Bascrete Waterproofing of Flat Roofs

Waterproofing of a flat roof is determinative as to the uppermost part of a building, along with a house is a roof. It shields the entire structure from all types of external factors (i.e., rain, dust, wind, sunlight etc.) and provides a complete shape to the construction. 

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 on a flat roof involving one of the following points. Reinforced concrete, reinforced brickwork, precast concrete roof and waffle units. Mostly the roof is one of the 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 years, 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. 

Therefore the wetness and water leakage move forward from the top floor to the ground floor through walls and ceilings. As a result in the commencement of one or more of the following problems: Dampness on wall water dripping feeling of paint and plaster from the wall growth of fungus leading to unhygienic condition and onset of disease ingress of water into the wall causing electric short-circuiting To prevent the leakage and dampness of the roof, waterproofing the roof is the most promising technique for maintaining your roof in good condition. But it gets more back-breaking when dealing with a flat roof. Unlike sloping roofs, which enable water to smoothly downswing smooth roofs have relatively shallow slope sand so, which accumulate dust particles, and other debris, which may hinder the roof from draining water from the exterior of the pile, as required. The waterproofing material laid on the roof requires substantial focus. It’s subject to an accelerated degradation procedure. Although, its essential role is to develop resistance against water in the entire structure along with immensely in the roof section. 

In addition, the waterproofing material should also resist certain factors. Such as 

  • Atmospheric factor 
  • Temperature fluctuation 
  • UV-rays. 
  • Movements 
  • Expansion or shrinkage 
  • structural elements 

In this context, there is a need for 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. Based on field cases, require for selecting the most appropriate waterproofing or sealing method that can withstand the environmental conditions over an extended time. The proper design of the flat roof’s falls is essential to the roof’s overall drainage. A roof should provide proper channels that prevent any water stagnation and allow the fluxive away from the roof towards suitable drainage points. The water surface must remove from the flat roof as soon as possible to avoid the accumulation of water on the roof surface. Because of temperature variations between the wet and dry roof sections, a differential thermal movement may initiate which is a major source of roof deterioration.
