BEFORE YOU CALL A FOUNDATION REPAIR COMPANY,READ "FOUNDATION REPAIR SCAM" .

Everyone has an opinion on whether or not your house needs foundation repair. You see cracks in the walls and ceilings, floors are not level or your trusted friend commented that you have foundation "problems". Or you may have had a buyer that did not buy your house because a foundation repair company said you had problems. You can call a foundation repair company to give you a bid for "repairs" with sell pitches and 1000 year warranties or you can consult with a structural engineer to provide a non-biased opinion on whether or not your foundation needs to be repaired. You may need foundation repair, but wouldn't it be more valuable to have a structural engineer explain why you need the "repair" and the risks and benefits that come with it before you make the final decision?

No one can force you to get foundation repair; but there are plenty of confusing and intimidating reasons that can convince you to have this major surgery done to your house without any clear objectives in sight. We offer explanations and information for "why" you should or shouldn't get foundation repair. WE believe that understanding the risks and benefits of foundation repair will help you make better decisions for your home and family.

A-1 Engineering, LLCis a Texas structural engineering company, focused on providing home owners with information, guidance and insight into thefoundation repair process,foundation assessments for due diligence in real estate transactions,structural designs for foundations and framing,retaining wall designand structural forensic evaluations of buildings, retaining walls and other structures. Our team ofengineers and project coordinatorswork diligently to add value to your project.

Does A-1 Engineering design residential foundations?

Yes. Our structural engineers have the skill, knowledge, education, experience and training in designing foundations for:

1) Slab on ground foundations

2) Pier foundations

3) Pier and beam foundations

4) Pedestal foundation type for modular homes

We will gladly explain the design process and fee for services.

What is the difference between an assessment by A-1 Engineering and that of a foundation repair company?

You deserve a non-biased and objective opinion on whether or not your foundation will benefit from foundation repair. A foundation repair company specializes in lifting houses. A structural engineer specializes in designing and understanding buildings. If you want to spend the thousands of dollars to lift the building and see if it works, then call a foundation repair company. But if you want to understand if your building will benefit from foundation repair and discuss the risks of lifting the building, then a structural engineer that specializes in assessing homes with foundation issues. Foundation repair is major surgery to a house. Anyone that is spending thousands of dollars on major surgery without a clear understanding of why its being done will not understand the side effects when they appear. Sometimes trying to lift and “repair” your house will cause more damage than you intended.

Can A-1 Engineering assess commercial buildings with foundation problems?

Yes. In our eyes, a foundation is a foundation regardless if it for a commercial or residential use. We have and continue to design commercial buildings. Our engineers have extensive knowledge and training in designing and assessing foundations constructed with piers, foundation walls, over basements, and slabs on ground. Our engineers have the experience and training to assess building constructed with concrete tilt up panels, steel framed buildings, masonry buildings, wood buildings and buildings constructed with composite materials.

What is a due diligent assessment?

A due diligent assessment is a common term for an inspection or assessment of a property to help the buyer or seller understand the current condition of the buildings. Residential buyer and sellers do these types of assessments except the residential real estate industry calls them “home inspections”. A-1 Engineering does not offer home inspections at this time. Our engineers work with property managers, property owners, buyers, lenders and investors to complete due diligent assessments for commercial and multi-family real estate projects. Whether the property has one building or 50 buildings, we have the capability to assess the property for suspected foundation and drainage problems or structural issues for balconies or stairs.

Can A-1 Engineering develop a full set of design plans for my home or business?

A-1 Engineering is a structural and civil engineering design firm. We are not architects nor do we practice architecture. However, we can introduce you to architects for you to interview and discuss the development of your project. Our civil engineer can help you discuss civil issues that may arise. Issues, such as, platting, zoning or drainage can all be addressed by our civil engineer. Our structural engineers can then work with the architect to complete your design plans and prepare them for permitting review, pricing and construction.

What can I do now to help me monitor my foundation?

One of the best tools to help you monitor your foundation is getting a foundation elevation survey. This is not the same survey that you get for the property when you buy it. The foundation elevation survey is a floor plan of the house with elevation readings measured throughout the building. The data alone may not mean anything now, but if you have a home builder’s foundation warranty, the information will help you appeal a claim that is denied if the data supports that your house moved excessively. Read Why Warranty Companies Win Claims.

Four Common Misleading Statements from Foundation Repair Companies:

#1: Your foundation will be stabilized! Stabilizing a foundation implies the foundation will not move again. However, simply lifting your foundation by pressing concrete piles into the ground and propping the foundation up does nothing to the soils that have moved and caused the cracks in your walls to appear. As an informed consumer, understand that lifting a foundation to provide you a level floor is simply that, a leveling job; it is not a method of foundation stabilization. This means that the foundation is still susceptible to movement.

