At the State Bank of Plzen, we carried out critical waterproofing to safeguard the building’s foundations and underground facilities. The main challenge was addressing complex structural joints and preventing water leaks in an aging structure with tight access constraints. To overcome this, we designed a tailored waterproofing system using flexible membranes and sealants, combined with careful surface preparation to ensure full adhesion. Our detailed approach guaranteed a durable, watertight barrier that protects the bank’s infrastructure and operations for years to come.
