Conditions where outdoor concrete has already begun to sink is not uncommon in British Columbia and is often the result of shifting, a weak soil base or erosion. It causes driveways, sidewalks, walkways, concrete steps or patio areas to become tripping hazards and can affect property value.
British Columbia soil has a variety of soil types, ranging in density and load-bearing capacities. When the weight above the soil exceeds the soil below, the soil will compact and settle. Clay and silt can also cause soil to compact when it becomes dry. Regardless of the reason, once soil becomes compact, heavy concrete above the soil will sink and crack. It's a gravity thing!
While it is a very noticeable problem, with the right contractor, it can have a very simple solution.
Previously, sinking concrete was repaired by a technique called "mud jacking" that uses a thick slurry to fill in the gap underneath the sunken concrete. While effective, it is not the most efficient way to solve the problem, and adds more weight above the compacting soil.
Today, select contractors in British Columbia are trained and certified to provide a better alternative to mud jacking. PolyLevel is a less intrusive, lighter weight solution that doesn't add more weight to the problem.

Comment: A portion of my backyard's 5" thick concrete patio slabs measuring 21.5' x 10' settled and caused reverse sloping. To compare the cost of replacing these slabs, please provide a quotation for leveling these slabs back to the original slope.

Comment: Water is pooling on our concrete walkway (which appears to be sloped towards the house) where it meets the asphalt driveway. Can I get someone to come by ASAP to advise, as I'm getting my driveway sealed next week. Thanks!

Comment: Basement slab requires lifting. Originally placed in 1972 and was slab jacked in the late 1990's and has now settled again. Some areas have 12 x 12 tile and wondering if holes can be drilled between grout lines to limit damage to the tiles ?
