We already know that terrace waterproofing is essential to maintain the condition of a building, increase its life span, and enhance its overall durability. But the question is, what waterproofing solutions are available in the market, their benefits, and limitations?

Terrace waterproofing can be classified into Traditional and Modern methods. Let’s understand them in detail:

Traditional Terrace Waterproofing Methods:

The traditional waterproofing methods have been in use for decades. These methods are generally simple, however, may have distinct characteristics and limitations.

1. Brickbat Coba Method

The Brickbat Coba Waterproofing method involves laying red bricks with gaps between them on the roof. Next, the workers fill these gaps with a dense slurry of cement, and then they douse the roof with water and leave it for at least two weeks to cure. While affordable, this method is effective for a short period.

2. Lime Terrace Treatment

This technique requires a waterproofing mixture by combining lime and molasses. The workers then spray this mix onto a concrete terrace to provide waterproofing. After this process, they leave the roof to cure and regularly water it at specific intervals. It’s important to note that the lime terrace treatment might not last long and needs to be redone frequently.

3. Mud Phuska Waterproofing

The mud phuska method involves using a waterproofing solution made from clay and bhusa sand. The final layer is plastered with a mud-cow-dung mortar, and proper curing is crucial for maintaining its waterproof properties. This technique is best for hot regions with limited funds but may be time-consuming and add stress to the structure.

Modern Terrace Waterproofing Methods:

The latest terrace waterproofing methods incorporate advanced chemicals, products, and technologies to enhance durability and provide superior protection against water damage. These methods aim to safeguard terraces against potential water-related issues by utilizing advanced waterproofing techniques.

1. Liquid-applied Waterproofing

Liquid waterproofing applied as a liquid membrane directly onto a surface is widely used to create a continuous barrier against water infiltration. This method of waterproofing is commonly used on flat roofs.

Liquid waterproofing spreads effectively on uneven surfaces, providing strong adhesion and flexibility to accommodate structural movement.

Types of liquid-applied waterproofing:

• Cementitious: The cementitious waterproofing system consists of cement, sand, and special additives. Plus, they create a strong, rigid, or semi-rigid membrane when applied to surfaces like concrete flat-roof.
• Acrylic: Acrylic waterproofing systems are water-based mixtures with acrylic polymers known for their flexibility, durability, and UV resistance.
• PU (polyurethane): Polyurethane (PU) waterproofing systems are popular for their outstanding flexibility, elongation characteristics, and ability to bridge cracks.
• Hybrid PU (polyurethane): Hybrid waterproofing systems made of PU (polyurethane) combine the advantages of polyurethane and other polymers. These systems show remarkable elasticity, endurance, and resistance to chemicals.
• Bitumen: Bitumen waterproofing systems make use of bitumen, which is a petroleum-derived substance, to produce a dependable waterproof membrane. These systems are resistant to water, flexible, and extremely adhesive.
• Pitch-modified Bitumen: Pitch-modified bitumen waterproofing systems use bitumen as the main material, along with additives like polymers and resins. These systems provide outstanding waterproofing qualities and are highly resilient to soil microbial resistance.
• Epoxy: Epoxy waterproofing systems consist of epoxy resin and curing agents and provide strong, durable, and water and chemical-resistant properties.

2. Sheet-applied Waterproofing

Sheet-applied or membrane waterproofing involves using pre-fabricated membranes attached to a surface using mechanical means, hot-welding, or adhesive.

These membranes are typically made of bitumen, modified bitumen, or synthetic materials like PVC, EPDM, TPO, ECB, and HDPE.

Moreover, sheet-applied waterproofing offers excellent durability and protection against punctures and tears, making it suitable for large roofs, as well as other spaces like basements, retaining walls, decks, and plaza areas.

Types of Membrane Waterproofing:

• Self-adhesive Bituminous Membrane: Providing a simpler and faster application, the self-adhesive bitumen membrane is a popular choice consisting of high-performance SBS polymers. Thanks to its self-healing properties, this membrane ensures long-lasting water resistance for your home.
• Modified Bitumen Membrane: It serves as a highly modified vapor and water barrier, providing high-quality and dependable waterproofing for protecting flat roofs. Modified bitumen membrane offers a durable and cost-effective option.
• Synthetic Membrane Materials: Commonly used in commercial and residential waterproofing, synthetic membranes such as PVC, EPDM (synthetic rubber), TPO (Thermoplastic Polyolefin), etc. are a preferred choice for coating roofs and terraces. Furthermore, they provide excellent insulation to keep your home cooler during extremely hot weather conditions.

3. Integral Waterproofing

Integral waterproofing involves adding chemical admixtures directly into the concrete mix while making. It helps to fill the small pores in the concrete and make it less permeable to water. The waterproofing agent consists of a combination of densifiers, repellents, or crystalline admixtures.

• Densifiers fill the microscopic pores in the concrete matrix to eliminate water infiltration.
• Water repellents make the concrete hydrophobic.
• Crystalline admixtures cause microscopic, water-blocking crystals to seal pores and hairline fractures.

Integral waterproofing becomes a natural part of the concrete, eliminating the need for additional work or expenses. Moreover, it can also make the concrete self-healing and is frequently used for the construction of a new roof, terrace, foundation, etc.
