What is the Correct & Cost-Effective solution for Terrace Waterproofing?

Every building owner desires the longevity of their project and the satisfaction of its residents. However, leakages from terraces can pose a significant threat to these aspirations. When exploring options for terrace waterproofing, it is crucial to prioritize solutions that can withstand various weather conditions throughout the year.

 

First, let’s delve into the challenges faced.

 

In India, most states and cities endure extreme weather conditions in all seasons, be it the scorching heat of summers, heavy monsoon rains, or temperature drops during winters.

 

Among the building exteriors, terraces and roofs are particularly exposed to these harsh weather conditions. As seasons change, the concrete substrate undergoes thermal expansion and contraction, leading to cracks and water seepage.

 

When waterproofing flat roofs, whether during initial construction or as a retrofit, it is essential to ensure the following:

 

1) Water tightness and resistance to standing water

2) Resistance to weathering

3) Reliability and durability

4) Elasticity and good adhesion to the substrate

5) Resistance to UV radiation

 

For building owners, finding a waterproofing system that fulfills all these requirements is a crucial task.

 

One-component polyurethane liquid membranes offer a comprehensive solution that meets all the aforementioned requirements. These membranes create a continuous and elastic barrier with excellent mechanical strength. They are free from joints or seams and can be used for total sealing of flat roof surfaces as well as local waterproofing of cracks.

 

Polyurethane coating can be applied to various common flat roof substrates, including concrete, cement mortar, and terrazzo. It also simplifies the sealing of challenging areas such as corners, edges, and joints with roof outlets.

 

Polyurethane waterproofing systems provide several advantages, including:

 

1) High elasticity: Cures to form a permanently flexible and resilient barrier for water across a wide range of temperatures.

 

2) Strong adhesion: Exhibits strong adhesion on surfaces such as cement concrete, asbestos, mild steel, and cement-plastered applied surfaces.

 

3) Thermal stability: Irreversible chemical cure prevents melting and flow at high temperatures.

 

4) Tough and abrasion-resistant: Cures to form a durable coating that withstands wear and tear.

 

5) UV radiation resistance: Highly resistant to UV radiation and optimal resistance to external negative impacts.

 

6) Versatile application: Can be applied to any surface.

 

7) Rapid readiness for operation: Minimal waiting time after application.

 

8) High chemical resistance: Withstands exposure to various chemicals.

 

9) Lightweight: Minimal weight after curing, making it suitable for use on lightweight structures.

 

10) Seamless coating: Forms a continuous and seamless coating over large surfaces.

 

11) Long service life: Provides long-lasting protection.

 

12) Easy restoration: Simple and economical restoration as complete removal of the material is not necessary.

 

13) Compatibility with existing waterproofing systems: Can be applied over an existing waterproofing system.

 

“The application and cure times of Polyurethane coatings are fast, reducing downtime, and it is relatively inexpensive and easy to apply.” – Kirk Jeffries, Executive Director, Rhino Linings USA, Inc.

 

Considering the overall performance, appearance, protection, cost-effectiveness, and environmental compliance of polyurethane coatings, they emerge as the ideal choice for terrace waterproofing.
