Below-Ground Waterproofing Systems — UAE
Technical guidance on spray-applied below-ground waterproofing for foundations, basements, podium decks, retaining walls and buried concrete structures across UAE commercial and infrastructure projects.
Commercial Context
The Below-Ground Waterproofing Challenge in UAE Commercial Construction
Below-ground construction is a foundational element of large-scale commercial and infrastructure development across Dubai and the UAE — encompassing basement car parks, podium decks, retaining walls, foundations, buried service infrastructure and tunnels. These elements are exposed throughout their operational life to groundwater, hydrostatic pressure, salts and substrate movement — conditions that demand robust, long-term waterproofing performance.
Failure of below-ground waterproofing is among the most expensive and disruptive structural defects to remediate. The seamless, continuously bonded membrane provided by spray-applied systems eliminates the joint and lap vulnerability inherent in conventional sheet-based alternatives — providing uniform protection across complex below-ground geometries.
Operational Challenges
Common Project Considerations
- Hydrostatic pressure from groundwater on basement and buried structures
- Elevated salt concentrations in GCC groundwater from coastal proximity
- Substrate movement and thermal cycling in large concrete structures
- Joint vulnerability in conventional sheet membrane systems
- Confined below-ground access affecting application method selection
- Programme continuity on large-scale UAE commercial and infrastructure projects
- Complex geometry around penetrations, tie rods and structural transitions

Below-Ground Waterproofing Across UAE Commercial & Infrastructure Projects
Large-scale commercial development across Dubai — mixed-use towers, retail and hospitality podiums, logistics complexes and infrastructure projects — routinely involves extensive below-ground construction. Basement car parks, podium decks, retaining walls and buried utility infrastructure are standard elements of major UAE commercial developments.
GCC groundwater conditions frequently involve elevated salt concentrations — particularly in coastal and reclaimed land areas prevalent across Dubai's development zones. BelowGrade's salt resistance performance (>1,200 hours) and 850% elongation make it well-positioned for below-ground waterproofing applications across these environments.
Technical Considerations
Technical Guidance
Spray-Applied Seamless Membrane
BelowGrade forms a continuous seamless waterproof membrane with no joints, laps or mechanical fixings — eliminating the primary failure points of conventional sheet systems across complex below-ground geometries.
Cold-Applied, VOC-Free
No heat, flame or solvents required — making BelowGrade practical and safe for confined below-ground environments including basements, service ducts and enclosed underground structures.
Rapid Cure
Touch-dry within approximately 1 minute at 20°C. Additional protection or insulation can typically be applied around 20 minutes after application — supporting programme efficiency on large-scale projects.
Membrane Performance
850% elongation, recovery above 90%, salt resistance >1,200 hours, air permeability 0.0004 L/(s.m²) at 75 Pa — with CE marking and ASTM testing.
Commercial Considerations
Commercial Guidance
Coverage and Programme
BelowGrade spray application is capable of 600m²+ daily output depending on project conditions — supporting large-scale below-ground waterproofing programmes on major commercial and infrastructure projects.
Membrane Thickness
1.35 kg/m² for approximately 1mm (airtight membrane) and 2.7 kg/m² for approximately 2mm (watertight membrane). Thickness selection based on hydrostatic pressure and project requirements.
Warranty
BelowGrade carries a 25-year product warranty subject to correct application and project conditions.
