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.

Orlando – October 09, 2026 -- Civil engineers on Slovakia's 14.9-km D1 Hubová–Ivachnová motorway section specified the Penetron System of crystalline concrete waterproofing for exposed bridge curbs, targeting damage from water, freeze-thaw cycles and de-icing salts, according to Penetron Group.

D1 section adds a northern bypass of Ružomberok across mountainous terrain

The section forms part of Slovakia's principal east–west motorway corridor. It creates a northern bypass of Ružomberok, a center of the country's paper industry and a tourist destination, diverting transit traffic from the urban area.

The project comprises 19 bridge structures, three interchanges and the roughly 3.6-km twin-tube Čebrať Tunnel. The route crosses complex geology and faces severe seasonal exposure, which raises the requirements for concrete durability, waterproofing and corrosion protection.

Guanajuato – – September 19, 2026 -- The Penetron Group repaired and waterproofed a severely deteriorated below-grade concrete water cistern at Torre Valaria, a 20-floor, 230-foot (70-meter) residential tower that became Guanajuato's tallest building and welcomed its first residents in October 2025.

General contractor ICREAR flagged structural damage and active leaks in the drinking-water cistern

PENETRON México was contacted by ICREAR after inspectors found significant leaks, structural damage and water loss in the cistern designated to store drinking water for the tower's 125 apartment units. Rodrigo Monterrubio Solis, Country Manager of PENETRON México, said the team had to move quickly because construction was nearing completion.

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.
