Liquid-Applied Waterproofing Systems — UAE
Technical guidance on liquid-applied waterproofing systems for commercial and infrastructure projects across Dubai, the UAE and wider GCC — covering both roof refurbishment and below-ground waterproofing applications.
Commercial Context
Liquid-Applied Waterproofing in UAE Commercial Environments
Liquid-applied waterproofing systems represent a technically advanced alternative to conventional sheet membrane waterproofing — forming a seamless, continuously bonded waterproof layer applied directly to the substrate surface. For commercial and infrastructure projects across the UAE, liquid-applied systems offer meaningful technical advantages over sheet-based alternatives, particularly in high-temperature, high-UV environments where membrane continuity and adhesion performance are critical.
Liquid-applied systems eliminate the joints, laps and mechanical fixings that are common failure points in conventional sheet membranes. Applied by spray or roller, they form a monolithic waterproof layer that conforms to substrate geometry, penetrations and complex details — providing uniform waterproof coverage without the vulnerability introduced by traditional sheet-system detailing.
Operational Challenges
Common Project Considerations
- Joint and lap failure in conventional sheet membrane waterproofing systems
- UV and thermal degradation of standard membranes under GCC conditions
- Complex substrate geometry requiring conformable waterproofing coverage
- Large surface areas requiring high-output application methods
- Confined below-ground environments where hot-applied systems are impractical
- Programme efficiency on large commercial and infrastructure projects
- Long-term membrane performance under saline groundwater conditions

Liquid-Applied Waterproofing Across UAE & GCC Project Types
Liquid-applied waterproofing systems are applicable across a broad range of commercial and infrastructure project types common across Dubai and the UAE — from large flat commercial roof surfaces requiring high-output refurbishment, to below-ground foundations and basement structures requiring seamless, hydrostatic-resistant membranes.
Liquid Coatings by Forti Nova supplies two specialist liquid-applied waterproofing systems for GCC markets: SprayGrade for above-ground commercial roof refurbishment applications, and BelowGrade for below-ground waterproofing of foundations, basements, podium decks and buried structures.
Technical Considerations
Technical Guidance
SprayGrade — Above-Ground Liquid-Applied Waterproofing
Water-based two-component spray-applied system for commercial roof refurbishment. UV resistant to ASTM G-155, cold-applied, VOC-free. High-output capability up to 600–800m² per day. 850% elongation. 15-year warranty.
BelowGrade — Below-Ground Liquid-Applied Waterproofing
Two-component spray-applied below-ground waterproofing system. Cold-applied, VOC-free, CE marked, ASTM tested. 850% elongation, recovery >90%, salt resistance >1,200 hours. 25-year warranty.
Seamless Membrane Formation
Both systems form continuous, seamless waterproof membranes — eliminating the joint vulnerability of sheet alternatives and providing uniform waterproof coverage across complex substrates and geometries.
Cold-Applied Methodology
No heat, no flame, no solvents — enabling safe application in a wide range of environments including confined below-ground spaces and operational commercial buildings.

Frequently Asked Questions
Liquid-applied waterproofing involves applying a liquid coating system to a substrate surface, which cures to form a seamless, continuously bonded waterproof membrane. Unlike sheet membrane systems, liquid-applied systems have no joints, laps or mechanical fixings — forming a monolithic waterproof layer across the substrate.
