Then, with clipboard in hand, i would snake myself around the entire space and make a scaled drawing of the substructure- including measurements and my notes about any problems I would find. All foundation cracks were carefully measured for width and length and then located on the drawing. To check the foundation underground, i would dig a pit next to the building perimeter to observe and record the type of soil along with the depth and configuration of the footing. Often I would dig to follow foundation cracks to see if they extended from the foundation wall down to the footing. I always carried a pointed steel probe which I would pound into the soil to measure penetration resistance. Doing the research, for each foundation and structural inspection, i would research my geology library to find out if the property was near an active fault or a known landslide. From my geology maps, i would identify the type of rock formations and soils which were known to exist in the subsurface. I would go to the local building department and pull the topographic maps and any grading plans for the site and I would get into the permit records to see if there were any soils investigations or permitted repairs which had been previously done.

The tubing was plugged into the base of the bucket which is kept stationary and for filled with water. Keeping the end of the tubing above the water level, you can move the tubing about and view the reference waterline at any particular point. By attaching the tubing along the rod, you can hold the rod in a plumb position with the bottom end on the floor and read the floor level variations from place to place. The readings are plotted on a drawing of the floor plan. Lines of equal elevation are imposed on the drawing to create a sort-of mini topographic map of the floor. Today when I want a floor-level survey, i use a high-tech device which uses a small computer and a special fluid to transmit tiny variations in barometric pressure which are then digitized and displayed to the user. This is a very handy device, good also for one-man layouts, which no self-respecting foundation contractor should be without. As a former engineering geologist, i felt comfortable doing the analytical part of the inspection, calling upon my contracting experience to develop and present the scope and cost of any foundation repairs which I would recommend. On site i would supplement the manometer survey with a detailed visual inspection of the property including drawings and notes to identify and locate all foundation cracks and other defects. Crawling and Digging, if there was a crawl space under the floor, i would put on a breathing filter, a head lamp, knee pads, and elbow pads.

A foundation Expert is Born! When I was growing my foundation repair business in San diego, california during the mid 1980s, i fashioned motto myself into one of a handful of property inspectors offering their services to the homebuyer. At that time, there was no licensing requirement and most home inspectors were contractors of one stripe or another. There were no hand-held computers with on-site cd burners like they have today. I had to create my inspection forms from scratch. It was at that time that i invented my version of the foundation and structural Inspection. My brother James, a mechanical engineer, built for me a custom manometer- really just an assembly consisting of clear surgical tubing, a bucket, and a calibrated rod.

It is usually the off real estate broker who will convince the buyer (or seller) to bring in the foundation repair expert. Heres a bit of background on the subject: California and other states now have full disclosure laws which arose after sellers and realtors started getting sued over undisclosed defects. The courts ruled that the real estate broker has the responsibility to point out any red flags. To be clear, foundation cracks are considered essay to be red flags. The legislatures took the concept of buyer beware and threw it out the window. The brokers are now protected because of laws requiring the seller to tell all in a multi-page disclosure which is built into the sales agreement. Further protection is afforded when the buyer hires a professional to inspect the property and issue a written report, itemizing all the problems which are discovered. But even the professional home inspector is not usually willing to go out on a limb concerning foundation cracks and other foundation problems. That is unless that inspector is also an experienced foundation repair contractor.

Because you need the experienced expert to distinguish between what is minor and what is a significant problem. Nobody else wants the liability of perhaps making the wrong call about a foundation crack. Red Flags and Full Disclosure. Consider the following commonplace event: One day the property owner decides to list the property with a real estate broker. An offer is accepted and people start swarming around the property- the buyers agent, bank appraisers, termite inspectors, and property inspectors. Unless the owner has piled a heavy stack of bricks in front of the foundation cracks (this happens the various professionals observe the foundation cracks and note them in their reports. A termite report might say something like this: Vertical foundation cracks in the concrete foundation wall were observed just south of the crawl space access- consult a qualified foundation specialist.

Cosmetic repairs, such as patching of foundation cracks or concrete resurfacing, may be recommended. The report should state whether any foundation movement is active or has the potential to become active in the future. Knowing how to read foundation cracks is important in this regard. Should active movement be detected, the problem is more serious and appropriate foundation repairs should be recommended. These recommendations might include one or some combination of the following: soil stabilization, soil re-compaction, slope stabilization, soil replacement, drainage correction, foundation underpinning, foundation replacement, and/or substructure repairs. Ask for a proposal, finally, your consultant should provide you with an estimate of foundation repair costs. This may come in the form of a lump sum number, an itemized list or a detailed design-build proposal.

Be aware that a contractor is much more likely to give you an estimate or bid while an engineer report will students often include the suggestion that you go elsewhere for an estimate. The ideal situation would be that the report is accompanied by a design-build proposal for your review and acceptance. Most of the time, foundation cracks do not suggest the need for expensive foundation repair work. Concrete cracks or cracks in masonry, brickwork, stucco, plaster or drywall are not uncommon in structures and often are often tolerated by property owners without consequence. Such defects will usually prove to be the result of minor errors in design, construction methods, or the result of normal expansion and contraction of materials. A property owner is not concerned with an isolated foundation crack which has not changed since the property was purchased 20 years ago. So why do so many property owners need to consult a foundation repair expert?

How do i define a qualified foundation expert? Look for a professional consultant having broad experience in foundation repair with a working knowledge of the foundation design process. The ideal candidate will hold state licenses in both civil engineering and general engineering construction. Alternatively, look for a foundation contractor who works closely with foundation engineers or a foundation engineer who works closely with foundation contractors. Most importantly- be sure that your expert has a solid track record of diagnosing and solving foundation and structural problems.


Get a written Report, your expert should be prepared to conduct a thorough foundation and structural inspection and issue a written report. The report, often called a distress analysis, should itemize all structural defects observed on the property to include foundation cracks. The report should also include observations about the property which may include comments about the geology, soils, drainage, slopes, retaining walls, foundation walls, subfloor, floor slab, general construction methods, and construction materials. The report should also provide and interpret the results of a floor-level survey, also called a manometer survey, for each building on the property. If the floor level is off, the manometer survey will illustrate the configuration of the floor and can be used, along with all other data (such as foundation cracks to draw conclusions. Your expert should be prepared to determine, within the limits of the inspection, what has caused foundation cracks and other distress. If the cause of the foundation cracks and other distress can be attributed to common construction errors, isolated forces or normal structural adjustments which have been resolved, then the report should so state.
