Protect Your Building from the Elements

Building a new residential or commercial building involves a multitude of steps. From laying the foundation to building the walls and eventually the roof, you follow a plan to create a strong structure that will last for many years.

But every building in North Dakota and the surrounding areas faces the elements of Mother Nature, especially moisture.

Whether it’s snow, rain or an oppressive dew point, moisture is always a threat to local buildings. To help ensure your structure stands the test of time for as long as it’s needed, it’s important to take the proper steps to protect it.

One vital step is exterior waterproofing. This is the most effective way to prevent water and moisture from passing through vulnerable areas into your building, such as the walls and floors. It ensures moisture protection for your building and helps prevent mold growth.

Our expert team at Cullen Insulation has vast experience identifying and applying the right exterior waterproofing product to meet your project’s needs, both residential and commercial, and protect your structure from the harsh elements. We provide the highest quality exterior waterproofing North Dakota area builders count on.

How and Where to Waterproof

Waterproofing is applied to exterior foundation walls on new commercial buildings as well as residential foundations or basements. It is regularly used on concrete block walls, poured walls, ICF forms, tunnels, and elevator pits.

There is a wide range of waterproofing materials available for the job, including fluid-applied waterproofing and self-adhered options. Rest assured, we only install products from the industry’s leading manufacturers and will work with you to determine the right waterproofing product for your project based on its specifications.

Benefits of Exterior Waterproofing

Dangers of Not Waterproofing Your Building

Every building is different. Commercial buildings require tailored exterior waterproofing solutions to account for complexities, size differences, and unique architectural features. But one thing that remains the same is the need for moisture protection for buildings. Taking measures now and waterproofing during new construction is the best way to help prevent serious issues down the road, like mold growth, structural deterioration, and costly repairs.
