Concrete Repair in River Falls, Wisconsin.

River Falls takes a right-of-way permit from everyone doing work in a sidewalk, boulevard, alley or street, and it issues the permit to the property owner or agent with the contractor named on it too. A deposit goes up before the permit issues and the city holds it for a year after the work is finished. The city publishes its own standard detail plates for curb and gutter sections, for concrete drive approaches in three types, and for a typical sidewalk, so the section that goes back in is drawn before anybody prices it. The commercial ground here is the four corporate parks on the north and west sides, the Allina hospital on East Division Street, the university campus, and the downtown blocks along the Kinnickinnic.

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.
