The Retal Rise and Nobu Hotel Towers: A New Era of Luxury in Al-Khobar

Off the coast of the Persian Gulf lies Al-Khobar, a vibrant coastal city that has taken luxury living to new heights. Recently completed in 2025, the Retal Rise Tower along the city's Corniche has become a landmark in urban development, harmoniously blending modern architecture with natural beauty. This impressive luxury complex features two distinct towers—the Retal Rise residential tower and the Nobu Hotel, both designed to offer premium living experiences.

A Unique Location

Al-Khobar, home to around 410,000 residents, offers not only a bustling urban landscape but also a scenic shoreline for residents and visitors. The Corniche Road stretches along Half Moon Bay, making it a popular destination for leisurely strolls, dining, and beach activities. The towering edifice of the Retal Rise adjacent to the Corniche engages both tourists and locals alike, providing them with an exquisite view.

Towering Developments

The development consists of a sleek 25-story residential tower housing 129 luxury apartments alongside a 16-story tower dedicated to the famed Nobu Hotel. This exquisite hotel includes 101 sophisticated rooms and 62 Nobu Residences, enriched by the renowned Nobu Restaurant and a chic café, setting a new standard of hospitality in the region. The ambiance is further complemented by views of the coastal landscape, merging the inside luxury with the breathtaking outside scenery.

Innovative Construction Solutions

To secure structural integrity and ensure longevity, developers opted for the Penetron system—an advanced concrete waterproofing solution that tackles environmental challenges head-on. The choice of Penetron was crucial for providing watertight security for both the raft foundations and retaining walls necessary for such a graceful yet massive structure.

Key Features of the Penetron System

1. PENETRON ADMIX: This crystalline waterproofing admixture, responsible for fortifying the concrete mix, was incorporated at a dosage of 1% of cement weight to treat approximately 8,000 m³ of concrete. This enhances the concrete's resistance to water infiltration.

2. PENEBAR SW-45 Waterstops: Installed throughout construction and cold joints, these swellable waterstops create an active barrier that expands in contact with water, rendering jointed areas impermeable.

3. Topical Application of PENETRON: For added security, PENETRON—a specialized topical crystalline waterproofing material—was applied to sections of the retaining walls to buffer them against hydrostatic pressures and aggressive groundwater.

4. PENECRETE MORTAR: This waterproofing mortar was utilized to mend small cracks, voids, and imperfections within the raft foundation and retaining walls, ensuring any surface irregularities were efficiently addressed.

Sam Annous, Managing Director of Penetron Saudi Arabia, expressed satisfaction with the project's success, emphasizing the team's local support and quick response, leading to exceptional customer satisfaction.

The Mark of Quality and Sustainability

The Retal Rise and Nobu Hotel Towers aren't just buildings; they're a testament to innovative construction practices, luxurious living, and sustainability in urban development. The incorporation of Penetron's state-of-the-art waterproofing technology plays a pivotal role in ensuring that these towers withstand the test of time and the elements, thus preserving their allure and functionality for years to come.

As Al-Khobar continues to evolve, developments like Retal Rise and Nobu Hotel symbolize the city’s forward momentum in embracing innovation while maintaining a commitment to luxury.
