NWCW began under the vision and guidance of Marc Valdes. Marc has been in the concrete structure industry since 1980 when he began making repairs to various concrete products. In 1996, Northwest Concrete Waterproofing, Inc was formed and began making its impact on the industry. Marc wanted to create a company that could assist contractors and owners in their needs for stopping water intrusion and providing corrosion resistant coatings in both industrial applications as well in the waste water industry. As Marc began to grow his business, his reputation also grew. He has become known as the premier leak-stopping contractor in the state and his client list is exceptional. At the end of 2008, NWCW began an expansion program aimed at increasing it’s geographical market area. This expansion was driven by NWCW’s desire to follow its existing customers as they work in ever increasing distances from their home base, along with introducing quality service to new customers.
