Concrete Repair in Cornell, Wisconsin.

Cornell took the option the sidewalk statute gives a city and wrote the cost split into its own code. The city pays the entire cost when curb and gutter is reconstructed or repaired, and a property owner pays a quarter of the cost when a sidewalk is reconstructed or repaired. New curb, gutter and sidewalk is a fifty-fifty split instead, and an owner who wants any of it petitions the Common Council between July and September to be considered for the following construction year. The specification is the state's rather than a local one: public sidewalk here is built to the WisDOT standard specifications and poured in Grade AA air entrained concrete. A driveway permit comes from the Common Council, an entrance is capped at 26 feet at the street edge of the walk without special permission, and any sidewalk that vehicle travel has damaged or left inadequate has to be replaced along with the approach.

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.
