Structural Repair (Overview)                                                                                                        Back to top

Settlement of buildings, homes, additions, and swimming pools is a serious problem that affects many owners in Florida. Because of Florida's geological history, the type of shallow surface soils that support our buildings are relatively loose sands, clays, and decaying organic material.  

The most common visual indicators of foundation settlement are:

    1. Noticeable slopes in concrete floor slabs or floor framing.
    2. Cracks in exterior or interior walls, wider than 1/16".
    3. Misalignment of doors or windows (doors rubbing).
    4. Gaps below baseboards or above interior walls.
    5. Cracks in the exterior masonry.

The most common visual indicators of swimming pool settlement are:

    1. Uneven waterline compared with tile line.
    2. Cracks in pool tank, pool tile, and/or coping.
    3. Excessive sloping and/or cracking of pool deck.

While most homeowners are aware of problems with their home or swimming pool, they may not be aware that weak soil is the cause. The tendency is to treat the symptoms without addressing the underlying soil condition. Of course, this leads to remedies and patches that usually create a much more expensive repair later. Cracks should never be filled or patched until the underlying soil has been strengthened. There are multiple ways to strengthen soil and make repairs, however, not all repair procedures work on all soils. Owners should only consult companies with engineers on staff (such as us) when seeking repair options.

                                                   





















Foundation Underpinning                                                                                                             Back to top


Underpinning is the process of modifying an existing foundation system by extending it to or into subsurface strata that is deeper and more stable than the near surface soil that supports the existing foundation system. This is done to provide vertical support that is not present in the existing design. Methods of underpinning include the construction of footings, stem walls, driven piling or drilled piers.

Many of the houses that forensic engineers and repair contractors are asked to evaluate were constructed with foundations that are inadequate for the conditions existing on site. Because of the lack of suitable land, homes are often built on marginal land that has insufficient bearing capacity to support the substantial weight of a structure. As a result, underpinning is required to extend the foundation support to depths that provide greater bearing capacity and/or are less affected by climate, soil conditions and/or homeowner's actions. This underpinning, if properly designed and installed, provides the basis to lift the structure to a more acceptable elevation and provides vertical support to prevent the underpinned area from settling.

Mudjacking

Mudjacking is the process of pumping cement grout under a concrete slab in order to lift the slab. We simply drill strategically placed holes through the slab and pump cement grout (under pressure) into the soil/void beneath the slab. Lifting a slab using this method can often be accomplished by a qualified grouting crew in a typical work day.

We have successfully pressure grouted (mud-jacked), hundreds of building floor slabs throughout Florida. Please call us for a free inspection and repair proposal.

HELICAL PILES & ANCHORS

CHANCE® helical piles and helical anchors have found increasingly widespread use within the structural and geotechnical engineering industries. The increased use is a direct result of the versatility and cost-effectiveness of the helical system. The ability to be utilized in both tension and compression applications make the pre-engineered system an attractive alternative to the foundation stabilization and earth retention sectors of the construction industry.

The helical system is segmented with helical bearing plates welded to a central steel shaft. Load is transferred from the structure through the shaft to the soil through the bearing plates. Central steel shafts are available in either Type SS (Square Shaft) series or Type RS (Round Shaft) series. SS-RS combinations are available when conditions require a deep bearing strata with an increased need for lateral stability.

Segments or sections are joined with bolted couplings. Installation depth is limited only by soil density and practicality based on economics. A helical bearing plate or helix is one pitch of a screw thread. All helices, regardless of their diameter, have a standard 3" pitch. Being a true helical shape, the helices do not auger into the soil but rather screw into it with minimal soil disturbance. Helical plates are spaced at distances far enough apart that they function independently of each other as individual bearing elements; consequently, the capacity of a particular helix on a helical pile or anchor shaft is not influenced by the helix above or below it.

Swimming Pool Repair                                                                                                Back to top


Settlement and cracking of concrete swimming pools and pool decks is a common problem because of the sandy soils we have in Florida. Abnormal settlement may be the result of naturally loose soil, poorly compacted soil, buried organic material that is decaying, and/or water leaks.

The water in your pool automatically shows if your pool is sinking. Since water is always "level" a quick visual inspection of the ceramic tile pattern (compared to the water surface) will show if any area of the pool is lower than the rest of the pool.

Settlement and cracking of concrete swimming pools and pool decks is a common problem because of the sandy soils we have in Florida. Abnormal settlement may be the result of naturally loose soil, poorly compacted soil, buried organic material that is decaying, and/or water leaks.

Concrete pool decks usually experience abnormal settlement and cracking because the soil beneath them was not properly compacted during construction. Most pool contractors are reluctant to mechanically compact the soil adjacent to the pool tank for fear of braking the pool plumbing "return" lines that are buried around the perimeter of the pool. Over time this loose soil consolidates and ceases to provide adequate support for the pool deck, causing the deck to settle and crack.

Do You Have That Sinking Feeling?

By David Bryant P.E.
Certified Structure and Foundation, Inc.

Settlement of homes, additions, swimming pools, and porches is a serious problem that affects many homeowners in Florida. The obvious signs of settlement are cracking of your walls, doors or windows not closing properly, and sloping of your floor slab or outside corners of your home. If there are cracks in your pool or the waterline is uneven then you may have abnormal settlement.

Most contactors are not engineers and do not have the expertise to properly repair buildings with settlement problems. Therefore, before you do anything, contact CERTIFIED STRUCTURE AND FOUNDATION, INC. for a soil test and engineering analysis of your problem. As a structural engineer with over 30 years of experience solving settlement problems, I can help you decide how to repair your home properly and economically.

Never try a "do it yourself" fix of your settlement problem! Digging around or below your foundation and pouring concrete is a bad idea. The weak soil causing your problem is typically deeper and the additional weight (of the concrete you poured) will only accelerate the settlement.
If you do have settlement problems at your home, business, or the condominium where you live, we offer  inspections,  soil testing, and  engineering opinions covering a full range of repair options. The most common and economical repair technique is "pressure grouting" which consists of injecting cement grout into the weak soils beneath your foundation, usually beginning at a depth of 10 feet. If your home has experienced excessive settlement, it may require "underpinning" of the foundations using piers or piling to transfer the foundation loads to deeper, more stable soils. In most cases, your foundation can be lifted back to its original elevation.

Of course, you want the most economical repair solution, therefore, you would not want to underpin your home with piling capable of supporting a five story building when pressure grouting will solve your problem for a fraction of the cost. To stabilize minor settlement of one corner of your home should cost approximately $3,200 dollars for labor and materials. To underpin and lift one corner with excessive settlement could cost much more. That is why it is very important to strengthen the weak soil as soon as you notice a problem.
Contact our office for your inspection and soil test. We will perform a thorough investigation of your settlement problem and test the soil to a minimum depth of eight feet. At that point, we will be able to make engineering recommendations, which usually include several options for repair and their associated costs.

I would advise anyone with a settlement problem to "Do your homework" and get a qualified engineering opinion before you spend money to fix your building. We are the best in the business and we offer the best warranty. See our ad below and call us at 321-242-1003. We also offer a wide range of engineering and construction services that are beyond the scope of this article.
