to this consistency it can be spread (when hot) to a depth of 2.5cm to 5cm, which sets on cooling. It provides good impervious layer but special care is needed in its laying. b- Bitumen Felts (Sheets): It consists of 6mm thick sheet of bitumen prepared in rolls having width equal to that of brick wall. c- Hot laid Bitumen: This material is used on a bedding of cement concrete or mortar. This should be applied in two layers at the rate of 1.75kg/ m2 of the area. d- Metal Sheets: Metal sheets of Copper, Aluminum, or Lead are used to prevent dampness, but they are costly. Sheets of these materials are used through out the thickness of the wall. The sheets of Lead are laid over Lime Mortar and not with Cement Mortar due to the chemical reaction of Cement over the Lead. The sheets of metal should be coated with asphalt. The thickness of the sheets should not be less than 3mm. 2- Rigid Materials: The materials, which do not resist transverse stresses and cracks when subjected to sever loading, are known as Rigid Materials. a- Rich Concrete 1.2cm to 4cm thick layer of Rich Concrete (1:2:4) painted with two coats of hot bitumen is used as horizontal D.P.C.
