Peoria, IL, USA
We had a couple of areas with small wall cracks that eventually needed to be addressed. I had called around to a lot of places, but only Helitech were willing and able to do the epoxy injection instead of really expensive excavation. Their sales agent, Nick Kelton, was professional and great at explaining the process, and the technician came in to do the work and left no messes. Lifetime guarantee on their work. I highly recommend them!
