Every spring, uneven areas appear in front of our garage. Either the ground is shifting, or the old flooring is tired. I'm thinking of completely removing everything and installing a new interlocking flooring. Could you tell me what to look for when choosing a contractor? Are there companies that not only install the flooring but also properly prepare the base so I don't have to redo it in a couple of years?

Spring unevenness is almost always a subgrade or drainage issue. If the soil is shifting, it means the underlying surface hasn't been properly prepared. When choosing a contractor, I'd look at how they describe the work stages, not just show pretty photos. It's important that they remove the old layer and compact the subgrade in layers. And it's best to get a written warranty.

We also decided to completely replace the old pavement. It was actually cheaper than resurfacing it every spring. We chose https://oakshs.ca/driveway-interlocking/ because they laid out the entire process step by step. First, they removed the old pavement, then created a solid base using high-quality materials. Their in-house team carried out the work without using third-party contractors. They explained and demonstrated every step, which gave us confidence. After completion, they conducted a final inspection to ensure the surface was level and stable. Since then, there have been no warping issues, so we are satisfied with their service.
