Liquid Roofing And Waterproofing Association
The Liquid Roofing and Waterproofing Association (LRWA) is a UK member organisation of manufacturers of liquid applied coatings for buildings. The association's aim is to educate and inform specifiers, contractors, and the industry as to the properties, correct applications, installation methods, and aftercare of liquid waterproofing systems. History The association was formed in the 1970s and was originally known as the BRCMA (Bituminous Roof Coating Manufacturers Association). The primary purpose of the association was to promote good practice in all areas of the UK bituminous roof coatings industry. The late 1980s and early 1990s saw the rise in popularity of non-bituminous products and in particular liquid roofing. Recognising this trend, the association reinvented itself as ELRA (European Liquid Roofing Association), now focusing solely on liquid roofing systems. The 'European' tag reflected the associations involvement in the drafting of European standards for all areas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liquid Roofing
Liquid roofing is the process of waterproofing a roof by the application of a specialist hydrophobic liquid roof coating. It can be applied to most roof styles, including flat, pitched, and domed ones. History The concept of liquid roofing has existed since the early 1800s, when natural bitumen was combined with jute, straw, rag felt and other man-made materials to provide a waterproofing solution for roofs. In the early 20th century, the manufacture of liquid roof coatings became a commercial activity, with the earliest coatings being based on liquefied rubber. The 1960s and 1970s saw the introduction of acrylics, acrylic emulsions, Styrene-butadiene and unsaturated polyesters, which led to improved quality and durability of the coatings. In 1975, the first water based elastomeric roof coatings were introduced; in the late 1980s, single component moisture-cured polyurethane coatings were developed; they remain the basis of the majority of today's cold liquid applied roof c ...

Waterproofing
Waterproofing is the process of making an object or structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water under specified conditions. Such items may be used in wet environments or underwater to specified depths. ''Water-resistant'' and ''waterproof'' often refer to resistance to penetration of water in its liquid state and possibly under pressure, whereas '' damp proof'' refers to resistance to humidity or dampness. Permeation of water vapour through a material or structure is reported as a moisture vapor transmission rate (MVTR). The hulls of boats and ships were once waterproofed by applying tar or pitch. Modern items may be waterproofed by applying water-repellent coatings or by sealing seams with gaskets or o-rings. Waterproofing is used in reference to building structures (such as basements, decks, or wet areas), watercraft, canvas, clothing (raincoats or waders), electronic devices and paper packa ...

Car Park
A parking lot (American English) or car park ( British English), also known as a car lot, is a cleared area intended for parking vehicles. The term usually refers to an area dedicated only for parking, with a durable or semi-durable surface. In most countries where cars are the dominant mode of transportation, parking lots are a feature of every city and suburban area. Shopping malls, sports stadiums, megachurches and similar venues often have immense parking lots. (See also: multistorey car park) Parking lots tend to be sources of water pollution because of their extensive impervious surfaces, and because most have limited or no facilities to control runoff. Many areas today also require minimum landscaping in parking lots to provide shade and help mitigate the extent to which their paved surfaces contribute to heat islands. Many municipalities require minimum numbers of parking spaces for buildings such as stores (by floor area) and apartment complexes (by numb ...