#2: Your foundation is out of tolerance! The tolerance that is quoted is a perspective tolerance and is NOT defined by our City code. The tolerance of 1” that is tossed around by foundation repair companies is not a code defined tolerance nor does the City require you to level the foundation for a 1” difference in elevation. The 1” tolerance comes from a guidance document that the American Society of Civil Engineer published. This document is guidance, not a code. If the document was a code, then a city ordinance should recognize it to make it enforceable. You may ask the foundation repair company to quote the title, section, page and paragraph of the code document that they use to claim the tolerance.

#3: The press pile will be pushed to the point of resistance or bedrock! The point of resistance may be translated to mean “effort”. Some foundation repair companies will press the concrete piles to a point that they feel is enough to lift the foundation. The point of resistance is not measured the same by all foundation repair companies. Each will claim that they have been doing “repairs” for years and they know the industry and how to “fix” a foundation. If the foundation repair industry that uses concrete pressed piles is well experienced then why do different contractors give different recommendations for the same foundation using the same concrete press pile system. Foundation repair companies typically do not test or check to see how deep the bedrock is so this is purely speculative without a geotechnical study (soils study).

#4: Your foundation “repair” comes with a life time warranty! Most foundation repair companies offer a warranty. Some offer a life time warranty. Regardless of the length of the warranty, be sure to read the section within the warranty that lays out the conditions that voids the foundation repair warranty. We once read a warranty that stated the warranty would be voided if “the foundation moved due to soil movement”. This clause clearly gave the foundation repair company an easy out since most foundation movements are caused by soil movement. Remember, a foundation typically moves when the soils move; therefore, if the concrete press pile is supported by the same problem soils then movement should be expected and the warranty may be voided.

What is a foundation survey?

If you are buying a new home or building a custom home, then you should have a foundation survey completed. A foundation survey is not a civil survey that you get if you are buying or selling a home. A foundation survey is a document that shows a schematic floor plan of your house with elevation readings throughout the floor plan. The elevation readings represent the high and low points of your foundation at the time the readings are taken. Consider it a snap shot of the current position of the foundation. The initial foundation survey is a base line of the contour of the foundation.

Why do I need a foundation survey?

If you are buying a new home or having a custom home built then the initial benefit of having a foundation survey is that the document becomes a recorded independent document that shows the elevation readings of your foundation at a point in time (date of measurement). The document can later be referenced if you ever suspect the foundation may be moving or foundation related problems. If you suspect the foundation is moving, another foundation survey can be completed and the elevation readings can be compared to provide you (or structural engineer) with information on the degree of movement, location of movement and the relative rate of movement. For example, you purchase your dream custom home tomorrow and today you had A-1 Engineering provide you with a foundation survey. The survey would show your floor plan with spot elevations throughout the floor plan. Three years from now we have a severe drought and you begin to see cracks throughout the building. Obviously you become concerned on whether you have foundation problems. Since you have a foundation survey taken today we can then remeasure the foundation three years from now and compare the differences in elevation readings to better understand the amount of movement and also determine where the movement is occurring. This information may lead you to a possible plumbing leaks or movement caused by other sources such as trees, drains, irrigations systems, settlement or septic systems. This information becomes invaluable in deciding if you should have the foundation for your custom home “repaired” or leveled.

Who needs a foundation survey?

Any homeowner that is proactive in monitoring the performance of their foundation or a homeowner that recently purchased a home. Consider the following scenarios:

Scenario #1: One year ago you watched the construction of your custom built home and now you start to see cracks throughout one wing of the house. Just before the flooring material (carpet, tile, laminate flooring, etc.) was placed you had a foundation survey completed throughout the entire floor plan. Now that you suspect possible foundation movement you have another survey completed. The data between the first and latest survey are compared and the data indicates the corner of the master bedroom has dropped 1.25 inches. You call the builder and he says that his warranty coverage takes effect if the movement is more than 1.0 inch. If you had not taken the initial survey then the builder can claim that the foundation started 0.5 inches low; hence the builder is claiming that the foundation only moved 0.75 inches (1.25” – 0.5”) and the warranty will not cover the damages. Without your initial survey taken a year ago, you have not data to contour the builder’s assumption. However, since you proactively had a foundation survey completed, the data clearly shows that the difference in elevation between then and now is greater than the 1.0 inch criteria. Keep in mind that the one inch warranty clause is used in this scenario to illustrate a point and does not imply that all home builders have similar clauses or offer a warranty.

