Concrete Repair in Sparta, Wisconsin.

Sparta's snow contract takes in houses, city buildings and places of worship and leaves out the apartments over the downtown businesses, so a downtown owner clears his own frontage. The ordinance wants the full width of the walk clear within 24 hours of a storm ending, five feet of the plow bank off at a corner lot, and nothing from a sidewalk, driveway or parking lot pushed back onto a city street or a neighbor's walk. Under Wis. Stat. 66.0907 the council can order a walk that's unsafe or defective replaced, give the owner 20 days, and put the cost on the tax roll as a special charge spread over as many as ten years. An entrance on Highway 16, 21, 27 or 71 is an alteration in a highway, and Wis. Stat. 86.07(2)(a) says nobody makes one without a permit from the authority that maintains the road. South Pointe Business Park sits at the I-90 and Highway 27 junction, and its second phase went in with curb and gutter and resurfaced streets.

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.
