We provide a full engineering assessment for concrete structures. 

Side Walk Repair

If you have a concrete sidewalk that is cracked or uneven, it not only looks bad, but it can lead to a fall or serious injury. The good news is the concrete does not have to be torn out and poured again to fix the problem. PDI can raise your sinking sidewalk and prevent it from sinking further. 

Concrete grinding or sidewalk cement grinding is one method we offer to remove sidewalk trip hazards typically up to 1 1/2″ in height where sidewalks have been lifted by tree roots, etc. Concrete grinding will remove the top finished layer of cement and leave an exposed aggregate finish where the concrete trip area has been removed, but will also bring your sidewalk trip and fall hazard back into compliance.

Out Door Commercial Parking Lot & Retaining Wall Restoration

Our experience of repairing warehouse and industrial concrete floor slabs has enabled us to develop standard repair details for the vast majority of floor slab defects.

Retaining walls serve to retain the lateral pressure of soil. More simply, retaining walls are used to hold back soil and substrate from moving due to the effects of gravity and erosion. Retaining walls are typically designed out of concrete, stone, wood (including railroad ties), vinyl, masonry, steel, or brick.

A Retaining wall may need to be repaired if 

  • Tilting Walls
  • Separation of Retaining Wall from Adjoining Walls
  • Forward Movement of Wall or Wall Sections
  • Buckling, Cracked, or Crumbling Walls
  • Rotted Wood
