Crystalline Waterproofing Technology Deployed in Greek Power Plant Cooling Tower Repairs

## Crystalline Waterproofing Technology Deployed in Greek Power Plant Cooling Tower Repairs Repairs to the cooling tower pedestals at the Komotini Thermal Power Plant in Rhodope, Greece, were completed in late 2025, with the Penetron System of crystalline concrete waterproofing and repair solutions specified to ensure long-term structural durability, according to a PR Newswire release from Penetron. The Komotini facility, a thermal power plant operating in the demanding climatic conditions of the Rhodope region in northeastern Greece, required targeted intervention to address deterioration of its cooling tower pedestal structures — components that are subject to constant moisture exposure, thermal cycling, and mechanical stress inherent to power generation environments. Penetron's crystalline technology works by generating insoluble crystals within the concrete matrix when exposed to water, effectively sealing cracks and capillary pores and providing ongoing, self-sealing waterproofing protection over the structure's service life. This approach is increasingly favoured in industrial and marine-adjacent infrastructure projects where conventional surface-applied membranes may be vulnerable to mechanical damage or delamination. While the Komotini plant is a land-based energy facility, the application is of direct relevance to the maritime and coastal energy sector. Cooling water infrastructure at coastal and port-adjacent power stations — including those supplying shore power to ports and bunkering facilities — faces similar or more aggressive deterioration challenges due to saline air exposure and tidal influences. The specification of crystalline concrete systems in such environments reflects broader industry recognition of the technology's suitability for structures in contact with water under pressure. The Penetron Group, which markets its products globally across marine, industrial, and civil construction sectors, positions its crystalline system as a lifecycle cost solution, reducing the frequency and cost of repeat repair interventions at critical infrastructure assets. The successful completion of the Komotini repairs adds to a growing portfolio of energy sector references for crystalline concrete waterproofing technology, and may inform specification decisions at similar facilities across the Eastern Mediterranean region, where aging thermal power infrastructure continues to require modernisation and structural remediation.
