Silty Ground Cracks Prince George Slabs
A lot of Prince George sits on fine silt and clay laid down by an ancient glacial lake. The City's own engineering reports describe that soil as prone to frost heave, because it holds water and forms ice layers when it freezes. Garage aprons, unheated shops and older slabs crack and step at the joints because of it.
Concrete floor repair begins by working out whether a crack is still moving. A moving crack gets a flexible filler. A stable crack is chased out and packed with epoxy so it will not telegraph through the new floor.
Concrete Grinding Before Every Coating
Diamond grinding is step one on every floor we install. It strips old paint, glue, oil and the soft surface of the concrete, and it leaves a rough texture the coating can grip. It also takes down raised lips at cracks and joints.
Concrete floor repair and grinding go hand in hand. We grind, patch, then grind the patches flush so nothing shows through the finished surface.
Concrete Floor Repair For Failed Coatings
A peeling coating usually failed for one of three reasons. The slab was never ground, moisture pushed up from below, or the coating was far too thin. We find the cause before we start, then grind the old coating off entirely.
If an old coating is sound and only worn, we can sand the wear layer and recoat it, which costs far less than a whole new floor. After the concrete floor repair, most homeowners go on to a new garage floor coating.
Concrete Floor Repair For Bare Floors
Not every repaired floor gets a coating. Some shops just need broken joints rebuilt and potholes filled so carts and forklifts roll smoothly again. We can do that work on its own and seal the slab afterwards if you like.
Concrete Floor Repair For Salt-Scaled Garages
Salt scaling looks like the top of the slab has peeled away in thin patches, usually near the overhead door. It shows up in a lot of Prince George garages that spent years without a coating.
We grind off the loose surface, fill the low patches with a polymer repair mortar and grind them flat. That concrete floor repair gives the slab a sound face again, and a coating on top keeps the scaling from coming back. Deep damage can be built back up to the old level, so the floor still drains toward the door.
