TERRACE WATER PROOFING.
Terrace waterproofing is the process of applying a waterproof coating or solution to protect the terrace from water damage. It involves identifying the source of water leakage and addressing it before applying the waterproofing solution.
Polyurea Coat:
The polyurea is a synthetic polymer obtained from the reaction of a diamine with a diisocyanate, polymerization reaction is very similar to polyurethane one, but in case of polyurea, resulting link is a “urea”, so it is called polyurea.
By this link we get from generating molecular structure an insensitivity to moisture, thus making the polyurea (if pure) the best waterproof membrane. It is known for its rapid curing time and high strength, making it useful in a variety of industrial and commercial applications, such as construction waterproofing, coatings for truck beds, industrial flooring, and tank linings. Additionally, it can be used as a sealant and insulation material.
Polyurea is a waterproofing material that is often used in industrial and commercial settings to protect surfaces from water damage. It is applied as a liquid coating, which then quickly cures to form a durable, waterproof barrier. This can be used for waterproofing roofs, foundations, decks, and other surfaces. Also used to seal concrete structures, such as swimming pools, water tanks and retaining walls. Polyurea is known for its excellent resistance to water, chemicals, abrasion and impact, which makes it an ideal option for waterproofing surfaces that are exposed to harsh conditions.
We say “pure” because in the market there are numerous polyurea-called “hybrid”, which are a mixture between polyurea and polyurethane. These membranes do not have the same mechanical properties as the pure polyurea.
Poly Urethane Coat:
Polyurethan Waterproofing Membranes show high resistance to standing water, thus it can be used on flat roofs without particularly good slopes. It provides a simple, secure and easy solution to difficult sealing points (e.g. corners, edges, joints with roof outlets, etc.).It creates a continuous, elastic membrane with excellent mechanical strength, without joints or seams, and is used for both total sealing of flat roof surfaces and for local waterproofing of cracks. Discussed below is ts application method
Application Areas:
Flat roofs
Pitched roofs
Balconies
Plaza decks
Patio
Water tanks
In wet damp floor areas from internally and externally
Used to fill the gaps and cracks formed in the walls or floors of buildings such as tunnels, bridges, concrete wall.
Cementitious Coat:
A cementitious coat refers to a type of coating or layering material primarily composed of cement-based compounds. These coatings are commonly used in construction and engineering applications for various purposes, including protection, waterproofing, and aesthetic enhancement.
1. Composition: Cementitious coats typically consist of a mixture of cement, polymers and sometimes additional additives or admixtures to enhance specific properties like adhesion, flexibility, or waterproofing.
2. Application: These coats are applied onto surfaces using various methods including spraying, troweling, or brushing, depending on the specific requirements of the project and the characteristics of the surface being coated.
3. Functions:
– Protection: Cementitious coats provide protection to underlying surfaces from environmental factors such as moisture, chemicals, abrasion, and weathering.
– Waterproofing: They can create a waterproof barrier when applied correctly, preventing water penetration into structures such as basements, foundations, or roofs.
– Repair: Cementitious coats are often used for repairing and restoring damaged concrete structures by covering cracks, spalls, or other defects.
– Aesthetic Enhancement: In addition to their protective functions, these coats can also improve the appearance of surfaces by providing a smooth, uniform finish or by adding decorative elements like color or texture.
4. Properties: The properties of cementitious coats can vary depending on factors such as the composition of the mixture, curing conditions, and application method. Common properties include strength, durability, adhesion, flexibility, and resistance to water and chemicals.
Bituminous Coat:
Bituminous coating, also known as asphalt coating, is a type of protective coating commonly used in various industries for corrosion protection, waterproofing, and sealing applications. It is composed primarily of bitumen, a viscous black liquid derived from petroleum, along with additives such as solvents, polymers, and fillers.
1. Composition: Bituminous coatings typically consist of bitumen as the primary ingredient. Bitumen is a hydrocarbon material that is highly resistant to water and acts as a natural adhesive. Various additives may be included to enhance specific properties of the coating. These additives can include polymers like styrene-butadiene-styrene (SBS) or atactic polypropylene (APP), which improve flexibility and durability, as well as fillers like silica or limestone, which enhance strength and stability.
2. Application: Bituminous coatings are typically applied in a liquid form, either by spraying, brushing, or dipping, depending on the surface and the desired thickness of the coating. The coating can be applied directly to metal, concrete, wood, or other substrates to provide protection against corrosion, moisture ingress, and other environmental factors. Surface preparation, such as cleaning and priming, is crucial to ensure proper adhesion and effectiveness of the coating.
3. Properties:
– Waterproofing: Bituminous coatings form a continuous, impermeable barrier that effectively seals out moisture, making them ideal for waterproofing applications on surfaces such as roofs, foundations, pipelines, and below-grade structures.
– Corrosion Protection: The dense, protective layer formed by bituminous coatings helps to prevent corrosion by shielding the underlying substrate from exposure to corrosive elements such as water, salt, and chemicals.
– Flexibility: Depending on the specific formulation, bituminous coatings can exhibit excellent flexibility, allowing them to accommodate substrate movement and thermal expansion without cracking or delamination.
– UV Resistance: Some bituminous coatings are formulated with UV stabilizers to provide resistance against degradation from prolonged exposure to sunlight.
– Adhesion: Bituminous coatings adhere strongly to a variety of substrates, providing long-lasting protection even in challenging environmental conditions.
4. Applications: Bituminous coatings find wide-ranging applications across industries, including:
– Roofing: Used as a protective layer on roofs to waterproof and extend their lifespan.
– Pipelines: Applied to pipelines for corrosion protection and insulation.
– Marine Structures: Used to protect marine structures such as docks, piers, and seawalls from corrosion and water damage.
– Road Construction: Applied to road surfaces to waterproof and seal asphalt pavements.
– Industrial Equipment: Used to coat tanks, pipes, and other industrial equipment to prevent corrosion and extend service life.
Overlay Costing:
Overlay Coating is ideal for roof waterproofing that is old and needs to be redone. It is a high performance, heavy-duty weightless waterproofing system that can be applied over the existing waterproofing system, without even breaking it. It comes in three different light colors to ensure the customer gets all the three coatings. Newcoat does not require any additional protective system over it and is ideal for flat RCC roofs, even roofs subject to heavy foot traffic. Repairs on the existing terrace surface and the parapets, etc. must be done prior to the coating, as Newcoat is the final system, to give a finish.
