It is reality that in a highly populated city like Kolkata, we have exhausted major part of high-ground topography. The city horizon is continuously expanding and low lands are also being used for constructing high rise buildings. In low topography areas there is chance of building soaking in moisture from swamps, ponds etc. There is also the risk of rising high water levels in many parts of the city. Water proofing is especially important in this area where there are chances of ground water soaking into building basements which eventually weakens the whole structure. Waterproofing ensure that moisture does not intrudes into the construction. Proper waterproofing determines the deterioration of concrete structure and maintaining the building strength. Continuous wetting and drying may hamper the quality of structure internally and chipping away of the external surface. In many parts of the city water has high salt content which may hamper concrete structure.
Types of water proofing
It is vital to choose the right kind of waterproofing for optimum results. Choose the kind which suites the local weather of the city and the kind of building for which waterproofing is needed. Detail knowledge about water proofing may help you set the right budget.
• Cementitious Waterproofing
This method is the easiest one. The mixture used for waterproofing is easily available and can be used for indoor waterproofing. This is also used for structures like dams, sewage treatment plans, river locks,
• Liquid waterproofing Membrane Method
Liquid waterproofing is very easy and hassle free method of waterproofing. A very thin layer of primer coat and additional coats are applied to surface which acts as barrier for moisture. The coating used for this type of waterproofing is a type of polymer. The quality of this primer may determine the effect of waterproofing through this method.
• Bituminous waterproofing method
Bituminous coating is another kind of polymer coating which is applied as protective coat. The other name of bituminous coating is asphalt coating. It’s ability to resist water seepage specially from concrete surface makes it one of the widely used waterproofing agent. However, it may not be suitable foe areas which are directly exposed to sunlight; it has a tendency to turn brittle. This method is more suitable for slope roofs.
• Polyurethane Liquid Waterproofing method
It is one of the most durable used for flat roof surfaces. It can be used for weathering and does not get brittle with harsh weather conditions. The other reason for which this method is preferred is that it is highly flexible.
