5 Most Common Types Of Waterproofing In Building Construction |
Posted: May 4, 2017 |
Waterproofing offers protection against moisture which can cause several damages to your your building. There are several ways to waterproof your home depending on where your property is located, the atmospheric conditions and or the part to be waterproofed.
Places where waterproofing can be applied are:
Here are the most common ways of applying waterproofing:
Cementitious waterproofing Cementious is probably the simplest way to waterproof a building and you can get your order for the materials filled within a very short space of time because the materials are available at every mansory store. The entire process ranging mixing materials to the application is quite easy. For the most part, it it doesn't pass through the process of expansion and contraction because it is used in the building interiors not exposed to the sun. Areas cementitious method of waterproofing is used include wash rooms, toilets, showers,etc. Liquid waterproofing It is a tiny coating consisting of typically one primer and two top coats which can be applied via trowel, spray and roller. It is more flexible compared to cementitious method. On the wall, the liquid material will cure into a rubber coating and the coating properties of elongation get to the peak at 280%. How much time the coating will stand is a function of the polymer type used by the manufacturer for making the liquid. It can be done via the spray of liquid membrane made of some modified sort of polymer asphalt. A liquid membrane polyurethane is reserved for roller, trowel, and or spray. Various masonry product manufacturers also deal in polyurethane. Bituminous coating According to the polymerization and formulation of bituminous coating, Bituminous coating, also known as asphalt coating, is used for protective and flexible coating of surfaces. The fiber reinforcement as well as the grade of its polymer determines how much protection and flexibility it will offer against moisture. It is used underneath concretes surfaces such as foundations and terrace... and it offers maximum protection against moisture. However, it cannot withstand the effect of sunlight, hence, it becomes weak and fragile. Bituminous Waterproofing Membrane Method For "send-down-the-rain" kind of roofing or better down-sloped roofing, Bituminous Waterproofing is the perfect type waterproofing method. It torches both self-adhesive membranes and normal membranes. Self-adhesive membranes are compounds made of fillers, asphalts and polymers. In order to improve the adhesive properties, oils and resins are added. Self-adhesive membrane has a very short lifespan- over time the the ability to bind the membranes will reduce. There exist two types of torch membranes: covered and exposed membranes. The exposed can withstand whatever nature will throw at it. Hence it stands more test of time. Experts will only need to prevent the membrane from puncture by adding a screed to the membrane. Polyurethane Liquid Membrane For flat surfaces exposed to weathering whether harsh or mild, this is the most ideal type of waterproofing. However, it is quite expensive. Sensitivity to moisture is very high. Thus before, during and a few days after application, the surface must be moisture free. Moisture can cause the to polyurethane to peel over time. As pointed out earlier the choice will depend greatly on your location and type of construction. It is ideal to get a contractor to survey your environment in order to determine which waterproofing method is ideal for your construction.
