- About MTI
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:
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. Contact Us
"We have been working with Masonry Technology Inc. for years. They have outstanding customer service and are always willing to go the extra mile to help you. If you need a specification image for a builder or homeowner on the "right way" for an install they have everything you need. Their on-site training for our crew was very beneficial. Adam made everything very easy to understand. We love working with them and their products. We strongly recommend using MTI on every project we do."
