According to a renowned waterproofing firm, “80% of building issues arise from roof waterproofing, which is just 2% of the total construction cost. Protect your property with expert roof waterproofing specialist. Covering the rooftop is essential for several reasons: Adequate shelter from weather elements, a safe and comfortable interior, and better aesthetics are some examples. Opt for the best roof waterproofing company in Karachi: Waterproofing Experts.
What is Roof Waterproofing?
Maintaining water-resistant roofs need expertise and acuity. One needs to assess the condition with respect to scratches, crevices, and holes. Dirt and particulates are also important aspects to evaluate. The added layer of protection keeps away heat from penetrating through the top surface. Moreover, it restricts UV and other harmful radiations.
Types of Roof Waterproofing
- Liquid Waterproofing
- Bituminous Waterproofing
- Polyurethane Waterproofing
- Acrylic Waterproofing
- Cementitious Waterproofing
- Sheet Waterproofing
- EPDM Membrane
- Bentonite Waterproofing
- Rubberized Asphalt
Traditional Waterproofing Methods
With the world advancing at a rapid pace, new waterproofing methods are gaining the attention of prospects, especially nanotechnology and self-healing membranes. These processes are costly and more effective than traditional ones. Old-style waterproofing systems include:
- Lime Concrete
- Mud Phuska
- Brick Bat Coba
Lime Concrete Method
Lime Concrete method is preferable for old and new roofs. The material is made from different materials, such as hydrated fat lime, pozzolanic material, and concrete aggregate. All the ingredients are mixed in suitable proportions in water.
Application of Lime Concrete
- Preparation
- Laying, Ramming, and Compaction
- Curing
- Joint Treatment
- Finish
Mud Phuska Treatment
This method consists of painting the surface with hot bitumen and coarse sand. It is preferable for hot areas with a limited budget. The final layer is covered with a mixture of mud and cow dung. Proper curing is essential for a strong water-resistant surface.
Like other methods, this treatment has also evolved with the passage of time. Traditional mud phuska can be transformed into a lightweight material, with the addition of crumb rubber. As the demand for energy-efficient solutions increases, mud phuska treatment is being viewed as a viable and cost-effective method for cooler and eco-friendly roofs.
Application of Mud Phuska
- Preparation
- Laying
- Applying Mud Plaster
- Paving with Brick Tiles
- Curing
Brick Bat Coba Method
A traditional waterproofing technique that enhances the impermeability of flat roofs. This process entails the application of broken bricks mixed with cement mortar on the roof surface. This method has been termed as an ‘effective solution against water seepage’. The gaps between the brick bats are filled with a sand-cement mortar mix, creating a water-repellant layer.
Application of Brick Bats
- Surface Preparation
- Brick Bat Laying
- Finishing Layer
Modern Waterproofing Methods
Contemporary waterproofing techniques offer quicker results, better efficiency, and higher quality. Following are some of the methods:
- APP (Atactic Polypropylene Polymeric) Modified Membrane
- Crystalline Waterproofing
- Nano-Tech Application
- Self-Healing Membranes
APP is a polymer-based water-resistant membrane that is manufactured on high standards. It is a five layered membrane with center core as 20/100-micron polyurethane film that renders protection against moisture ingress. The membrane is available in different thicknesses and height.
Crystalline Waterproofing is a process in which a chemical reaction forms a strong membrane. The crystals react with water and to heal the crevices in concrete, protecting it from steel corrosion and contaminants.
One of the latest technologies on offer, nanotechnology uses nano-sized particles to form a strong waterproof membrane to fix cracks and holes. This membrane is anti-fungal, anti-corrosive, and eco-friendly. It is a recommended method by several professionals, including Waterproofing Experts.
Self-healing membranes entail crack-filling micro-organisms that offer a long-lasting waterproofing coat. Less repairs are required along with a longer service life. It offers a wide range of applications, such as basements and diaphragm walls, tunnels, wastewater treatment plants, and roofs.
