Description of work: "Tear down and rebuild a 16-foot wall, water slide, waterfall and flagstone walk, and stabilize the foundation underneath it. Restore the landscaping and clean up."

Member comments: "We built a new home and put in a pool as the "magnet" for our 10 grandchildren. There is a 16-foot wall on a 30-degree hill holding a waterslide. However, the wall was starting to topple downhill.

"An engineer confirmed the wall was moving because foundation couldn't hold the weight and suggested helical piles to secure it. He recommended Cantsink. Today, the waterfall is working as planned and the slide is getting plenty of use from the grandchildren and the neighbor's little ones."
