The uppermost part of a building or a house is the roof. The roof shields the entire structures from all types of external factors (i.e., rain, dust, wind. Sunlight etc) and provides a complete shape to the structure. The roof generally divides into three broad categories: 1. flat roof; 2. pitched roof, and 3. shells and folded plates. As per Scottish Technical Handbook flat roofs are, “the slope of which does not surpass 100 from horizontal”. The mode of construction of flat roof involves one of the following; reinforced concrete, reinforced brick work, precast concrete roof, and waffle units.
Mostly the roof
Mostly the roof is one of most neglected components of a house. Because it is hard to reach and out of sight. Because most roof sealers deteriorate within a couple of year. Regular maintenance and inspections are mandatory to inspect any leakage from the roof. As roofs constructed from reinforced concrete are mostly porous and holds moistures. Thus, moisture or water leakage. Flows from top floor to ground floor through walls and ceilings. And result in the commencement. of one or more of the following problems:
Dampness on wall
Peeling of paint and plaster from the wall
Growth of fungus leading to unhygienic condition and onset of diseases
Ingress of water into wall causing electric short circuiting
In order to prevent the leakage and dampness of roof, waterproofing the roof is the most promising technique for maintaining your roof in good condition. But it gets more difficult when dealing with a flat roof. Unlike sloping roofs, which enable water to easily slide off, flat roofs have a relatively shallow slope and so accumulate dust particles, and other debris, which may hinder the roof from draining water from the exterior of structure, as required.
The waterproofing material laid on the roof requires substantial focus because it is subject to an accelerated degradation procedure; however, its key role is to develop resistance against water in the entire structure and particularly in the roof section. In addition, the waterproofing material should also resist certain factors such as;
Expansion or shrinkage
In this context, there is a need for a thorough research and assessment of the suitable waterproofing design, construction technology, and maintenance procedures from the design stage to prevent any waterproofing flaws during the roof treatment. Furthermore, an analysis of environmental factors, as well as of the various failure factors during construction, base on field cases, is require for selecting a most appropriate waterproofing or sealing method that can withstand the environmental conditions over an extend period of time.
The proper design
The proper design of the flat roof’s falls is essential to the roof’s overall drainage. A roof should be provided proper channels that prevent any water stagnation and allow flow of water away from the roof towards suitable drainage points. Surface water must be remove off the flat roof as soon as possible to avoid accumulation of water on the roof surface. Because of temperature variations between the wet and dry roof sections, a differential thermal movement may be initiate which is a major source of roof deterioration.
Zavza Seal is an experience general contracting business that is driven by a desire to exceed expectations.
Zavza seal is proud to introduce Basecrete, a waterproof bond coat with unmatched adhesive characteristics. This adhesive can be applay directly on the roof without any primer or bond coat and provide a long-lasting insulation to any leakage or water dampness.
Basecrete can be appli on the substrate by trowel, roller (3/4”), brush or by spray. It can be applied on the surface in two layers, i.e., one vertical and one horizontal. After the first layer successfully passed the thumbnail test, the second layer should be laid over it.
In addition to Basecrete, Zavza Seal also offers its new state of the art waterproofing products: APMC and COAST.
Our goal is to design a product as per the requirement of the client and waterproof the flat roof. We ensure that your flat roof will be leak-free for many years to come.
