Some of the costly features of urban developments include concrete sidewalks, curb and gutter, driveway aprons and warehouse floor slabs. Settlements within these structures can cause uneven surfaces, water ponding and trip hazards associated with faulting. GeoGrout can correct the problem by performing what is commonly known as slab jacking or mud jacking.
Initially, the 40 mm (1 ½ inch) diameter core holes are sealed with a foam plug. Within 2 – 7 days, each core hole will be filled with a high strength grout and finished to match the adjacent surface. The grout patch initially will appear darker in color, however, over time these areas will fade to the color of the driveway. On exposed aggregate driveways; each core is returned to its original location. These cores are set in place with a high strength grout, which is tinted to closely match the color of the existing driveway.
No, the process should not damage the sod. There are instances where the sod adjacent to the sidewalk edge may be disturbed; however, this generally happens when the soils are saturated. Therefore we suggest refraining from watering the sod a minimum of 1 day prior to mudjacking.
Yes, however, due to the minimal surface area available to effect lift, we combine mechanical and mudjacking techniques to raise the structures to required grade.
The sidewalk or driveway area should be clear of vehicles when it is lifted. The mudjacking process will take approximately 20 – 40 minutes and in most cases, the sidewalk or driveway can be returned to service shortly after completion.
