How to Repair Sidewalks

Concrete removal and replacement is the traditional method for sidewalk repair when the damage is so extensive that alternative methods are not enough to make the necessary repairs.  Today there are a wide variety of sidewalk repair technologies available that, when implemented correctly, can result in major savings of both time and money.

In some instances if the sidewalk concrete is in good condition and there is only a vertical misalignment along the seam between slabs (See Stub Toe and Longitudinal Slope in Sidewalk Inspection Criteria) it may be possible to correct the problem by one of the following methods.

A sidewalk permit is only required for the replacement of sidewalks. The permit can be obtained through the Building and Zoning Department.  You may only hire a contractor registered, licensed and bonded with the City of Oregon to replace your sidewalks.  A list of licensed sidewalk contractors can be obtained through the Building and Zoning Inspection Department

Contact the Department of Public Service at (419) 698-7047 to determine if your sidewalk could be repaired by any of these methods or for additional information related to these items.

1. Concrete Raising (Slabjacking)

  • Concrete raising is a repair method that lifts concrete sidewalk slabs back to their original position by pressure injecting cement or non cement material under the sidewalk.  Holes are drilled through the slab and grout is injected to raise the concrete slab or to fill the voids under them. Although it is less costly than replacement, it is only effective on sunken sidewalks.  There are many contractors that specialize in performing this type of work.

  • This is a good alternative when the sidewalk concrete is in satisfactory condition with no cracks or structural defects.  One draw back to this method is the greater the slab needs to be adjusted the greater the possibility of the slab settling in the future.

2. Concrete Grinding: 

  • before_afterConcrete grinding is a relatively new technology used to remove trip hazards in concrete walkways by reducing slight protrusions on a concrete surface by removing a thin layer of concrete.  After grinding, the surface is left even on both sides with a gradual slope instead of a dangerous edge.

  • Concrete grinding is a good alternative if the lip (stub toe) between concrete slabs is between 1/2" to 1".

3. Repairing Cracks, Gaps or Pits in your Sidewalksfig1

  • Cracks in sidewalks must be enlarged before they can be satisfactorily repaired. Enlarge the crack along its entire length with a cold chisel and hammer. 

  • Make the crack wider at the bottom than at the top. This is known as undercutting. It helps to bond the new concrete with the older concrete.

  • Undercut the crack to a minimum depth of 1". The depth of the undercutting depends on the size and depth of the crack to be repaired.

Sidewalk Inspection Criteria

The following is the criteria the City of Oregon uses to determine if a sidewalk is deficient and is need of repair or replacement.

If a section of sidewalk meets any of the following criteria it will be marked with a white letter denoting the sidewalk deficiency.  Sidewalk slabs marked with a white letter will be the responsibility of the property owner to repair or replace. 

Sections of sidewalk marked with a white “O” will be replaced or repaired at the City of Oregon’s expense if it is determined that a public infrastructure (sewer and water mains, sewer manholes, catch basins, ... etc.) or a tree in the right of way has caused the damage.

Sidewalk Program

The City is currently inspecting sidewalks in the 2010 Sidewalk Program Area to determine which sidewalks are in need of repair. Following the inspection of the entire program area, certified letters will be sent to the properties with the noted sidewalk deficiencies.

The City of Oregon has implemented a Sidewalk Program to improve existing sidewalks that are in need of repair or replacement. Per Section 909.02 of the Oregon Codified Ordinances, "Every owner of any lot or parcel of land shall keep and maintain sidewalks now or hereafter constructed along all streets adjoining such land in good order and repair and free from nuisance."
