Services / Flooring


Concrete floors, both with and without finish flooring, are subject to a range of problems that can compromise their safety, usefulness, and appearance. A problem visible on the surface may be due to something beneath the floor or many feet away. A permanent solution requires an accurate determination of the root cause of the problem.

Rolling Loads

CTLGroup can also evaluate the performance of flooring systems by testing using rolling loads in accordance with ASTM F2753-10, “Standard Practice to Evaluate the Effect of Dynamic Rolling Load over Resilient Floor Covering System.” The objective of this testing is to assess the performance characteristics and limits of the adhesive products on high point loaded traffic floors, such as those found in hospitals and other facilities. Because most flooring failures typically occur within the first year following installation, we believe that this rolling load protocol provides a rigorous exposure that can be used to evaluate serviceability of an installed floor system. As the test is being conducted, observations are recorded to note floor system distress, which includes rutting, bubbling, debonding, etc. A written report of results is provided with accompanying photographs.

How We Can Help

Whether your problem floor is located in a warehouse, freezer, medical facility, school, or other commercial building, CTLGroup can help. If consulted early in a project, we can help prevent floor troubles by guiding floor design and construction efforts. Faced with an existing floor problem, our team of materials scientists and engineers work together to determine its source and recommend practical, permanent solutions. We perform a number of tests including rolling load, shear bond, and tensile strength. Whether your floor problems involve concrete cracking, excessive moisture, resilient floor coverings, ceramic tile, carpet, resinous coatings, or epoxy terrazzo, CTLGroup has the technical knowledge and experience to solve the problem.
