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

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

1. Preparation
2. Laying, Ramming, and Compaction
3. Curing
4. Joint Treatment
5. 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.
