A key element in waterproofing a structure is the outer membrane. Besides sealing all of the joints, porous materials like concrete need to be sealed to prevent moisture incursion.

Urban Waterproofing often applies elastomeric coatings as part of a complete waterproofing program. Both highrise and stucco structures benefit from a finish that is cosmetic, but also durable and flexible enough to act as a moisture barrier.

Urban waterproofing applies Sonneborn, Sika, Dow Corning and GE Silicone systems.
