17 years ago Helitech originally installed helical screw anchors on my wall that has a 30-foot horizontal crack. My wall recently moved very slightly so I called Helitech to come back out to inspect the wall. They lived up to their warranty by adjusting the anchors and adding carbon fiber material to my wall at no extra cost. I also decided to pay for epoxy injection for the crack in order to stop the leaks that occurred when it rained. The work was performed in December right before the recent storms that caused record flooding in St. Louis. I was amazed that my basement was completely dry for the first time since I have owned the home even with the massive amounts of rain. I was impressed with their warranty service and would definitely recommend epoxy injection for leaks.
