Jeddah Hotel Rooftop Pool Built to Last with Penetron System

The Hilton Garden Inn in Jeddah, Saudi Arabia, was officially unveiled in late 2026, adding another notable luxury hospitality destination to the popular Red Sea resort. The Penetron System of crystalline concrete waterproofing products was specified to provide a durable waterproofing solution for the hotel's key concrete structures.

ORLANDO, Fla., Oct. 14, 2026 /PRNewswire/ -- "A rooftop swimming pool on a luxury hotel presents potentially serious design and performance risks, with hydrostatic loading on an elevated structural slab and guest rooms below exposed to any leakage," points out Sam Annous, Director and Partner of Penetron Middle East.

While a traditional membrane system can offer installation speed, any membrane breach over the service life of the pool risks staining and damage to ceilings, walls, and guest rooms below.

"The project brief for the Hilton Garden Inn was to protect the below-grade concrete structures and deliver a pool that remains watertight for the life of the building without relying on a surface membrane system," adds Sam Annous.

The Penetron Middle East team specified an integral waterproofing approach using three Penetron systems working together:

• PENETRON ADMIX, dosed at the batching plant, transforms structural concrete into a self-healing, waterproof matrix that resists chloride ingress, carbonation, and chemical attack.
• PENEBAR SW45 swellable waterstop strips, combined with PENEBAR PRIMER, seal every construction joint and penetration, which are typically the weakest points in any water-retaining and below-grade structure.
• PENETRON slurry and PENECRETE MORTAR are used to address localized cracks and tie holes and to finish any visible defects.

Once exposed to moisture, PENETRON ADMIX reacts with calcium hydroxide and water to form insoluble crystalline structures within the concrete, sealing capillaries and static cracks up to 0.5 mm and reactivating when new moisture appears. The resulting resistance to hydrostatic pressure means the matrix itself becomes waterproof, with no surface layer to puncture, peel, or age out.

After commissioning, the pool was filled and held for testing. The walls of the floor below were found to be almost entirely dry, with no water leakage detected beneath the slab. PENETRON ADMIX performed as a standalone waterproofing system, with no membrane required.

"The Hilton Garden Inn in Jeddah is the latest Hilton Hotel project to specify the Penetron System," adds Sam Annous. "Our integral crystalline waterproofing solution continues to enjoy growing success across the region."
