Simple Pressed Pilings - Foundation RepairSuperior Foundation Repair will be examining disadvantages of various foundation repair methods, over the coming weeks, with an in depth look at why these methods are inferior to Steel Piers. The first type of foundation repair we will expose is the often used method of concrete pressed pilings.

Disadvantages of Concrete Pressed Pilings

In homes with Simple Pressed Concrete Piling Foundation Repair, concrete cylinders are driven underneath the home’s foundation one on top of the other using the weight of the slab to press them down until they cannot go any further (known as the point of resistance). Unfortunately, it is impossible to tell what this point of resistance is, it could be bedrock, stable soil or unstable soil. Most engineers agree this method of Foundation Repair is not the correct solution for foundation problems because expansive soil will continue affecting pilings after installation. When the soil expands it can work it’s way in between pilings and completely nullify the support this method is intended to provide (see picture above for example of piling displacement).

There is no factor of safety built into Concrete pressed pilings

The factor of safety is defined as “the structural capacity of a system beyond the applied loads or actual loads” by Wikipedia. Because the weight of the structure is used to press the pilings down until they can go no further, simple concrete pressed pilings have a factor of safety ratio of 1:1 which means any significant weight additions, have a great potential to cause foundation instability. According to Wikipedia: “Buildings commonly use a factor of safety of 2.0 for each structural member.”  This means foundation piers should be able to support the sturcture’s weight times 2 at the least. Superior’s Steel Pier Method supports a structure’s weight comfortably with a safety factor significantly greater than 2 by anchoring the structure to solid bedrock, which prevents future additions in weight to a house, i.e. add-ons, new furniture, etc, from causing any negative affect on a home’s foundation. Superior’s Steel Piers are certified by Independent Engineer Consultants.

Pressed Pilings installed in dry or unstable soil may sink upon the introduction of moisture

Because Texas experiences long periods of dry weather followed by wet weather, the soil moisture content is continuosly changing, causing expansion/contraction of soil (further reading: Article from Geology.com, Blog post on Expansive Soils in Texas, Article from USinspect.com). Therefore pressed pilings inserted into dry soil are unstable from the start. If the point of resistance is on unstable soil, increased moisture can cause the piers to sink further into the ground, or, if the soil is stable, expansion will cause the piers to move.

Oftentimes companies will pre-soak the soil to drive the pressed pilings as deep as possible. This is to prevent the pilings from sinking in times of increased rainfall. Introducing large amounts of water into soil is not good for any home at any time, under any circumstances. Superior’s Galvanized Steel Piers are driven through the soil until they reach the bedrock up to 100 feet below the surface, effectively securing a home’s foundation to a solid rock, which is unaffected by shrinking and swelling.

Foot in the door foundation repair bidsToday we are going to take a look at the practice that some firms use called “Foot in the door” bids.

What is a “Foot in the door” bid?

  • This is a bid in which a firm comes to a house to inspect a foundation, roof, plumbing, or other service and offers a bid for partial repair, which is much lower than any of the other bids a customer receives. For the purposes of this blog we will focus on foundations.

In this example we will use Firm ABC, Firm JKL, and Firm XYZ as our firms offering bids.

  • Firm ABC comes to the house, inspects the foundation and offers a bid of $8,000 with the job lasting 3 days and minimal disturbance to garden or landscaping.
  • Firm JKL comes to the house, inspects the foundation and offers a bid of $10,000 with the job lasting only 2 days and considerable disturbance to garden or landscaping.
  • Firm XYZ comes to the house offers a bid of $3,000 for 1/4 of the house with the job lasting 3 days and disturbance to only the part of the house being repaired.

All needed repairs for a typical house with moderate foundation damage start around $8,000 -$12,000 but can go as high as $20,000 -$30,000.

Many times, a firm will come to a house, inspect a foundation and get a feel for what a customer is wanting to spend. Most people are not going to be ready to pay $8K – $12K for a foundation repair.

Possibly only part of the house is currently being affected by foundation problems. In this case firm XYZ may claim that only 1/4 of the house is currently being affected by foundation problems and that for a much lower price ($3,000 in this case) the problem can be fixed.

Sounds great, right?

Wrong!

Logically if part of a house is sagging or experiencing foundation problems the soil associated with the house is the same all over, and more than likely at some point in the future another part of the house is going to need foundation repair.

Firm XYZ knows that, once the next part of your house begins sagging, you are more than likely going to call them back to do the repairs on that part of the house. This means more disruption to your landscaping several more days of having firm XYZ at your house, and more headache.

Let’s say over 4 years your whole house ends up needing foundation repair, you pay $3000 each time firm XYZ comes out and they are there for 3 days each time. That would be a total of $12,000 dollars over 4 years plus 12 days of repair time on your house. Not to mention the time they spend coming out to inspect the house each time they are called.

Compared to the other 2 bids this would be much more time than necessary and more than both bids.So in the long run the customer would have spent much more than they had planned and would have had much more time dealing with foundation repairs than necessary.

Be smart, if a house is having foundation problems the whole house needs to be fixed, even if some parts of the house are not showing signs. Putting a band-aid on a problem doesn’t heal the wound.
