OUR SERVICES / EXISTING BUILDINGS
Proper waterproofing is essential to preserve the lifespan of a building and its components. Effective waterproofing does not merely involve the prevention of water from entering buildings. It also requires a thorough knowledge of materials and engineering to ensure water can exit a building where infiltration is unavoidable.
Water penetration into a building’s facade can lead to corrosion of embedded ferrous metals, degradation of façade materials, and leakage into occupied portions of the building. Corrective measures to prevent water penetration are usually not implemented until leakage or an unsafe condition is reported. Many municipal façade ordinances recognize that water infiltration through a building’s facade should be immediately addressed.
HLZAE follows a methodical approach to waterproofing that considers a building in its entirety and the most vulnerable locations. Our expertise includes testing both to identify the causes of existing leaks and to confirm the performance of new installations. The various details and materials we use address obvious water conditions such as falling and windborne rain, in addition to complexities such as New York City’s freeze-thaw cycles and potential damage caused by water trapped within façades. HLZAE provides waterproofing services for new construction or rehabilitation of commercial, institutional, and residential properties.
