What foundation type works best for your home?

Concrete Piers

Concrete Piers | Foundation Types

  • Hand-dug perimeter excavation, 1-4 feet deep, in the original non-supportive soil.
  • Large excavation area.
  • NOT driven to bedrock; supported by same expansive soil that created the original problem.
  • Continued expansion &/or shrinkage of soil may lead to call-backs and additional foundation problems.

Concrete Piers with Mud Pumping

Mud Pumping | Mud Jacking | Foundation Repair

 

 

 

  • Mud is forced under newly formed concrete piers (concrete should harden for 28 days)
  • NOT designed to contact bedrock; supported by same expansive soil that created the original problem.
  • Continued expansion &/or shrinkage of soil may lead to call-backs and additional foundation problems.

Hand Dug Drilled Concrete Piers

Concrete Piers

  • Much more labor intensive.
  • NOT driven to bedrock; supported by same expansive soil that created the original problem.
  • Continued expansion &/or shrinkage of soil may lead to call-backs and additional foundation problems.
  • Aesthetic repairs delayed while concrete hardens and grout is inserted between pier and footing.

Pre-Cast Short Concrete Cylinders (not illustrated)

  • This system has many limitations and flaws due to its design. Relatively short pieces make alignment during driving very difficult.
  • Resistance against the soil it is being driven through is very high due to its diameter therefore limiting its ability in most cases to be driven to bedrock; supported by same expansive soil that created the original problem.

Helical Anchors

Helical Anchors | Different Foundation Types

 

 

 

 

 

  • Designed for holding things down, not up.
  • Works well for tie backs on bowing walls and can be adequate for supporting some light structures (porches, etc.).
  • The helical blade becomes the base of the pier.
  • NOT driven to bedrock; supported by same expansive soil that created the original problem.
  • May require adjustments which can be troublesome and costly.

In Conclusion…

Perma Jack Steel Pier System
Concrete Piers are sometimes cheaper initially than steel driven piers, but the inability to drive to the depths needed to reach bedrock or load bearing strata creates the necessity for frequent post installation adjustments. Rooted in the expanding and contracting soil that initially caused the problem, problems are likely to continue.

Most concrete pier systems inadequately secure and align the pier sections. The strength of the pile is in the strength and alignment of the pier sections. Concrete piers cannot offer the same strength and reliability of alignment as the Perma Jack System.

In areas of constantly wet soil, whether from poor soil conditions or poor drainage due to improper grade around the home, concrete piers will continue to settle in the soft soil or clay. Many of these companies offer soil injections to help alleviate the problem, usually requiring service contracts for repeated treatments which significantly adds to the inconvenience and overall cost of the repair.

Perma Jack foundation repairs are unaffected by such conditions since it supports the foundation with a pier driven to bedrock or equal load bearing strata which makes the repair reliable and permanent.
