Bitumen, produced through the distillation process, is an effective medium for waterproofing surfaces. It is used in construction projects, namely roads, highways, buildings, and more.
Historically, bitumen was used for waterproofing substances in Syria, approximately 40,000 years ago. Apart from that, it was applied as a sealant or adhesive. Some sources discovered bitumen in areas of Mohenjo-Daro and Mehrgarh. Residents of the ancient Middle East, called Sumerians, used bitumen for several construction projects, including bricklaying, caulking, and waterproofing ships.
What are Bituminous Paints?
Bituminous paints are made from coal tar dissolved in naphtha or mineral spirit. These solutions are applied in a liquid or semi-liquid form, modified with other materials, such as acrylic-based polymers or polyurethane to increase flexibility and sturdiness.
Since bitumen is insoluble in water, its coating is effective against moisture ingress, seepage, and other water-related issues. Furthermore, it restricts air movement from contacting the substrate’s surface, keeping away corrosion and ultra-violet degradation.
Bituminous paints are a feasible solution for coating leak-prone surfaces, especially terraces, roofs, and foundations. In addition, they can enhance the life of metals. Bituminous coatings are also applied on stairways, railings, fences, and other structures.
Can we use Bitumen Coating/Membrane?
Bituminous membrane is specially used to seal low-slope roofs. Experts from Lakhwa Chemical Services are experienced in applying the membrane on different surfaces like concrete. They are well-versed with the prerequisites and safety measures needed for a perfect finish. As the process involves the use of flame torches and fire equipment, it’s essential to wear gloves, goggles, and rubber shoes. The membranes are composed of additives that modify properties. To bind them to the surface, the bitumen sheets are heated by a flame torch.
Modified Bitumen – An Innovative Step in the Waterproofing Industry
Over the years, waterproofing solutions have taken a new course in terms of better quality and performance. Modified bitumen is an example. Its durability, tensile strength, and simple installation has amplified sales and use throughout the world, including Pakistan.
Modified bitumen is purchased in membrane forms installed directly onto the substrate through an adhesive. The material is attached to the substrate with three methods:
Types of Modified Bitumen Membranes
Typically, there are two types of modified bitumen membranes:
Also called plastic asphalt, APP membranes consists of asphalt mixed with plastic-based polymers under high temperatures. This membrane is resistant to UV radiation. In addition, it is one of the best options for cooling your home’s interior.
SBS membranes are made with polyethylene, polyester felt, and fiberglass. These membranes are produced in different ways: Some are covered with polyethylene on both sides while others involve the use of silica sand, slate chippings, or aluminum foil on one side and polyethylene on the other.
Styrene-butadiene-styrene membranes are used on different surfaces and areas, such as basements, foundations, terrace roofs, water tanks, retaining walls, and restrooms.
Why is Bitumen Popular in the Waterproofing Industry?
Bitumen is one of the best waterproofing products for several reasons. Firstly, it is widely accessible in form of liquid. Connect with professionals from Lakhwa Chemical Services for a free trial.
Besides paint, bitumen is also used in the form of sheets, a safer and eco-friendly alternative. In addition, it is easy to apply and maintain. Bitumen is long-lasting and reusable, helping to conserve money and time for the user. Lastly, it reduces noise pollution.
Bitumen Grades – Types and Uses
There are numerous types of bitumen grades that define the material’s quality. Some of them are:
Viscosity-grade bitumen depends on the product’s toughness. The higher the grade, the stiffer the bitumen. Some of its types are:
- VG 10
- VG 30
- VG 40
This bitumen type is based on performance at specific temperatures. Following are some of the categories:
Other Bitumen Grades
Besides the above-mentioned grades, others include:
- AH Grade Bitumen
- Emulsion Bitumen
- AC Grade
- Cutback Bitumen
- Oxidized Bitumen
Bitumen is essential for many reasons: It is used for roads, waterproofing surfaces, preserving timber, and more. It is available in plastic, emulsion, straight-run, blown, cutback, and other types.
Statistically, the global bitumen membrane market is valued at USD 2.5 billion in 2018. Moreover, it is likely to grow at a CAGR of 5% till 2025. According to usage, the bitumen market is segregated into residential and non-residential. Non-residential leads the market, due to the extensive use of bitumen in renovation projects, educational institutions, hospitals, and other sectors. It has a staggering share of more than 50%.
