Duluth's Master Craftsmen in Building Envelope Restoration

About Us

Western Waterproofing Company was founded in St. Louis, MO in 1915 and since then has grown across the United States. Our Minneapolis operations opened in 1960 as Western Waterproofing Company – a local contractor specializing in waterproofing, concrete and facade restoration.

In 2015, Western celebrated our centennial and rebranded as Western Specialty Contractors to provide a more encompassing portrayal of our services.

Over the years Western has built a reputation for quality craftsmanship and professional service in the Greater Minneapolis area. In 2019, the Minneapolis office expanded and acquired a restoration contractor in Duluth, MN opening a satellite office. Along with Minnesota, we provide the same services to North Dakota, South Dakota, Wisconsin and Northern Iowa. 

Since opening in 1960, the office has grown, but its reputation as a quality restoration contractor has never wavered. We have been privileged to have worked on many of Minneapolis and St. Paul’s renowned buildings such as the Macy’s building, IDS building, City Center, Wells Fargo Tower, Foshay Tower, and Carlson Center to name a few.


Concrete Repair and Restoration

Concrete repair can come in many different forms from building facades to precast structures to parking garages. All of which are vulnerable when exposed to the weather. An effective maintenance routine on a parking structure can prevent costly repairs that can be disruptive to tenants and cause unexpected costs and safety concerns.

Masonry Restoration & Preservation

Masonry restoration is the phrase used for working with any form of masonry on an existing building that does not encompass building it from new construction. Restoration is tearing the masonry down and rebuilding to repointing and cleaning and sealing. Masonry structures are vulnerable to age, moisture, pollutants, building movement and deferred maintenance.

Epoxy & Urethane Grout Injection

Epoxy crack injection is an economical practice of repairing non-moving cracks in concrete walls, slabs, columns, and beams. Urethane crack injection also known as polyurethane or grout is a common way to seal and fill a leaking crack in concrete foundation walls and slabs. Either discipline provide an alternative method for repairing concrete without full removal and replacement or excavation.

Sealant & Expansion Joint Replacement

Got leaks? Exterior building sealant is the first line of defense for water intrusion on the building exterior. Neglect of this critical construction component can lead to interior and exterior deterioration of any building. Water intrusion is more than an inconvenience for property owners and tenants. Left unchecked, it can damage structural elements and shorten the useful life of buildings.

Structural Repair & Carbon Fiber Reinforcement

Structural repair can come in many different forms from full concrete column replacement, concrete beam reinforcement, externally bonded carbon fiber, supplemental steel installation, or repair and replacement to existing post-tension cables. All of which Western employs our own certified craftsmen and women who take pride in restoring America’s structures.

Deck Coatings & Wall Coatings

Considering applying a coating to your façade or parking structure? Coatings can be a fantastic cost saving and preventative maintenance measure, but they are only as effective as the caliber of preparation and installation. Whether it’s a planter, plaza deck, parking garage or façade, coating systems we install help preserve the useful life of your structure and reduce repair costs.

Terrazzo Restoration

Terrazzo flooring is widely used in hospitals, government buildings, and schools for its durability and beauty. It often requires waxing multiple times a year and shows wear over time. Our unique process can hone and polish existing terrazzo back to its original beauty and eliminates the need to ever wax again. In addition, we can repair unsightly crack and re-bond delaminated terrazzo.

Industrial Repairs

Industrial facilities such as mines, paper mills, refineries, manufacturing facilities, and foundries have massive investment in their facilities and are under constant stress. Western can complete structural concrete repair, injection, high performance flooring, secondary containment, grouting, hot floors, and chemically resistant coatings. Understanding your investment and the importance of time sensitive repairs, gives us the ability to select the correct products for each situation.


Concrete slabs drop from their original position over time because of foundation soil settlement, sinking or erosion. Lifting and realigning concrete slabs with grout is a fast and cost-effective to remedy your sinking concrete slabs. As concrete slabs sinks and or cracks, they pose trip hazards and provide an unstable surface for those crossing over it.
