Case Study

Procedure & Observations:
CERATECH personnel arrived on site to perform an application of Pavemend TR™ in support of an ongoing evaluation of product viability as an overlayment and flooring solution. The underlying principle for this application is to exhibit the ability to utilize Pavemend as a repair and overlayment element focused on high traffic areas subjected to varying loads.

The site consisted of an interior slab with varying degrees of degradation. The center section of the repair site was a full depth placement of a Portland Cement Concrete. This initial repair was performed by Penta as standard practice for repairs of this type. The repair section (~8’ x 5’4” x 1”) was prepared by Penta Construction prior to our arrival on site. After inspection and removal of residual elements of the failed flooring and inspection of the previously placed concrete, the area was swept clean to remove any contaminants. Some shrinkage cracks were noted and discussed in the new concrete.

The application was on an interior slab with ambient and surface temperatures of 68°F, material temperatures of 57°F and a starting water temperature of 62°F. To help increase productivity the water was tempered to 72°F to maintain a mixing time of 4.5 minutes or less. All materials were mixed to a critical mix temperature of 90F before placement. The parameter of the repair site was utilized to bring the application to grade with an adequate coverage of 1 to 1½” over the target surface.

The product was mixed by CERATECH representatives to demonstrate proper technique and subsequently handed off to members of the Penta group. CERATECH personnel placed product to display ease of use and the engineered properties of the product.
