Concrete Repairs
Before Construction Begins

Letters are sent each year in March to notify residents if their street is scheduled for concrete repairs during this year’s Pavement Management Program. Concrete repairs typically take place from March to July.

 

Within 1-2 weeks before construction, the City Project Inspector will visit the concrete installation site to mark the areas of replacement with temporary spray paint. In advance of construction, saw cutters may make superficial cuttings in the asphalt to separate the areas of asphalt and concrete to be excavated.

 

At least 24 hours before work begins, door hanger notices are left at houses where concrete repair is anticipated to occur. The door hanger will either indicate sidewalk or driveway work. No Parking signs are also placed on the road.

 

At this point, weather permitting, construction is ready to begin.

 

Construction Process

 

The asphalt removed extends about 18 inches out from the street gutter. The asphalt is excavated along with the existing curb, gutter and immediate sidewalk area to make room for the new ramp or sidewalk.

 

Although parking will not be allowed in the immediate area during construction (as noted by No Parking signs), cars are often still able to drive down the street with guidance from construction flaggers.

 

Once excavation is completed and materials have been hauled away, wooden or steel “forms” are installed to help shape the concrete as it is being placed. The soil is graded to the appropriate slope for the ramp/sidewalk and for proper drainage of stormwater. The concrete can then be placed.

 

  • It may take 2-4 days to complete the process of saw cutting, excavating and hauling, creating the forms, grading the soil and placing the concrete for the curb, gutter, affected sidewalk and ramp. Construction tape and barriers are put up while the concrete cures.
  • Curing can take 1 to 3 days, depending on weather. During colder temperatures, construction blankets may be placed over the concrete to speed up the curing process.

 

After Completion

 

Once the concrete cures, the forms are removed. The excavated area is backfilled and asphalt is patched along the new curb. Asphalt patch backs typically occur 24 to 72 hours after concrete replacement. At this point, the ramp or sidewalk is completed to the point where it is safe for residents to use the area, drive their cars freely and park on the street.
