Bitumen waterproofing, also known as asphalt or coal-tar waterproofing, has been around for a long time and is one of the most common and cost-effective ways for waterproofing roofs, basements, and other buildings. To guarantee a long-lasting, leak-free result, locate a trustworthy contractor that utilizes high-quality bitumen and suitable application procedures. Are you ready to learn about bitumen waterproofing in Pakistan? Let’s get started.

What Is Bitumen Waterproofing?

Bitumen waterproofing, commonly referred to as asphalt or coal tar waterproofing, seals and protects surfaces against water damage by using bitumen, a sticky, black, very viscous type of petroleum. Bitumen waterproofing in Pakistan normally comes in two forms: cutback bitumen and oxidized bitumen.

Cutback bitumen employs a solvent to soften the bitumen so it may be applied as a liquid. When the solvent evaporates, it leaves a waterproof bitumen coating behind. Because oxidized bitumen has been chemically treated to stay semi-solid, it is more viscous and requires heating for application.

Bitumen waterproofing is appropriate for concrete surfaces such as flat roofs and basements. It works by generating a thick, continuous, rubbery coating that prevents water from penetrating. Bitumen fills fractures and holes before hardening to produce an impervious barrier.

Clean and prepare the surface before applying bitumen waterproofing, and then apply a primer. The bitumen should then be distributed using a roller, brush, or sprayer. For extra protection, embed a waterproofing membrane or roofing felt in between layers of bitumen. Finally, scatter sand over the top to provide traction.

With proper application, bitumen waterproofing can last 10-30 years. It’s a cost-effective, durable solution and when it’s time for a touch-up, just add another coat! Bitumen waterproofing provides peace of mind that your home or building will stay high and dry.

Key Benefits of Using Bitumen for Concrete Waterproofing

Bitumen use and advantage for waterproofing concrete offers several benefits.

  1. It’s durable. Bitumen can last for decades when properly applied. The thick, tar-like material creates an impenetrable seal that stands up to weather and wear.
  2. It’s flexible. Bitumen can expand and contract as temperatures change without cracking.
  3. It is reasonably priced. Bitumen is one of the most cost-effective waterproofing materials available. Because the raw materials are inexpensive and the application is straightforward, the expenses are kept to a minimum.
  4. It guards against corrosion. Bitumen creates a protective covering on concrete, preventing water and chemical intrusion. This helps to avoid future costly concrete repairs.

Using high-quality bitumen and applying it correctly is critical to getting the most out of this adaptable, low-cost waterproofing option. With the correct product and procedure, bitumen can protect your concrete constructions for many years.

Types of Bitumen Waterproofing Systems Available in Pakistan

There are a few common types of Bitumen waterproofing sheet’s used in Pakistan:

Cold-applied Bitumen

Cold-applied bitumen membranes are easy to apply as they don’t require heating. These pre-made sheets or rolls are adhesive-backed, so you just peel and stick them in place. They’re good for small repairs and patching jobs, as well as full waterproofing projects. The most well-known brands are SikaBit and Polycoat.

Hot-applied Bitumen

Hot-applied bitumen, also known as built-up roofing, uses hot asphalt or coal tar pitch to bond layers of roofing felt or fiberglass and asphalt membranes together. While more labor-intensive to install, hot-applied bitumen is extremely durable and waterproof. It does require special equipment to heat and apply the asphalt. Popular brands are IKO and GAF.

Liquid-applied Bitumen

Liquid bitumen, or asphalt emulsion, is a coating of asphalt droplets in water that you apply with a roller or sprayer. Once dry, it forms a rubbery, waterproof membrane. Liquid bitumen is versatile, bonding well to most surfaces. It has a strong odor during application and takes longer to dry than other methods. Liquid Waterproofing and Texsa are reputable brands.

Bitumen Sheets or Rolls

Pre-made bitumen sheets or rolls, also known as roofing felts or membranes, provide an easy waterproofing solution. The sheets come in a variety of thicknesses, with some reinforced with polyester or fiberglass. You apply them with a torch, hot air welder, or special adhesive to melt and bond the sheets together. Popular brands are IKO and GAF.

How to Apply Bitumen Coating for Concrete in Islamabad and Karachi

To apply bitumen coating for concrete surfaces in Islamabad and Karachi, follow these steps:

Clean the Surface

First, thoroughly clean the concrete surface. Use a wire brush to remove any loose debris or paint. Scrub away dirt and grime with detergent and water. Rinse well with water and allow the surface to dry completely.

Apply Primer (Optional)

For porous concrete, apply a primer like bitumen primer or PVC primer. Let it dry as directed. The primer helps the bitumen coating adhere better to the concrete. For non-porous concrete, priming is not needed.

Heat the Bitumen

Heat bitumen in a double boiler or special bitumen melter according to the product directions. As it heats, stir frequently. Bring it to a temperature between 150 to 170 degrees Celsius so it reaches a brushable or sprayable consistency. Be very careful, as the bitumen and equipment will be extremely hot!

Apply the Coating

You can apply the heated bitumen with a brush, roller, or sprayer. For brushing, use a wide paintbrush. Work in sections across the surface, applying two or three coats to achieve a thickness of at least 2 to 3 millimeters. Allow each coat to dry for two to three hours between applications.
