Photo Album: Foundation Settlement Repaired in Tucson, AZ 9.2021

Homeowner’s Concerns/Goals: The homeowner’s main concern is the addition, specifically the slab crack and also the addition being constructed without a footing. After examining the home and performing the manometer survey, we believe the home could be experiencing foundation settlement at the southern portion of the home (addition) as shown by the Signs of Stress and lower readings on the Topographical 2D Map. The drop off in floor elevations on the topographical map is consistent with a foundation settlement pattern. Foundation Settlement can be caused by one or any combination of many factors including sub-grade saturation of moisture due to poor drainage, years of storm runoff, plumbing leaks, improper compaction, the lack of a proper foundation system, and/or (in most cases) natural earth movement. We believe that the proper way to permanently stop the perimeter foundation settlement is to underpin the areas that are experiencing movement.

Stair Step Cracks in Brick or Blockwork

Cracking in brick or blockwork is a common sign of a foundation problem.

Exterior Wall Separation

As the foundation begins to settle, wall separations may appear. The longer the foundation repair is delayed, the more costly the repair can be.

Hydraulic Lift

Piers can be driven a variety of ways. Here, the foundation support piers are driven hydraulically.

Tools of the Foundation Repair Trade

Foundation Push Piers, excavation & plywood to cover open dig sites that we are not currently working on.

The result of the floor level read indicates foundation settlement.

Horizontal Cracking

Upon lifting, horizontal cracks like those seen here, may appear. This indicated both dry soil & a successful attempt to lift!

Mid Foundation Repair Project

Before we begin, plastic is laid down to protect existing landscaping. Excavated soils are placed on the plastic to make backfilling an easier process.

Foundation Underpinning

The essence of the technology is using hydraulic rams to deliver up to 70,000 lbs. of force to drive a high strength steel shaft down to competent bearing strata, which is around 20 ft. deep in the Arizona area.
