Before & After

Ann Arbor, MI Driveway Repaired Using PolyLevel and TrenchDrain

A homeowner in Ann Arbor, MI needed help with their unlevel concrete. Slabs throughout the driveway, sidewalk, and garage had shifted throughout the decade since moving into this home. They suspected the trouble with sinking concrete was caused by a family of chipmunks and a mole. With no plans to move, the homeowner decided to fix the driveway, sidewalk, and garage. They called HomeSpec Waterproofing and Foundation Repair for help.


A senior project manager, Elon, went out to the home to evaluate the situation and provide a free inspection. He took measurements of the concerning areas and evaluated the integrity of the remaining areas as well. Afterward, he spoke with the homeowner to come up with a repair plan together. Elon explained that while critters may dig underneath the slabs, they are not the only cause of sinking concrete. The water from the downspout was causing soil to wash away. Elon suggested the repair consist of two parts, leveling the concrete and preventing it from sinking again. The leveling would be accomplished using PolyLevel® Injection Foam and NexusPro sealant would protect the joints. To further prevent soil from being washed away, Elon suggested extending the downspout and installing TrenchDrain™ Grated Draining Pipe. The homeowner agreed to this plan and was happy with the completed results! The team was led by Fred, a PolyLevel Foreman, and saw the project finalized.
