PENETRON ADMIX

Orlando – October 16, 2026 -- A crystalline waterproofing admixture removed roughly 60 days of planned waterproofing work from the rehabilitation of the Dujmovača Tunnel in Split, Croatia, and cut water penetration depth by 83% after ten test cycles, according to Penetron Group.

Redesign followed material shortage and failed adhesion tests

The Dujmovača Tunnel (M604) is part of the Split suburban railway line and is one of two railway tunnels beneath the city center. The rehabilitation targeted waterproofing and drainage to control water ingress. The original design specified a dimpled membrane system to channel inflows through drains and half-pipes into a drainage channel.

Two problems forced a rethink. The specified composite drainage material was no longer available, and shotcrete adhesion tests returned values below the required threshold, said Theodor Mentzikofakis, Managing Director and Partner of Penetron Hellas.

Jeddah – October 14, 2026 -- The rooftop pool at the Hilton Garden Inn in Jeddah, Saudi Arabia, passed post-commissioning testing with walls on the floor below found almost entirely dry and no leakage detected beneath the slab, according to The Penetron Group. PENETRON ADMIX performed as a standalone waterproofing system, with no membrane required.

Penetron Middle East specified three integrated systems for the pool structure

The brief called for protecting the below-grade concrete structures and delivering a pool that stays watertight for the life of the building without a surface membrane, said Sam Annous, Director and Partner of Penetron Middle East. The team specified an integral approach combining three product groups:

Jeddah – October 02, 2026 -- The Mysk Al Wadi Jeddah Hotel, the first Mysk-branded luxury property in Saudi Arabia, will open in September 2026 after builders treated over 2,000 cubic meters of concrete with crystalline waterproofing admixture to counter high groundwater and chloride exposure at the Red Sea construction site.

General contractor specified PENETRON ADMIX for below-grade structures exposed to groundwater

Faraj Abdulkarim Est, the project's general contractor, required a waterproofing solution for below-grade concrete after excavation depths revealed elevated groundwater levels at the site in Jeddah's Obhur district, near the Jeddah Corniche. Sam Annous, Managing Director of Penetron Saudi Arabia, said the hotel's proximity to the Red Sea made resilience against chloride-rich conditions a parallel priority alongside groundwater control.

Trebinje – – September 22, 2026 -- The newly completed Trebinje Hospital in Bosnia and Herzegovina represents a $75.4 million (€65 million / ≈128 million BAM) investment by the Government of Republika Srpska, marking the largest healthcare infrastructure project in eastern Herzegovina's recent history.

Facility spans 17,500 m2 with 223 beds and six operating rooms

Located in the Pridvorci neighborhood of Trebinje, a city of roughly 32,000 residents, the hospital was completed at the end of 2025. The 17,500 m2 facility includes advanced diagnostic equipment such as MRI and CT scanners, along with fully equipped emergency and intensive care units.

Orlando – September 17, 2026 -- The newly completed Pod Zeleným Dvorom residential development in Budimír, near Košice, Slovakia, has integrated PENETRON ADMIX crystalline waterproofing directly into its concrete foundations, eliminating the need for a separate membrane waterproofing system.

Crystalline admixture replaces membrane systems at foundation stage

PENETRON ADMIX was added to the concrete mix during batching rather than applied as a surface treatment. Once mixed, its active ingredients react with water and concrete minerals to form an insoluble crystalline network through the pores, capillaries, and microcracks, reducing permeability and blocking groundwater intrusion.

Gąski – September 15, 2026 -- The Goose Bay residential development in Gąski, Poland, completed in September 2026, has integrated PENETRON ADMIX crystalline waterproofing technology into its below-grade concrete structures to counter chloride penetration from its Baltic Sea location just 40 meters from the shoreline.

Goose Bay comprises 58 apartments with six penthouses and a rooftop pool

The development offers units ranging from 28 to 70 square meters. Its proximity to the sea made water ingress and chloride penetration a critical design concern for the project team.

Dubai – September 08, 2026 -- Al Habtoor Tower, a 350-meter (1,155-foot) residential skyscraper on the Dubai Water Canal, was inaugurated in September 2026, ranking among the world's tallest residential buildings and relying on PENETRON ADMIX crystalline waterproofing to protect its below-grade concrete structures.

Tower delivers 1,740 apartments across 85 residential floors

The Al Habtoor City development spans a built-up area of over 25,000 square meters (274,000+ square feet), with three below-grade basement floors, a ground floor, and 85 residential floors. Units range from one-bedroom apartments (78-141 m2) to three-bedroom apartments (162-229 m2), with Ultra Residences and Sky Villas occupying the top six floors. The tower runs 24 high-speed elevators capable of 7 meters per second, described as the world's fastest.
