I had water leaking into my basement from the wastewater exit pipe. Basement Systems USA tried a repair job from the inside. The next rainfall I had more water leaking in the same spot. The company came back out and dug down from the outside and resealed that way. We've had a few big storms since and not a drop in the basement. Unlike the first company I hired for this repair, Basement Systems stood by their guarantee and did what it took to get it right. Awesome job. Highly recommend!
