Poet Rupert Brooke once wrote that good shall come of water. He obviously never dealt with concrete. One of the lesser known yet more frustrating sources of water damage can occur on a concrete slab on grade. A concrete slab on grade is a flat area of concrete, poured directly on the earth or water membrane. This is where flooring – wood, carpet, tile, – is laid in residential construction.
Water or water vapor rising out of a concrete slab on grade can cause adhesion loss, warping, peeling and an unacceptable appearance of resilient floor coverings. Beneath seamed, continuous flooring, moisture can also cause adhesive deterioration, ripping or separation of seams and air bubbles or efflorescence deposits. Other harmful effects include damage to flat electrical cable systems, buckling of carpet or carpet tiles, odors, and fungi growth.

Destructive testing is much like exploratory surgery – intrusive, expensive, uncomfortable, inconvenient and the last resort for determining the cause of a problem. Every effort should be made prior to destructive testing to evaluate the nature of the complaint. And like surgery, the expert conducting the destructive testing should know what he is looking for and be prepared for whatever he may find. This is because destructive testing, if not handled properly by attorneys and their experts, can accomplish little and may actually damage a plaintiff’s case.

As engineers, we like to think that we are doing some service to society by getting involved in lawsuits and helping to sort out engineering truth from engineering fiction. We also like to think that, somewhere, somehow, for some reason, somebody is paying attention to our expert opinions and changing the way they do business to correct design, construction or operational flaws. Then again, the lawsuit may settle without anyone learning from the mistakes.

Many investigations related to construction involve the use of concrete; and, frequently, it seems that the concrete is not performing as anticipated. Such problems often are related to cracking of the concrete, but cracking is usually only the most visible manifestation of a problem.
The adjacent figure shows crack patterns on concrete panels that are the results of field research performed in Southern California some years ago. This research showed that once concrete is placed directly on a polyethylene membrane, it will crack at a later age with almost no regard to subsequent effort to cure the concrete. This research was submitted as part of a condition survey that resulted in the settlement of a claim by the owner for remediation of the improperly installed material.
