The new Caption by Hyatt Hotel in Nashville, Tennessee, opened its doors to guests in January 2025. The hotel includes a multi-level below-grade parking garage treated with PENETRON ADMIX SB, a crystalline waterproofing admixture, to provide permanent waterproofing protection for the concrete structures.
A neighborhood on the southern edge of downtown Nashville, the capital and largest city (ca. 690,000 inhabitants) of Tennessee, the Gulch is a trendy and hip district of the city. This once-abandoned industrial area has undergone a comprehensive revitalization and is now a popular destination for locals, students, and tourists.
The new Caption by Hyatt Hotel in the Gulch comprises 210 guest rooms housed on 12 floors and a 150-car underground parking garage (on three basement floors). Amenities include indoor and outdoor meeting spaces (2,200 square ft2 / 200 m2), a fitness center, common spaces for working, socializing, or hosting small events, a coffee shop, eatery, artisanal market, cocktail bar, as well as The Talk Shop food & beverage (F&B) concept, which is an all-day hangout and coffee shop.
“Exposed to the outdoor elements and high groundwater levels, the concrete retaining walls of the hotel’s below-grade parking garage required a durable solution to resist moisture,” notes Richard Farmer, Eastern Sales Manager for Penetron USA. “Our local Penetron team provided key product information and technical support to ensure an effective concrete mix design.”
The active ingredients in PENETRON ADMIX SB generate a non-soluble crystalline formation throughout the cracks, pores and capillary tracts of the treated concrete. These crystals permanently self-heal and seal micro-cracks, pores, and capillaries against the penetration of water or liquids from any direction. The concrete is now impermeable with increased durability and service life.
imi, the concrete supplier for the Caption by Hyatt Hotel, added PENETRON ADMIX SB – in soluble bags – to the concrete mix used for the below-grade retaining walls and foundation slab. Added during the batching phase, the convenient pre-measured soluble admixture bags dissolve quickly and completely. Using pre-measured soluble bags ensures easy dosage, batching and helps save time and costs – and reduces the permeability of the finished concrete.
“Permeability is crucial for concrete durability,” explains Richard Farmer. “PENETRON ADMIX reduces shrinkage cracking and its ability to self-heal hairline cracks over the service life of the structure minimizes the need for any maintenance over the lifespan of the structure.”
