Hybrid Polyurea Waterproofing

Sunanda Global has been voted amongst the “Top 5 Waterproofing Brands in India” for offering customized waterproofing solutions and has created its brand presence in landmark projects across India.

Sunanda Global’s motto is offering a suitable waterproofing solution based on the customer’s requirements and construction problems.

Sunanda Global provides a wide range of products that covers polymer-modified acrylic coatings, 1K polyurethane waterproofing and sealing membrane (PU membrane), 2K polyurethane waterproofing and sealing membrane (PU membrane), and polyurea coatings, and 2K cementitious elastomeric waterproof coatings range.

Engineers have been demanding high-performance and long-lasting waterproofing materials for basement and superstructure applications according to the structural design requirements for ages.

This outcome is, however, easier to manage if waterproofing solutions are upgraded with appropriate technology products that are suitable for providing long-lasting water snubness and avoiding problems.

Waterproofing materials will be manufactured by modifying the structural design, development practices, and shortage of good quality fine aggregates.

The present structures are more prolonged, and the need for precast & composite structures is increasing. These structures require high-performance waterproofing solutions with more significant elongation and tensile strength.

Due to the changing requirements of the construction, polyurea waterproofing systems, which are very tough but have low resilience, and polyurethane systems, which are flexible but not rigid, have adapted.

These systems have their advantages but simultaneously have restrictions that must be tended to.

Considering the restrictions and catering to present-day specifications, Sunanda Global introduced a hybrid polyurea waterproofing to achieve toughness and resilience.
