Basic difference between SBS and APP is that APP-modified bitumen is a “plastic asphalt” and SBS-modified bitumen (Styrene-butadiene-styrene) is an “elastic asphalt.” While its melting point is only slightly lower than that of APP ( Atactic Polypropylene) , it doesn’t have the same flow characteristics as APP-modified bitumen.
When torching APP roofing membranes, the bitumen begins to flow like liquid wax when it reaches temperature 300 F. The molten APP membrane behaves like hot mopping asphalt, and will flow. The ease of melting makes APP bitumen popular on smaller roofs such as residential properties and commercial flat roofs
While SBS has the sticky characteristics at low temperatures and can install with cold adhesive on projects where flames are not permitted. The most suitable application at confined places. This flexibility means it has recovery properties, making it capable of withstanding stresses created by wind, temperature fluctuation and expansion and contraction.
It all depends on the project and the environment associated with it, generally SBS modified bituminous membrane is being applied in low temperature areas whereas APP modified bituminous membrane is preferable to install in hot-melt conditions.
Leakage is a admission of water due to cracks or effect of climatic change on building structures or mechanical damage such as holes in the roof etc
Seepage is to ooze, or pass slowly through pores or other small openings.
Cracks in the roof which develops over the period of time due to any of the following reason incorrect design mix of concrete, rapid drying of concrete (improper curing) or it may be the inadequate strength of the concrete is used.
Pipe penetrations (HVAC, Plumbing) from water and sewer pipes is a common point of entry for water. The reason many of them leak is because they are typically sealed with a temporary patch during the construction of the home.
Lack of slope towards drains leaves scope for water stagnation. One of the chief culprits of water leakage of roof slabs is improper gradient, improper drainage and rainwater collection arrangement.
Clanged drains (plant leaves, dust, etc) blocked pipes may start as minor issues but can quickly escalate into major problems. It can cause slow water drainage, corrosion, flooding, and, in extreme cases, sewage backup and costly repairs.
Wild growth (small wild plants & roots) What began as a dirty roof can quickly lead to larger, more expensive roof problems. Plants can’t grow without moisture. If water isn’t draining off your roof properly, there’s an opportunity for seeds to germinate. When roof drains, scuppers, and gutters are blocked by environmental debris and growing plants, they cannot divert water away and ponding water and/or leaks are likely.
Water Tank over flow, The most common problems include a leak in the float, which means it needs replacing, or a fault with its washers, which will need refitting. Its ignorance may cause seepage/leakage.
Poor tile grouting (Chowka), the tile needs periodic maintenance; cracks can develop in the grout between the tiles, allowing moisture to seep through. To stop the leak and prevent further damage to the underlying plaster or drywall, you’ll need to seal all the places where water can penetrate.
Spall off foam concrete insulation/plaster is caused by poor finishing and the use of water on the surface to aid in the finishing process. To prevent spalling, focus on pouring concrete with just the right amount of water – keep the mix as dry as you can since a lot of water can weaken the concrete.
Lack of Roof Expansion Joint Treatment, This is substantial and poorly designed Expansion Joints lead to leaks and structural cracking
