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 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.
Our expert team at Cullen Insulation has vast experience identifying and applying the right waterproofing product to meet your project’s needs, both residential and commercial, and protect your structure from the harsh elements.
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 are a wide range of waterproofing materials available for the job, including fluid-applied 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 based on the specifications of your project.
