Walter Bell | Flooring, Coatings, & Concrete Forensic Failure Analysis + Testing

I provide forensic flooring failure analysis and expert consulting for attorneys, facility owners, managers, and other stakeholders involved in complex floor covering, coating, and concrete slab disputes. My practice is grounded in scientific investigation, engineering-grade analytical testing, and root-cause attribution.

I have extensive experience in healthcare, commercial, and industrial facilities, where flooring performance issues require disciplined forensic evaluation of materials, substrates, environmental conditions, and installation performance beyond the scope of typical inspections.

FloorSciences uses forensic methodologies to determine the root cause of flooring failures and the technical significance of observed conditions. Depending on the issue, that may include testing, evaluation, and analysis of coatings, substrates, subfloor flatness, concrete pH and in-situ relative humidity, tensile bond strength, material hardness, dimensional measurements, concrete core laboratory testing, and ground penetrating radar for subsurface investigation and slab thickness assessment.

Our highly analytical approach evaluates the interaction among the flooring system, substrate, installation process, and environment. Visible distress is often only the symptom of a deeper condition involving moisture, adhesion, compatibility, curing, contamination, or structural variability. Reliable conclusions require disciplined field investigation, accurate measurement, and an understanding of the relevant materials and standards.

FloorSciences assists in matters involving:

• Coating failures, adhesive failures, delamination, and debonding

• Blistering, cracking, bubbling, curling, buckling, and lippage

• Hollow-sounding installations, moisture-related distress, and premature flooring deterioration

• Substrate preparation, installation methods, environmental exposure, and product selection issues affecting floor covering and coating performance

• Or a combinations of these factors.

I also have extensive experience with forensic imaging, technical documentation, and data-driven scientific reporting. Forensic-grade photographs, precise measurements, and organized documentation are essential because they allow the evidence to be reviewed, challenged, and understood by counsel, insurers, contractors, and, when necessary, the trier of fact.

My background includes work on healthcare, commercial, industrial, and institutional flooring where performance expectations are high and failures can have substantial financial and operational consequences. I have been retained in disputes involving slab moisture, resinous coatings, underlayments, resilient flooring, terrazzo, and other systems where sound technical analysis is needed to separate installation issues from material limitations, substrate conditions, or environmental influences.

In addition to casework, I am the appointed Technical Contact and Task Group Chair for more than a dozen ASTM standards under development or revision for tensile bond strength, material hardness, humidity measurement, forensic imaging, and resilient floor testing. My ASTM involvement reflects active leadership in standards development, test method refinement, and technical consensus work, not simply membership in a professional organization.

Whether the issue involves moisture, adhesion, material compatibility, substrate condition, or installation performance, my objective is to provide clear, defensible, science-based conclusions grounded in objective evidence. I work with attorneys, facility owners, managers, insurers, contractors, and other stakeholders who need a forensic analysis that goes beyond routine inspection and addresses the actual cause of flooring failure.
