What is the Best Waterproofing Process for Concrete Slabs?

With a redefined urban vision, India is rethinking the future of its residential and commercial properties and focusing on making them more energy-efficient and sustainable in the long run. While traditionally defined by historical and cultural influences, today, the country has adapted contemporary architecture and is rapidly paving the way for hyper-urbanization.

As you are aware, incorporating a new and revitalized urban landscape comes with its own set of challenges. Right from the start - conceptualisation and planning to execution - there are specific requirements that need to be met to protect the structural integrity and add life years to the establishment.

In new construction projects, a streamlined operation that improves efficiency is key, and choosing the correct waterproofing process will enhance its overall development. Collaborating with pioneers and experts from the industry, who provide the best waterproofing solutions, like Dr. Fixit, is the need of the hour.
 

What to keep in mind?

In our country, the construction of most roofs involves the usage of reinforced cement concrete or concrete slabs. Over years, these structures show signs of deterioration of matrix and corrosion of steel bars. Therefore, be it in residential or commercial spaces, roof waterproofing is of utmost importance when it comes to designing and executing damp-free and leak-proof structures.
 

What is roof waterproofing?

Roof waterproofing is the process of applying an impermeable material layer to concrete slabs to stop moisture from entering and making the building waterproof, allowing it to withstand constant exposure to damage and degradation.

Concrete slabs are permeable and pervious - they absorb moisture, waterborne toxins, and compounds that weaken the structure and cause health hazards. Moisture will penetrate via the capillary route generated by the osmotic effect if surplus water is not correctly swept out during the casting of concrete slabs. If it is not effectively cleared off, fine pores will be formed in the roof slab and each of them will be linked to one another.

The concrete roof slab system is also known as a flexural member. This system is weak under tension and can develop fissures and cavities as a result of thermal contraction, expansion and shrinking. Water will infiltrate through the gaps and pores as a direct consequence. One of the easiest and most efficient ways to seal the concrete slabs is by using Dr. Fixit waterproofing solutions with a diverse range of applicability for new constructions, and repairs and renovations.

What is the importance of roof waterproofing?

Over time, close observation of construction projects shows that roofs are commonly made of concrete slabs and they are subjected to external exposure at all times. Due to constant exposure to water, air and heat, thanks to the climatic conditions, the concrete slabs are subjected to cracks, moisture retention, and expansion. Therefore, the roof waterproofing process should be done gradually with precision.

As you are aware, concrete slabs are porous and retain water, waterborne pollutants, and chemicals. Due to the construction material’s property, it is essential to invest in a permanent roof waterproofing system if you want to safeguard your concrete and guarantee its longevity, retain your establishment’s quality, and structural integrity as well. Waterproofing minimizes the absorption of moisture which further prevents the formation of crevices or cracks on the structure.

Keep the following things in mind when choosing a roof waterproofing product: durability, bonding strength, drying time, UV resistance, and a good brand reputation.

Benefits of concrete slabs’ waterproofing process

• Improves durability and longevity of your establishment
• Keeps structural integrity intact
• Keeps surfaces damp-free and leak proof
• Cost-effective in the long run
• Energy-efficient and sustainable solutions
• Prevents health risks caused by mould and mildew
   

Best waterproofing solutions for you

With myriad options and techniques available in the market, you should choose the best waterproofing process based on the site's state and application capabilities.

Some of the traditional terrace or roof waterproofing treatments include Cementitious waterproofing, Liquid waterproofing, Bituminous layering and Crystalline admixtures.

However, foreseeing contemporary roof waterproofing requirements, Pidilite has developed and launched various technologically advanced products and treatment methodologies on positive and negative sides of surfaces, for residential and commercial properties in the country.

Energy-efficient process

Dr. Fixit LEC (Low Energy Consumption) systems is a synthesis of insulation and waterproofing solution for roofs. This process reduces heat gain through concrete slabs by more than 90%. It minimizes cracks and fissures on the surfaces by protecting them from thermal stresses, thereby making your building 100% leak-free. Additionally, it saves energy consumed by air conditioners.

Polyurethane Waterproofing Treatment

The PU system is a two-component UV resistant and modified polyurethane liquid that can be applied on a prepared surface with ease. This coating has exceptional crack-bridging properties, flexibility and durability, excellent bonding with concrete and construction materials. It also renders the substrate breathable, water-resistant, and weatherproof.

Pidilite developed products like Dr. Fixit PU Foam Injection, Dr. Fixit PU Plain Injection and Dr. Fixit Novolac Clear among others can be used for waterproofing concrete slabs on the roofs, floors, and basements of residential and commercial properties.

Hybrid Polyurea Waterproofing and Coating System

The Hybrid Polyurea System constitutes a more recent and advanced waterproofing technology than the traditional ones used in protective coating applications. It is based on the reaction of an isocyanate component with an amine blend. As the reaction is rapid, within seconds, it requires specialized personnel and equipment to mix and apply this waterproofing methodology.

This system ensures ultra-fast curing of coating, chemical resistance, insensitivity to humidity during the application, thermal stability to temperature variation and good adhesion to substrates.

For this method, products from Pidilite’s Dr. Fixit can be used. Some of them include Dr. Fixit Hydrolastic PU, Dr. Fixit PU Roofkote and Dr.Fixit Newcoat PU Cool among other waterproofing commodities available.

In conclusion, as the structural strength of your residential and commercial properties are highly dependent on effective waterproofing solutions for your roofs, exterior and interior walls, and basements etc., it is advised to consult experts in the field. Click here to get in touch with an expert from Dr. Fixit.
