Concrete Repair in Spooner, Wisconsin.

Spooner's code puts the cost of sidewalk construction, repair and reconstruction on the property owner (62-47), while curb and gutter is laid, repaired or replaced by the city itself, either on a petition from the abutting owners or by council resolution. When the council orders a walk replaced, the owner has 20 days from service of the notice under Wis. Stat. 66.0907(3)(c) before the city does it and the cost goes on the tax roll. The city's spec calls for six sacks of cement to the cubic yard testing 4,000 pounds at 28 days, and seven inches of thickness where a commercial walk crosses a driveway approach. Reconstructing or enlarging a drive inside the street right of way needs a permit with a drawing and the materials named, and a commercial property is allowed two access driveways at up to 35 feet. River Street downtown is Highway 63 and Maple Street is Highway 70, so an approach onto either goes through the state under Wis. Stat. 86.07(2)(a) and Trans 231 on top of the city's permit.

Four things take concrete apart here, and each one goes after a different part of a property. A sidewalk panel sits on saturated ground or over a root. The water under it freezes, expands and lifts the panel. In spring the ground thaws and settles, and the panel does not go all the way back down with it, so what was flush in October is a lip in April. Then a plow blade catches that lip every storm for five months and breaks the leading edge off it. A curb takes the plow head on. The blade rides up the gutter, catches the curb face and takes the nose off in chunks. Salted slush sits in the gutter longer than anywhere else on the lot, because the gutter is where everything on the lot drains to, so the gutter is where the surface scales first. De-icer does the same thing to flat concrete. Chloride pulls water into the surface and runs more freeze and thaw cycles through it in a season than the weather would on its own. The mortar skin comes off in flakes and the aggregate stands proud. The approach at the street is a joint between two slabs that belong to different people. The street sits on a road section and a deep base; the drive sits on whatever was there. Frost gets under the shallower one first, the apron cracks along the gutter line, and that crack takes water into the base under both of them.
