Above & Below Grade Waterproofing
A continuous waterproofing envelope, ensuring water stays out and your building stays dry.
What Is Above & Below Grade Waterproofing?
Above Grade Waterproofing protects exposed building exteriors; walls, facades, balconies, and roofs from rain, wind-driven water, and surface runoff.
Below Grade Waterproofing protects foundations, underground garages, basements, and other structures in constant contact with soil and groundwater.
Why It Matters for Commercial Properties
Moisture intrusion in commercial structures often leads to:
Structural deterioration from long-term water exposure
Tenant complaints due to leaks or mold growth
Increased operating costs from damaged systems or finishes
Liability risks tied to unsafe conditions
Above & below grade waterproofing ensures long-term performance, compliance with building codes, and protection of your investment.
