As mentioned above due to the good adhesion of bitumen membranes, the reinforcement of the fiber layers and the appearance of sheets, the bitumen film is often used to waterproof large areas. with high temperature, friction, abrasion resistance and impact resistance such as: Waterproofing toilets, bathrooms, terraces, flat roofs, plants, basements, foundations, etc.

Prepare construction surface:

The surface must be hard, clean, dry and free from contamination
Create a flat surface, sealing gaps and holes by machine or by hand
Construction of hot torch type:
Spread the bitumen sheet onto the surface and apply as required and follow the manufacturer's instructions. Can be laminated ..
When applying, ensure that the correct surface has been marked
Dry the film, heat up the surface area of ​​the construction, then paste the dried film into this area, need to work quickly and evenly for the bitumen layer to stick very well (this is the most important part - the unprofessional can hardly do well)
Overcome bubbles bubbles by puncturing the membrane with a sharp knife. Although this hole will be self-sealed, during construction, it is recommended to avoid the above roof.
Construction for horizontal surface first. then vertical construction, Must overlap in accordance with the requirements of the material.
Dry paste waterproof membrane, warehouse
Material preservation:
To vertical avoid stamping

Bitumen or bitumen is a substance commonly used in waterproofing technology. It is present in many waterproofing products on the market today.

Many people think Bi tum is asphalt. But the reality is not so. Asphalt is only a branch of Bi tum. Bium is defined by British standards:


A viscous or solid liquid compound containing hydrocarbons and their derivatives that can dissolve in tricholol ethylene. black, with adhesive properties and waterproof. Biomass is obtained from refining and is also found in nature in the form of a combination of minerals

The classification of Bi Tum is very complicated due to the many sources that make it up. Asphalt and tar are one of the variants of bitumen.

In which asphalt is separated from oil by technology without breaking the structure (crackinh) or changed by heat and pitch is the common word used to spend the liquid obtained when distillation decomposes or carbon. chemistry of natural organic materials like coal or wood in a rare gas condition.

Bitumen is a substance used very popular in waterproofing technology. It is present in many waterproofing products on the market today. Many people think Bitumen is asphalt, but it is not. Asphalt is only a branch of Bitum.

By British standard: Bitumen is a viscous or solid liquid compound, containing carbon hydrates and their derivatives, can dissolve in tricholene-ethylene, stable, almost non-volatile and softened when heated. Bitumen is brown or black, with adhesive properties and waterproof. Bitumen is obtained from refining and is found in nature as a combination of minerals.

The bituminous classification is very complicated due to many origins. Asphalt and tar are one of Bitum's variants. Asphalt is separated from petroleum by technology without breaking the structure or being changed by heat while tar is a liquid obtained by distillation of hydrolysis or carbonization of natural organic materials such as coal. or wood in rare gas conditions. Due to Bitum's inbuilt waterproofing properties, most waterproofing products use it in their composition. Manufacturers only reinforce layers of fiber, mesh ... to enhance flexibility, toughness, elasticity, mechanical impact resistance for Bitum-based waterproof membranes. Oil paper is the picture
Bitumen membranes have good adhesion, are reinforced with fiber layers and have the shape of sheets, so bitumen membranes are often used to waterproof large areas, withstand high temperatures, friction, abrasion resistance and impact resistance such as waterproofing terrace, flat roofs, basements, foundations ...

Applications of Liquid Waterproofing Membrane

Applications of Liquid Waterproofing Membrane

  June 01, 2020

In many countries such as US, UK, this waterproofing membrane is applied on exterior walls also. It is available in different colors so that it matches the color of wall. Approx. 5 gallons of waterproofing membrane can be used for 325 sq. meter of concrete surface. You need to put 1 coat, let it dry and then put the second coat.

It can also be applied on concrete bridges (It can have an application rate of 800 sq.meter per hour). Concrete expands and shrinks causing cracks under high or low temperature causing water seepage, the liquid waterproofing membrane has UV absorption properties and thus it saves damage to concrete in such conditions.

The liquid waterproofing membrane can also be applied on metal deck steel bridges which have space age joint system. It prevents the seepage from the joints. It increases the longevity of the bridge and this comes into picture when the bridge is rebuilt after 10-15 years.



The liquid waterproofing membrane not only prevents the cracks but also prevents the corrosion of inner materials, the steel bars, and the joints. It seals the cracks up to 1.3 mm width and can withstand expansion up to 0.4 mm and what more the bridge is ready to use for traffic in less than 6 hours.
Surface preparation for Applying Liquid Waterproofing Membrane
The surface to be waterproofed should be clear from dirt, dry and clean. There should not be any loose patches on the surface so the contractor needs to ensure proper surface preparation prior to application.

Curing of Liquid Waterproofing Membrane

It is critical that the applied membrane should be watered soon after the membrane is touch dry. As per standard specs it has to be cured by water following couple of days.
Low Maintenance

It gives a low maintenance service long life. It’s a lifetime smart alternative then other conventional methods. If the bridge last for 200 years so as the waterproofing work too.

It also saves the cost of filler and sealers and other materials which will be used in future to repair cracks and still remains a temporary solution only.

Liquid waterproofing membrane is available in the form of liquid and is sprayed or applied by brush or roller to the concrete surface which forms a thick joint free membrane in contact with air.


Benefits of Liquid Waterproofing Membrane over other conventional methods

The benefits of this process lies in its simplicity to apply. The joint free process is the most important benefit as there is significantly no chances of seepage of water unlike in roll sheet WPM and other water proofing methods. The contractor can cover larger area in a day and if applied next day can start overlapping the layer finished last day with spray liquid waterproofing membrane.



The membrane thus formed should be proper thickness as thinner membrane can break down, care has to be taken by installer and engineer in charge.
Features of Liquid Applied Waterproofing Membrane

These liquid applied systems feature coatings have elongation properties, durability, flexibility, abrasion, chemical resistance providing successful installation. The liquid waterproofing membrane provides optimized performance and also most importantly longevity.

Thus this method of waterproofing is time saving process and also no need to shut down the other works as if applied in morning gets dry and strong till afternoon. It saves a lot of labor cost, and gives maximum quality results.

While sheets and other membranes degrade over time, liquid applied waterproofing provides a long lasting effects. When applied over concrete surface it fills the cracks of the concrete creating a protective vapor barrier system, penetrates in concrete up to a depth of 20 mm and maintains a water tight seal, thus increasing the strength of concrete.
