Spray Applied Polyurea Waterproofing
Spray applied polyurea waterproofing is an advanced, high-performance solution that creates a seamless, monolithic, and highly durable barrier against water, chemicals, and mechanical damage, making it an ideal choice for concrete, metal, and geotextile surfaces. Unlike traditional waterproofing methods such as bituminous sheets, cementitious coatings, or polyurethane membranes, polyurea is a fast-curing, flexible, and highly resilient material that offers superior protection in harsh environments.
Polyurea coatings must comply with ASTM standards for durability. Additionally, polyurea is known for its high chemical resistance, making it an excellent choice for waterproofing areas exposed to acids, alkalis, fuels, and industrial chemicals, such as oil refineries, wastewater treatment plants, and chemical storage tanks.
Product Description
Spray applied polyurea waterproofing’s ability to cure within seconds to minutes allows for rapid installation, significantly reducing downtime and enabling structures to be put back into service quickly, making it particularly useful for bridges, tunnels, basements, parking decks, industrial flooring, and secondary containment applications. One of the key advantages of Spray applied polyurea waterproofing is its outstanding flexibility and elongation, which allows it to bridge cracks and withstand structural movements, preventing failures caused by substrate shifts or temperature fluctuations.

-
Armourtuff P2119, Spray Applied Polyurea based Waterproofing Coating
ARMOURTUFF® P2119 is a spray-applied polyurea waterproofing coating with fast-curing properties, offering exceptional mechanical, chemical, thermal, and weather resistance. It forms a uniform, elastic, seamless waterproof membrane that bonds well to substrates like concrete, steel, and various waterproofing layers. Its versatility allows for application on irregular surfaces, making it ideal for green roofs, flower beds, and more. With medium elongation and the ability to bridge cracks up to 2mm, it ensures long-term crack resistance, superior freeze/thaw resistance, and minimal shrinkage. This coating is commonly used in concrete basements, wastewater treatment plants, bridge piers, parking floors, and terrace gardens, where durable and flexible waterproofing is required.
