Partner with the Experts

Hi, I’m John Koester-owner of MTI.  I have been in the construction industry for more than 40 years. I was a card-carrying mason and cement finisher, and for many years operated my own masonry construction business in the Minneapolis-St. Paul area.  I have an extensive background in waterproofing systems in the areas of forensics, design and installation oversight.  I have written many articles on the topic of building moisture management at all levels of the building enclosure and have worked with architects and builders throughout North America to design the right moisture management system for their projects or to remediate problems that were the result of improper attention to moisture management when the structure was originally designed and built.

I founded MTI over 25 years ago with the idea of improving the existing technology for weep systems. To this day, all of MTI's technology, from inception to design and manufacturing is laser-focused on solving building moisture problems.  Beyond our great products, we strive to make sure that your experience partnering with MTI is fundamentally better than with any other building moisture management product manufacturer.  This includes:

  • Your calls are answered by a live person
  • You have access to MTI’s unrivalled subject matter expertise
  • You will receive help in determining the right products for your project
  • You will receive help with creating custom details for your project, if needed
  • Responsiveness--MTI is so nimble that it can often ship products same day, create details in a day, etc.
  • Custom products - we may even be able to create custom products for you when needed (limited circumstances)

I would like to invite you to partner with MTI on your next project.  We would be happy to design a moisture management system that’s exactly right for your unique building.  If you are interested in learning more or have a specific project you’d like to discuss, contact us today.
