24-hour artificial rainfall test
No damp appeared on the unexposed face of a 130 mm finished wall with a 40 mm EPS core. Water flow: 35 L/h; overpressure: 6 mm water. IDIEM report 209.637, July 1994; the result is specific to that specimen and test conditions.
Artificial rainfall test (1994) PDF · 0.04 MBSource: Emmedue Panel Specifications, Rev. 05, 01/14, printed pages 8, 9 and 13; and the IDIEM acoustic report dated 21 January 1998. Values apply to the stated assemblies; a lower U-value means less heat transfer. Whole-building results depend on joints, openings and installation.
Specifications and performance references
International comparison reference: 200 mm hollow concrete block + 10 mm cement plaster on each face = 220 mm finished. The uninsulated wall performance is calculated from layer properties published by Bahrain’s Electricity and Water Authority.
R = 0.059 + 0.226 + 0.121 + (2 × 0.010 ÷ 0.75) = 0.4327 m²K/W
U = 1 ÷ R ≈ 2.31 W/m²K
Reduction = (1 − WATAD U ÷ reference U) × 100. An indicative calculation for the stated wall assemblies at equal area and temperature difference, rather than a matched laboratory comparison. The percentage applies to wall heat transfer only, not cooling bills or room-temperature reduction.
Acoustic performance: 45 dB(A) measured gross reduction for the 180 mm finished PSM90 specimen. Installed performance depends on the wall assembly, joints and openings.
Give your design room to take shape
From straight lines to curves and domes. Discuss design possibilities early so your architectural idea connects with buildable details.
Ask about performance. See the evidence.
Your decision needs evidence for the assembly being used. Request technical reports and test conditions, then discuss their relevance with your project consultant.

Design today with tomorrow in mind
Consider insulation, material use and site detailing early. Environmental outcomes depend on the design, construction and operation of the whole building.
Insulation at design stage
Connect envelope choices to building calculations and use conditions.
Material & site coordination
Review quantities, cutting, storage and work routes.
Measure the outcome
Assessment or certification relates to the building and its review; it does not follow automatically from one material.
Expected structural lifespan: more than 50 years
Emmedue states an expected structural lifespan of more than 50 years, provided design, construction and maintenance follow applicable standards and system specifications. Manufacturer statement dated 10 November 2025; this is not a 50-year warranty or an independent test result.

What is the WATAD building system?
WATAD is a panel building system with an EPS insulating core, steel mesh and through-panel connectors. Panels are assembled on site and completed with concrete layers to the project drawings.
Where are WATAD panels manufactured?
WATAD panels use Italian Emmedue technology and are manufactured at the Al Oula Development & Investment factory in Khazaen Economic City, Barka, Oman.
Will the system suit my project?
Start with the location, use, drawings, loads and local requirements. The team and consultant review the intended application and required details.
Can I vary the architectural form?
The family includes curved walls, floors and stairs. Review the concept alongside structural details, openings and connections before construction.
What should a cost comparison include?
Define supply, transport, assembly, concrete, reinforcement, services, finishes, support and programme. Compare equivalent scopes rather than individual material prices.
How do I assess thermal or acoustic performance?
Request the test report and the assembly it covers, then review its relevance to your project. Windows, the roof, details and workmanship affect the whole-building result.
What information should I send first?
Send the location, building use, available drawings, required scope and proposed programme to the team’s official email.