Scenario #2: You purchased your home five years ago now you see cracks within one of the walls of the main corridor. You call a foundation repair company to give you a quote on possible foundation repairs. The four contractors that you call tell you that the foundation has dropped 2 inches across the front of the house as a result of the drought and this drop is what caused the damage. They recommend a foundation repair of $10,0000 to bring the foundation back to where it started. You go to your file cabinet and pull out the foundation survey that was completed just before you first moved in. According to the survey the front wall was already 1.5 inches low when you first bought the house and it did not have all the cracks that are now showing up. Instead of agreeing on foundation repair you have another foundation survey completed and the data indicates the restroom near the corridor is 0.5 inches higher. Without the initial foundation survey the current elevation readings suggest a two inch drop but according to the data the foundation has only moved 0.5 inches (keep in mind that the foundation was already 1.5 inches low when you moved in). The higher elevation measurement in the restroom may have been caused by a plumbing leak. Relating the soil movement (damage to the wall) to the plumbing leak becomes a more viable reason to the movement (proven with historical data) as opposed to just accepting that “the drought” caused the damage.

Scenario #3: You purchased your home 15 years ago and this past summer you started seeing cracks at the edges and joints of your newly remodeled kitchen. Suspecting the worse, you call a foundation repair company to provide you with a cost estimate and recommendations for foundation repair. The contractor states that you need 30 piers at a cost of $15k because your foundation has tilted and caused the damage. Again, you pull out the foundation survey that was completed 15 years ago from your file cabinet and get a current foundation survey. The data between the two surveys is compared and the data is relatively the same; suggesting the foundation has always been tilted and has moved very little. Since the foundation surveys do not suggest significant foundation movement you save the $15k in foundation repair and have the cracks assessed.

Are foundations constructed level?

Concrete contractors and custom home builders certainly try hard to construct a level foundation. The tile contractor and the framing contractor appreciate a foundation that is constructed level. However constructing a perfectly level foundation using common industry practices is not easily possible. As an analogy, consider the task of icing a square flat cake. The icing material may be pasty enough to get a smooth finish but because the icing knife is hard to control then the icing finish will have slight highs and lows. You may not be able to see the difference but they are there. That same phenomenon occurs with the construction of concrete foundations. Concrete foundations may have differences of up to ¾” to 1” inch from one side to the other (high or low). Once the concrete foundation is constructed it is not feasible to remove it and start over. Having a foundation survey once the foundation is constructed will provide you with an orientation of where the highs and lows occur. This information is valuable in monitoring the performance of a foundation. Consider the foundation survey as a baseline of where your foundation starts.

I am buying a home, should I have the foundation completed before or after I move in?

If you are considering buying a home then we recommend getting a general (Level A) structural assessment after the home inspector has completed their inspection. The structural assessment should observe the roof framing as well as the overall building condition. Buying a home that has broken or over stressed roof members may cause cracks in the ceiling that may later be mistaken for foundation problems. The structural engineer should take some general elevation readings to get a general idea of the slopes of the foundation in relation to any visible cracks. His assessment should comment on the general levelness of the foundation. If you decide to buy the home then you should ask the structural engineer to complete a foundation survey of the whole house prior to moving in. This will allow the engineer more access to the entire house for more elevation readings.

How often, after buying or building a home, should I get a foundation survey?

Obviously the first foundation survey should be completed prior to moving in, regardless if you buy a new home or have a custom home built. If you build a custom home, we recommend a foundation survey to be completed every three years after construction for the first 12 years and then as needed. This monitoring sequence allows the soils to go through 12 climatic seasons in between foundation surveys. The three year interval (12 climatic seasons) assumes the foundation will experience one very rainy year, one drought and one normal year. Problems with the performance of the foundation is more likely to be identified early.

If you are buying a home the sequence of monitoring the foundation performance is relative to the age of the foundation. If you buy fairly new custom built home (5 years or less) then the three year interval previously mentioned is suggested. If the home is older then we recommend consulting with a structural engineer to help you plan the sequence of foundation surveys to monitor the foundation performance.

Regardless if you buy a new home or build a custom home, we recommend a foundation survey if you suspect foundation movement. Some cracks are misinterpreted as being caused by foundation movement and homeowners are convinced to “repair” a foundation that has moved very little (performing relatively well). The foundation survey for new home buyers is the most valuable document to monitor and detect possible foundation problems.

What would Confucius say about a foundation survey?

“It is better to have the information and not need it, then need the information and not have it”.
