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.
A three-stage crystalline waterproofing system sealed leaks and cracks under tight construction deadlines
PENEPLUG, a rapid-setting cementitious repair grout, was applied first to seal active leaks. PENECRETE MORTAR, a crystalline grout, followed to fill and seal visible cracks. A final coat of PENETRON, a crystalline waterproofing material, was applied to outer concrete surfaces and tie holes to complete the treatment.
Crystalline technology creates a self-healing concrete matrix resistant to high hydrostatic pressure
According to Monterrubio Solis, the active ingredients in the Penetron System generate an insoluble crystalline network within the concrete, blocking water, chemicals and moisture even under the high hydrostatic pressure typical of large water cisterns. The treated concrete matrix also permanently self-heals microcracks, a property intended to limit further deterioration and extend the structure's service life.
Torre Valaria adds 125 residential units and amenities to a UNESCO World Heritage city
The tower offers 1-3 bedroom units ranging from 770 to 1,990 square feet (70-181 m2), along with a rooftop sundeck, jacuzzi, grill area, private cabanas, fitness gym, business center, game room, children's playroom, landscaped garden, dog park and underground parking. Guanajuato, a UNESCO World Heritage Site with a population under 200,000, is known for its colonial Baroque and neoclassical architecture built during the region's 18th-century silver mining boom.
