-sloped floors -cracks in foundations -gaps in slab floors -cosmetic distress within the house
Call Avalon for an evaluation. We will perform an accurate floor level survey using the most modern technology, and study the foundation for deficiencies.
Avalon will then recommend the remediation and, as applicable, proven engineers. If engineering is indicated, Avalon will work with the recommended engineer, or your existing project engineer, to produce accurate and cost-effective plans.
Often, houses suffering differential settlement can easily be repaired using helix piers as underpinnings.
This slab-on-grade home was 8.4 inches out-of-level. This remediation required the installation of 9 vertical helix piers and 4 diagonal helix tiebacks. We then lifted the house using lifting brackets attached to the vertical piers, to bring the floor level.
Because the perimeter foundation of this particular house was too weak to span from pier to pier, we built a grade-beam from pier to pier, doweled into the existing perimeter.
Pushing down on the helix pier, we can lift the concrete foundation back into a level position.
After lifting, the nuts are tightened, jack removed, and concrete poured.
With our portable helix installation rig, we can get anywhere a pier is needed.
In this case, the helix pier is installed through the floor of a dining room.
We have put a 38,000 pound capacity pier through the floor of a linen closet!
If the structure needs a deep foundation, helix is the no-brainer in retrofitting. In this example, the engineer recommended complete foundation replacement due to crumbling and sinking of the foundation.
Typical retrofit helix pier ready for concrete.
In this example, the foundation, was strong enough to remain in place, and span from pier to pier.
After the concrete was poured, Avalon repaired the crack using pressure epoxy injection techniques. Avalon is certified in pressure epoxy injection.
In this example, helix piers were required behind a house where only 18" of clearance existed between the house and the soldier piles of a retaining wall.
Avalon installed 182 helical piers, supporting 5 buildings of a sinking apartment complex.

This sunroom had dropped a full 6 inches at the right front corner. Avalon installed helix piers and lifted the slab level. Grout was then pumped under the slab.
