In the Upper Midwest, buildings must withstand extreme temperature changes, heavy rain, snow, and freeze-thaw cycles. At Waterproofing by Experts, we use proven waterproofing and air barrier systems designed to protect foundations and structures in the demanding climates of Minnesota, Wisconsin, Iowa, and the Dakotas.

Foundation Waterproofing

Foundation waterproofing is essential for preventing water intrusion into basements and below-grade structures. This typically includes the application of liquid or sheet waterproofing membranes to exterior foundation walls, along with proper drainage systems. These systems create a protective barrier that keeps groundwater and moisture from entering the structure.

Below-Grade Waterproofing Membranes

Below-grade membranes are commonly used on concrete foundations, retaining walls, and elevator pits. These membranes are designed to resist hydrostatic pressure and prevent water from penetrating structural concrete. Both fluid-applied and sheet-applied membranes are commonly used depending on the project requirements.

Air Barrier Systems

Air barrier systems help control the movement of air and moisture through a building’s envelope. In cold climates like Minnesota, air barriers are critical for improving energy efficiency, preventing condensation inside walls, and protecting insulation systems. Properly installed air barriers also help reduce heating costs and improve indoor comfort.

Fluid-Applied Air Barriers

Fluid-applied air barriers are sprayed or rolled onto exterior walls to create a seamless protective layer. These systems are widely used on commercial buildings and multi-family construction because they can easily seal around penetrations, joints, and irregular surfaces.

Sheet-Applied Air Barriers

Sheet air barrier systems consist of durable membrane sheets applied to the building exterior. These membranes provide a consistent and reliable barrier against air and moisture intrusion and are commonly used in commercial and institutional construction.

Drainage and Protection Systems

In addition to waterproofing membranes, drainage boards and protection layers are often installed to direct water away from foundation walls and protect the waterproofing system during backfilling.

With nearly five decades of experience, Waterproofing by Experts understands the unique challenges that Midwest weather places on buildings. Our team installs high-quality waterproofing and air barrier systems designed to provide long-term protection and performance.
