Keeping a Princess Dry and Durable with PENETRON


Opening just in time for the late winter and spring season in Greece, the luxurious Blue Lagoon Princess Hotel chose PENETRON crystalline technology to keep the complex dry and resistant to incursion of saltwater.
A village style 238-unit luxury complex, the Blue Lagoon Princess Hotel is located on Kalives Beach in the Halkidiki region / Gulf of Toroni in Northern Greece. The hotel features several swimming pools, a spa with an indoor pool, and three restaurants and bars.

The water’s fine: All below-ground and exposed concrete was built as a “white tank” structure that creates an integrated, durable solution for concrete exposed to saltwater.

“The hotel complex is only a few meters from the Aegean Sea; this meant the construction needed to be able to withstand the many challenges facing such a large project,” says Theodor Mentzikofakis, General Director of PENETRON Hellas.

The reinforced concrete needed an absolutely waterproof solution for protection from corrosion due to chloride penetration and also resistance to concrete carbonation. Project engineers and the Douros Construction Company consulted with the specialists at PENETRON Hellas. PENETRON ADMIX was specified to treat all below-ground and exposed concrete structures in a “white tank” solution, which creates an integrated, durable concrete structure that is permanently waterproof.

This innovative solution takes advantage of the PENETRON crystalline waterproofing technology, which reduces permeability by permanently sealing micro-cracks, pores and capillaries. This effectively protects the concrete against water penetration and corrosion from chloride penetration and carbonation, even under the hydrostatic pressure conditions found on the shores of the Aegean Sea.

In addition to mixing PENETRON ADMIX into the concrete during batching, PENEBAR SW waterstop strips were applied to permanently seal all resulting construction joints; both PENETRON topical crystalline material and PENECRETE MORTAR were used to complete the repair of cracks that may have appeared after the initial phase of construction.

“The Blue Lagoon Princess Hotel project illustrates how PENETRON offers high performance products, as well as a support team that works with engineering and construction teams to help ensure a durable and waterproof concrete structure.,” adds Robert Revera, President and CEO of The PENETRON Group.
