Methods Of Waterproofing in pakistan
Waterproofing in buildings is the formation of an impervious barrier over surfaces of foundations, roofs, walls and other structural members of building to prevent water penetrations through these surfaces. The building surfaces are made water-resistant and sometimes waterproof. Concrete roof Waterproofing in buildings is the formation of an impervious permanent blockage over surfaces of foundations, roofs, walls and other structural members of building to prevent water penetrations through these surfaces. The building surfaces are made water-resistant and sometimes waterproof. Commonly used materials for waterproofing in a building is cementitious material, bituminous material, liquid waterproofing membrane, and polyurethane liquid membrane waterproofing material, injecting chemical waterproofing material etc.unicorn chemical (pvt) Ltd is roof sealing company providing services All over pakistan .unicorn is not only working as material supplier but also providing waterproofing services to our valuable client in multipule city of pakistan .we are best supplier of waterproofing in pakistan .these are methods use for waterproofing in Pakistan .

1. Cementitious Waterproofing Method
Cementitious waterproofing is the easiest method of waterproofing in construction. The materials for cementitious waterproofing is easily available from suppliers of masonry products, and they’re easy to mix and apply.
This method is often used in the internal wet areas such as toilets. This method is usually a rigid or semi-flexible type waterproofing, but since it is used in internal areas such as toilets, it is not exposed to sunlight and weathering. Thus cementitious waterproofing does not go through contract and expansion process.this is very common method has been used for roof waterproofing in pakistan
Applications of Cementitious Waterproofing
Cementitious waterproofing is used in the following type of structures:
- Water Treatment Plants
- Sewage Treatment Plants
- Bridges
- Dams
- Railway & Subway Systems
- Marine Cargo Ports & Docks
- River Locks/Channels & Concrete Dykes
- Parking Structures & Lots
- Tunnels
2. Liquid Waterproofing Membrane Method
Liquid membrane is a thin coating which consists of usually a primer coat and two coats of top coats which are applied by spray, roller, or trowel. It offers more flexibility than the cementitious types of waterproofing in pakistan.
The liquid cures into a rubbery coating on the wall. The elongation properties of the coating can reach as high as 280%. The durability of the waterproofing coating depends on what type of polymer the manufacturer use for the making of the liquid waterproofing in pakistan.
Liquid waterproofing membrane can be of spray-applied liquid membrane composed of polymer-modified asphalt. Polyurethane liquid membranes in separate grades for trowel, roller, or spray are also available from various manufacturers
Liquid waterproofing membrane can be of spray-applied liquid membrane composed of polymer-modified asphalt. Polyurethane liquid membranes in separate grades for trowel, roller, or spray are also available from various manufacturers.PU method is latest technique used for roof waterproofing in pakistan .
3. Bituminous Coating Waterproofing Method
Bituminous coating is a type of coating used for waterproofing and flexible protective coat in accordance with its formulation and polymerization grade. Its flexibility and protection against water can be influenced by the polymer grade as well as reinforcement of fiber.
Bituminous coating is also called as asphalt coating. The most common applications of bituminous coatings include areas that are beneath screed wet. It is an excellent protective coating and waterproofing agent, especially on surfaces such as concrete foundations.
Bituminous coating is made of bitumen based materials and it is not suitable for expose to sunlight. It becomes very brittle and fragile when long exposure to the sunlight unless it is modified with more flexible material such as polyurethane or acrylic based polymers.
The flexibility of the finished products always depends on the solid content of the polymer added to the bitumen.differents grades of bitumen used for concrete roof waterproofing in pakistan
4. Bituminous Membrane Waterproofing Method
Bituminous membrane waterproofing is a popular method used for low-sloped roofs due to their proven performance. Bituminous waterproofing membrane have torch on membrane and self-adhesive membrane
Self-adhesive compounds comprise asphalt, polymers and filler; additionally, certain resins and oils may be added to improve adhesion characteristics. The self-adhesive type has low shelf life as bonding properties of the membrane reduces with time.
Torch on membrane have exposed and covered types. Exposed membrane often has mineral granular aggregate to withstand the wear and tear of the weathering and the other types of membrane, contractor need to apply one protective screed to prevent the puncture of the membrane.membrane sheet is used for indusrtail level for waterproofing in pakistan
5. Polyurethane Liquid Membrane Waterproofing Method
Polyurethane liquid membrane method of waterproofing in pakistan is used for the flat roof area and exposed to weathering. This waterproofing method is expensive.Polyurethane Liquid Membrane can offer higher flexibility. Polyurethane is very sensitive to moisture content present, therefore before application, one has to be very careful evaluating the moisture content of the concrete slab, otherwise peeling or de-bonding of membranes may happen after some time.
