"When the gazebo in the courtyard area of the Minneapolis-St. Paul Airport Courtyard by Marriott came into some disrepair, we contract Koppen Concrete & Masonry for their professional assistance.  We are greatly appreciative of the nice job they have done and will not hesitate to contact them for any future projects that we may have."

"I would like to thank David Koppen and his crew for the masterful job they did in replacing our old sidewalk and building a solution to our gutter drainage run-off issue.  David came up with a drainage system that allowed the water pass through a trough through the sidewalk.  Some of this had to be handmade and they did an exceptional job.  I would recommend Koppen Concrete & Masonry to any business or individual that wants a problem free project completed with no hassle."

"I truly appreciated your willingness to discuss what my options were with respect to various techniques, cost saving options and explaining to me what had been wrong with the prior concrete installation.  I only wish that the entire driveway would have been done by you initially.  My investment with your company was money well spent."

"I needed to rebuild a crumbling interior foundation corner in my farmhouse basement. It looked hopeless to me since the corner had all been eroded away. Dave Koppen and his staff came and rebuilt the corner foundation better than the rest of the foundation. Dave and his crew did a fantastic and thoroughly professional job. I won't hesitate to call Koppen Masonry and Concrete for any stone or masonry work I have in the future."
